何月
何月 en 30 secondes
- Used to ask 'which month' (1-12) on the calendar.
- Pronounced 'nan-gatsu', combining 'what' and 'month'.
- Essential for asking about dates, birthdays, and schedules.
- Different from 'nan-kagetsu', which asks for duration (how many months).
The Japanese term 何月 (なんがつ - nangatsu) is a fundamental interrogative noun used to ask 'what month' in the context of the calendar year. It is composed of two kanji: 何 (nan/nani) meaning 'what' and 月 (gatsu/getsu/tsuki) meaning 'month' or 'moon'. In the Japanese language, months are named numerically (e.g., January is 1-month, February is 2-month), which makes 何月 the direct way to inquire about the specific numerical month of an event, a deadline, or a birthday. This word is essential for basic survival Japanese, as it allows learners to navigate schedules, book appointments, and understand temporal sequences in daily life.
- Grammatical Function
- It functions as a question word that specifically targets the name of a month. Unlike English, where we have specific names like 'October' or 'May', Japanese uses numbers. Therefore, asking 何月ですか? is literally asking 'What number month is it?'
- Social Context
- This term is used across all levels of formality. Whether you are speaking to a friend about a concert or asking a doctor about a follow-up appointment, the term remains the same, though the ending (e.g., だ? vs ですか?) will change to match the social register.
お誕生日は何月ですか? (What month is your birthday?)
Understanding the distinction between gatsu and getsu is crucial. While getsu is used for days of the week (Getsuyōbi) or counting duration (ikkagetsu - one month long), gatsu is strictly for the calendar name. Thus, nangatsu specifically asks for the position in the year. If you were to say nangetsu, it would sound like a mistake or might be confused with asking 'how many months' if not phrased correctly with the counter ka.
日本へは何月に行く予定ですか? (In what month do you plan to go to Japan?)
- Calendar Systems
- Modern Japan uses the Gregorian calendar, so 何月 refers to January through December. However, in historical or poetic contexts, months had names like Mutsuki or Kisaragi. In modern conversation, 何月 strictly targets the 1-12 numerical system.
In business, 何月 is frequently paired with fiscal terms. For example, asking which month a contract ends or which month the fiscal year begins. It is a precise word. In English, we might ask 'When is the meeting?', but in Japanese, asking 何月 forces a more specific answer regarding the calendar month, whereas itsu (when) is more general and could be answered with a day, time, or year.
そのフェスティバルは毎年何月にありますか? (In what month is that festival held every year?)
卒業式は何月でしたっけ? (What month was the graduation ceremony again?)
Using 何月 (なんがつ) correctly requires an understanding of Japanese particles and sentence structure. Since it functions as an interrogative noun, it often appears at the beginning of the predicate or as the topic of the sentence. The most common structure is [Event] + は + 何月ですか? (What month is [Event]?). However, as you progress to CEFR A2 and beyond, you will need to use it with various particles to indicate time, limits, and origin.
- With Particle 'に' (At/In)
- When asