कब तक

kab tak Top 2,000

At the A1 beginner level, learning 'कब तक' (kab tak) is essential for basic survival communication in Hindi. When you first start learning Hindi, you need to know how to ask simple questions about time, especially when traveling, shopping, or meeting people. 'कब तक' translates to 'until when' or 'by what time'. It is made of two simple words you should already know: 'कब' meaning 'when', and 'तक' meaning 'until' or 'up to'. At this stage, you will mostly use it with simple future tense verbs to ask when something will happen or finish. For example, if you are waiting for a train, you can ask 'ट्रेन कब तक आएगी?' (By when will the train come?). If you are at a shop and want to know when it closes, you ask 'दुकान कब तक खुली है?' (Until when is the shop open?). The grammar is very simple: you just put 'कब तक' before the verb. The answers you receive will usually include the word 'तक' as well, such as 'पाँच बजे तक' (until 5 o'clock) or 'कल तक' (until tomorrow). Memorizing this phrase allows you to manage your schedule and understand basic deadlines in a Hindi-speaking environment. It is one of the top 10 most useful question phrases for a beginner to master, as it directly helps you navigate daily life, transportation, and basic social interactions without needing complex vocabulary.

At the A2 elementary level, your use of 'कब तक' (kab tak) expands beyond simple survival phrases into more conversational and routine contexts. You are now able to use it to discuss daily habits, work schedules, and personal plans. While A1 focused on basic future events (like a train arriving), A2 allows you to use 'कब तक' with present continuous tenses to ask about ongoing actions. For example, you can ask a friend, 'तुम कब तक काम कर रहे हो?' (Until when are you working?). You also start to understand the difference between asking for a specific time and asking for a general timeframe. At this level, it is crucial to clearly distinguish 'कब तक' (until when - looking forward) from 'कब से' (since when - looking backward). A common A2 mistake is mixing these up. You should also practice using 'कब तक' with modal verbs, such as 'मुझे कब तक इंतज़ार करना पड़ेगा?' (Until when will I have to wait?). This shows a higher level of grammatical competence. You will hear this phrase frequently in everyday scenarios: parents asking children when they will finish studying, friends coordinating weekend plans, or colleagues discussing task deadlines. By mastering 'कब तक' at the A2 level, you can actively participate in planning and scheduling conversations, making your Hindi sound much more natural and interactive.

At the B1 intermediate level, 'कब तक' (kab tak) becomes a tool for more nuanced communication, including expressing mild frustration, negotiating deadlines, and discussing abstract concepts of time. You are no longer just asking for literal clock times; you are using the phrase to manage expectations and navigate social situations. For instance, in a professional setting, you might negotiate by asking, 'हम इस प्रोजेक्ट को कब तक टाल सकते हैं?' (Until when can we postpone this project?). You also begin to use it rhetorically. If someone is taking too long to get ready, you might say, 'मैं कब तक तुम्हारा इंतज़ार करूँ?' (How long am I supposed to wait for you?). Here, the question isn't necessarily seeking a specific time, but rather expressing impatience. At the B1 level, you should also be comfortable using 'कब तक' in complex sentences with dependent clauses, such as 'जब तक तुम नहीं बताओगे, मैं कब तक अंदाज़ा लगाता रहूँगा?' (As long as you don't tell me, until when will I keep guessing?). You will also encounter it in passive voice constructions, like 'यह काम कब तक किया जाएगा?' (By when will this work be done?). Understanding these varied applications allows you to use Hindi more flexibly, adapting your tone and structure to fit both formal workplace environments and casual, emotional conversations with friends.

At the B2 upper-intermediate level, your comprehension and usage of 'कब तक' (kab tak) should be near-native in terms of pragmatics and emotional resonance. You understand that 'कब तक' is frequently used in Hindi to express existential or emotional limits. In arguments or deep discussions, phrases like 'हम कब तक यह अन्याय सहेंगे?' (Until when will we tolerate this injustice?) are common. The phrase shifts from a simple logistical tool to a powerful rhetorical device used in debates, opinion pieces, and emotional dialogues. At this level, you should also effortlessly navigate the subtle differences between 'कब तक', 'किस समय तक', and 'कितनी देर', choosing the exact right phrase for the context without hesitation. You can use it seamlessly in hypothetical or conditional scenarios: 'अगर बारिश नहीं रुकी, तो हम कब तक यहाँ फँसे रहेंगे?' (If the rain doesn't stop, until when will we be stuck here?). Furthermore, you are able to understand idiomatic or poetic uses of the phrase in Hindi literature, songs, and movies, where 'कब तक' often symbolizes the pain of waiting or the longing for a resolution. Your ability to use 'कब तक' to convey tone—whether it's professional urgency, personal annoyance, or philosophical questioning—marks your transition into advanced fluency.

At the C1 advanced level, 'कब तक' (kab tak) is fully integrated into your linguistic repertoire, and you use it with sophisticated stylistic variation. You recognize its role in formal discourse, political debates, and journalistic writing. In a news debate, a journalist might aggressively ask a politician, 'जनता कब तक झूठे वादों पर विश्वास करेगी?' (Until when will the public believe false promises?). You understand how the intonation and stress on 'कब' versus 'तक' can alter the sentence's impact. Stressing 'तक' emphasizes the limit of endurance, while stressing 'कब' emphasizes the uncertainty of the timeline. You are also adept at using it in highly complex, multi-clause sentences involving subjunctive moods and passive constructions. For example: 'यह तय करना मुश्किल है कि यह स्थिति कब तक बनी रहेगी।' (It is difficult to determine until when this situation will persist). At C1, you don't just know what the phrase means; you know how to wield it to persuade, challenge, or evoke emotion. You can easily comprehend its usage in classic Hindi literature and contemporary editorial pieces, where it is often used to question societal norms or human endurance. Your mastery of 'कब तक' at this level demonstrates a deep cultural and linguistic understanding of how Hindi speakers conceptualize and debate time, patience, and limits.

At the C2 mastery level, your understanding of 'कब तक' (kab tak) encompasses its deepest philosophical, literary, and cultural dimensions. You appreciate how the concept of waiting and the limits of time are deeply ingrained in South Asian poetry (such as Ghazals) and philosophy, where 'कब तक' is a recurring motif representing the eternal wait for the beloved or for divine intervention. You can analyze sentences like 'आख़िर कब तक इंसान अपनी फितरत से भागेगा?' (Ultimately, until when will man run from his own nature?), recognizing the existential weight the phrase carries. You use it flawlessly in spontaneous, high-level academic or professional discourse, employing it to critique long-term policies or abstract societal trends. You are also aware of regional variations and colloquial shortenings in spoken Hindi, though you maintain perfect standard usage in writing. At this pinnacle of fluency, 'कब तक' is not just a vocabulary item; it is a lens through which you can express complex emotional states, challenge systemic issues, and engage in the highest levels of rhetorical debate in Hindi. You intuitively grasp the unsaid implications when a native speaker uses the phrase, reading between the lines to understand their true level of patience, hope, or despair.

Practice it Examples Notes & Tips

कब तक in 30 Seconds

Means 'Until when' or 'By what time'.
Combines 'कब' (when) and 'तक' (until).
Used to ask for deadlines or endpoints.
Can express frustration ('How long must I wait?').

The Hindi phrase 'कब तक' (kab tak) is a fundamental interrogative expression used to inquire about the duration, endpoint, or deadline of an action, event, or state. Linguistically, it is composed of two distinct words: 'कब' (kab), which is the interrogative pronoun for 'when', and 'तक' (tak), which is a postposition meaning 'until', 'up to', 'as far as', or 'by'. When combined, they literally translate to 'until when' or 'by what time'. This phrase is indispensable in daily Hindi conversation, serving as the primary tool for asking about time limits and expected completions. Understanding its semantic range is crucial for learners, as it bridges the gap between simple time inquiries and complex duration-based questions. In English, this concept is often expressed using phrases like 'how long', 'until when', 'by what time', or 'how much longer'. However, the Hindi usage is highly specific to the endpoint of a timeframe rather than the total volume of time (which would be 'कितनी देर' - kitni der).

Literal Translation: कब (When) + तक (Until) = Until when.

तुम कब तक आओगे?

The usage of 'कब तक' implies that an action is either currently ongoing and will stop at some point, or it is a future action that has a deadline. For instance, if you are waiting for a friend, you are asking for the specific moment their arrival will conclude your waiting period. Furthermore, 'कब तक' can be used in rhetorical contexts to express frustration or impatience. When someone says 'मैं कब तक इंतज़ार करूँ?' (Until when should I wait?), they are often not looking for a specific time, but rather expressing that they have been waiting too long. This dual nature—both a literal inquiry for time and a rhetorical device for expressing emotion—makes it a highly versatile phrase.

Grammatical Role: It functions as an interrogative adverbial phrase of time.

यह काम कब तक खत्म होगा?

In professional settings, it is the standard way to ask for deadlines. 'प्रोजेक्ट कब तक पूरा होगा?' (By when will the project be completed?). It sets a clear expectation for a temporal boundary.

हम कब तक यहाँ रहेंगे?

To fully master this phrase, one must practice distinguishing it from 'कब से' (since when), which looks backward in time, whereas 'कब तक' looks forward to an endpoint.

Core Meaning: Inquiring about the termination point of a temporal span.

बारिश कब तक रुकेगी?

आप कब तक काम करेंगे?

Ultimately, 'कब तक' is an essential building block for navigating time in Hindi, allowing speakers to coordinate schedules, express limits, and manage expectations effectively.

Using 'कब तक' (kab tak) correctly in a Hindi sentence requires an understanding of its syntactic placement and its interaction with various verb tenses. In Hindi, which follows a Subject-Object-Verb (SOV) word order, interrogative words typically appear immediately before the verb or the verb phrase. Therefore, 'कब तक' is most commonly placed right before the main verb of the sentence. For example, in the sentence 'तुम कब तक आओगे?' (Until when will you come? / By what time will you arrive?), 'तुम' (you) is the subject, 'कब तक' is the interrogative phrase, and 'आओगे' (will come) is the verb.

Syntax Rule: Place 'कब तक' immediately before the verb for standard emphasis.

वह कब तक सोएगा?

However, Hindi word order is relatively flexible due to its case-marking system. You can move 'कब तक' to the beginning of the sentence to place strong emphasis on the time aspect. 'कब तक तुम आओगे?' is grammatically correct and places the focus entirely on the deadline. When using 'कब तक' with different tenses, the meaning shifts slightly. In the future tense, it asks for a deadline or expected completion time: 'मीटिंग कब तक चलेगी?' (How long will the meeting last?). In the present continuous tense, it asks about the expected duration of an ongoing state: 'तुम कब तक पढ़ रहे हो?' (Until when are you studying?).

Tense Interaction: Future tense implies deadlines; present continuous implies duration of current activity.

दुकान कब तक खुली रहेगी?

It is rarely used in the simple past tense unless asking about a historical limit, such as 'वह कल रात कब तक जगा?' (Until when did he stay awake last night?). In such cases, it inquires about the endpoint of a past continuous action.

हम कब तक पहुँचेंगे?

Another important usage is with modal verbs or expressions of compulsion. 'मुझे कब तक इंतज़ार करना पड़ेगा?' (Until when will I have to wait?). Here, the phrase is combined with 'पड़ेगा' (will have to), highlighting a sense of obligation and duration.

With Modals: Used with 'पड़ेगा' or 'चाहिए' to ask about the limits of obligation.

उसे कब तक दवाई खानी चाहिए?

तुम कब तक वापस आओगे?

Mastering the placement and tense compatibility of 'कब तक' will significantly enhance your conversational fluency, allowing you to ask precise questions about time and schedules in any context.

The phrase 'कब तक' (kab tak) is ubiquitous in Hindi-speaking environments, echoing through streets, homes, offices, and public transport hubs. Its primary domain is everyday logistical planning. If you are traveling in India, you will constantly hear this at railway stations and bus stands. Passengers frequently ask officials or fellow travelers, 'ट्रेन कब तक आएगी?' (By when will the train arrive?). This is a vital survival phrase for navigating the often unpredictable schedules of public transportation.

Travel Context: Essential for asking about arrival and departure delays.

बस कब तक चलेगी?

In the workplace, 'कब तक' is the standard terminology for discussing deadlines. Managers ask their teams, 'रिपोर्ट कब तक तैयार होगी?' (By when will the report be ready?). It establishes a professional boundary for task completion. At home, it is used to coordinate family routines. A mother might ask her child, 'तुम कब तक खेलोगे?' (Until when will you play?), signaling that playtime needs an endpoint. Similarly, spouses coordinate their returns: 'ऑफिस से कब तक निकलोगे?' (By when will you leave the office?).

Domestic Life: Used to manage household schedules and daily routines.

खाना कब तक बनेगा?

Beyond literal timekeeping, 'कब तक' has a powerful emotional and rhetorical presence in Hindi culture. It is frequently used in arguments, emotional pleas, and dramatic dialogues in Bollywood movies. When a character is suffering or facing injustice, they might cry out, 'हम कब तक यह सहेंगे?' (Until when will we tolerate this?). Here, the speaker is not asking for a date and time; they are expressing that the limit of their patience has been breached.

मैं कब तक तुम्हारा इंतज़ार करूँ?

You will also hear it in news debates and political discourse. Journalists often press politicians with questions like, 'समस्या कब तक हल होगी?' (By when will the problem be solved?).

Media & Politics: Used to demand accountability and timelines from authorities.

सड़कें कब तक ठीक होंगी?

मरीज़ कब तक ठीक होगा?

In medical settings, families ask doctors about recovery times using this phrase. Its versatility makes it a phrase you will encounter in almost every facet of life in India, from the mundane to the highly dramatic.

For learners of Hindi, 'कब तक' (kab tak) is generally straightforward, but it is frequently confused with other time-related interrogatives, leading to common and sometimes confusing mistakes. The most prevalent error is confusing 'कब तक' (until when) with 'कब से' (since when). Because both phrases use the root 'कब' (when), learners often swap the postpositions 'तक' (until) and 'से' (from/since). If you want to ask someone how long they have been living in a city, you must use 'कब से' (तुम यहाँ कब से रह रहे हो? - Since when are you living here?). If you mistakenly use 'कब तक' (तुम यहाँ कब तक रह रहे हो?), you are asking 'Until when are you living here?'—implying you want to know when they will leave.

Direction of Time: 'कब से' looks to the past (start point). 'कब तक' looks to the future (end point).

गलत: तुम कब तक से इंतज़ार कर रहे हो?

Another frequent mistake is using 'कब तक' when 'कितनी देर' (how much time / how long) is more appropriate. While English uses 'how long' for both concepts, Hindi distinguishes between the endpoint of time and the volume of time. If you ask 'फिल्म कब तक चलेगी?' you are asking for the clock time the movie will end (e.g., until 9 PM). If you ask 'फिल्म कितनी देर चलेगी?' you are asking for the duration (e.g., for 2 hours).

सही: तुम कब तक काम करोगे?

Learners also sometimes redundantly combine time words, saying things like 'किस समय कब तक' (at what time until when), which is grammatically incorrect and confusing. Stick to just 'कब तक'.

Redundancy Error: Do not mix 'कब तक' with other interrogatives like 'कितने बजे' in the same clause.

गलत: कितने बजे कब तक आओगे?

Furthermore, beginners sometimes forget to use the postposition 'तक' in their answers. If asked 'कब तक?', answering just 'पाँच बजे' (5 o'clock) is colloquially acceptable but technically incomplete; the proper response is 'पाँच बजे तक' (until 5 o'clock).

जवाब: मैं शाम तक आऊँगा।

Pronunciation Note: Ensure 'कब' is pronounced with a short 'a' sound (like 'cub'), not a long 'aa' sound.

मीटिंग कब तक है?

By being mindful of these distinctions—especially the difference between 'कब तक', 'कब से', and 'कितनी देर'—learners can avoid the most common pitfalls and communicate their time-related questions with native-like accuracy.

To fully grasp 'कब तक' (kab tak), it is highly beneficial to compare it with other similar time-related interrogatives in Hindi. The Hindi language has a rich vocabulary for dividing and questioning time, and knowing the nuances between these phrases will elevate your fluency. The most closely related phrase is 'किस समय तक' (kis samay tak), which translates to 'by what time'. While 'कब तक' is broad and can refer to days, months, or hours, 'किस समय तक' specifically asks for a clock time.

कब तक vs किस समय तक: 'कब तक' is general (until when). 'किस समय तक' is specific (by what exact time).

तुम कब तक फ्री हो जाओगे?

Another highly similar phrase is 'कितने बजे तक' (kitne baje tak), which means 'until what o'clock'. This is even more specific than 'किस समय तक' and demands an answer in hours and minutes. If you ask a shopkeeper 'दुकान कितने बजे तक खुली है?' (Until what o'clock is the shop open?), you expect an answer like 'आठ बजे तक' (until 8 o'clock).

पार्टी कितने बजे तक चलेगी?

We must also revisit 'कितनी देर' (kitni der), meaning 'how much time' or 'how long' in terms of duration. While English uses 'how long' for both, Hindi strictly separates the endpoint ('कब तक') from the duration ('कितनी देर').

Endpoint vs Duration: Endpoint = कब तक. Duration = कितनी देर.

तुम्हें कितनी देर लगेगी?

There is also the phrase 'कब से' (kab se), meaning 'since when'. This is the exact opposite of 'कब तक' in terms of temporal direction. 'कब से' asks for the origin point of an action, while 'कब तक' asks for the destination point.

तुम कब से पढ़ रहे हो?

Summary of Time Questions: Mastering these variations allows for precise and natural communication in Hindi.

वह कब तक वापस आएगा?

By understanding how 'कब तक' fits into this ecosystem of time-related vocabulary, you can choose the exact right phrase for any situation, ensuring your Hindi sounds both accurate and idiomatic.

Sentence Patterns

How to Use It

note

While 'कब तक' is translated as 'how long' in English, remember that Hindi separates 'how long (deadline)' = 'कब तक' from 'how long (duration)' = 'कितनी देर'. This is the most critical usage note for English speakers.

Common Mistakes

Using 'कब तक' instead of 'कब से' when asking how long someone has been doing something.
Using 'कब तक' instead of 'कितनी देर' when asking for a duration of hours/minutes.
Forgetting to include 'तक' in the answer (e.g., saying 'पाँच बजे' instead of 'पाँच बजे तक').
Pronouncing 'कब' as 'काब' (kaab).
Using it to ask for a start time instead of an end time.

Tips

Match the Answer

When someone asks you a question with 'कब तक', try to include 'तक' in your answer. It makes your Hindi sound much more complete and natural.

Duration vs. Deadline

Memorize this rule: Deadline = कब तक. Duration = कितनी देर. This will solve 90% of mistakes English speakers make with this phrase.

Short Vowels

Make sure to pronounce 'कब' with a short 'a' sound (like 'cub'), not 'kaab'. The same goes for 'तक' (like 'tuck').

Expressing Frustration

If you want to sound like a native speaker when you are annoyed about waiting, sigh and say 'यार, कब तक?' (Man, until when?).

Listen for the Postposition

Native speakers talk fast. Train your ear to catch the 'से' or 'तक' after 'कब' to know if they are asking about the past or the future.

Keep it Near the Verb

When in doubt about word order, place 'कब तक' right before the main verb. This is always a safe and correct choice.

Soften the Question

If asking a superior, add 'सर' or 'मैडम' and use the 'आप' form: 'सर, आप कब तक फ्री होंगे?' (Sir, by when will you be free?).

Formal Alternatives

In very formal writing, you can substitute 'कब तक' with 'किस समय तक' (by what time) or 'किस तिथि तक' (by what date) for extreme precision.

Learn 'आख़िर कब तक'

Learn the phrase 'आख़िर कब तक' as a single chunk. It's a great way to express that you have reached the limit of your patience.

Daily Scheduling

Practice using 'कब तक' in your head when planning your day. 'मैं जिम में कब तक रहूँगा?' (Until when will I be at the gym?).

Memorize It

Mnemonic

Imagine a CUB (कब) TUCKed (तक) in bed, and you ask, 'Until when will the cub stay tucked in?'

Word Origin

Indo-Aryan

Cultural Context

Asking 'कब तक' directly to an elder or boss can sometimes sound impatient. It is often softened by adding 'सर' (sir) or using polite verb forms like 'कब तक हो पाएगा?' (by when might it be possible?).

In Urdu-influenced Hindi, you might hear 'कब तलक' (kab talak) which has a more poetic or dramatic flair, often used in songs and poetry.

Frequently Asked Questions

10 questions

The most literal and exact translation is 'until when'. It is used to ask for the endpoint or deadline of an action or state.

Yes, but only if you mean 'until what time'. If you mean 'how many hours/minutes', you must use 'कितनी देर' (kitni der). For example, 'How long will you stay?' is 'तुम कब तक रुकोगे?'. 'How long is the movie?' is 'फिल्म कितनी देर की है?'.

'कब तक' means 'until when' and looks forward to the end of an action. 'कब से' means 'since when' and looks backward to the start of an action.

You typically answer with a specific time or date followed by the word 'तक'. For example, 'पाँच बजे तक' (until 5 o'clock) or 'सोमवार तक' (until Monday).

It is neutral. It can be used in highly formal situations (like business meetings or news broadcasts) as well as very informal situations (like talking to friends).

It is rare but possible. You can ask 'वह कल रात कब तक जगा?' (Until when did he stay awake last night?). However, it is overwhelmingly used in the future or present continuous tenses.

'आख़िर' means 'ultimately' or 'after all'. Adding it makes the question rhetorical and emotional, expressing deep frustration, like 'Ultimately, how long must we endure this?'.

Yes. While standard Hindi places it before the verb (तुम कब तक आओगे?), placing it at the beginning (कब तक तुम आओगे?) is grammatically correct and places strong emphasis on the time aspect.

'कब तलक' is a poetic or Urdu-influenced variation of 'कब तक'. It means exactly the same thing but sounds more literary or dramatic. You will often hear it in Bollywood songs.

Yes, you must include 'तक'. If you just say 'कब', you are asking 'when' (a specific point in time), not 'until when' (a deadline). The 'तक' is essential for the meaning.
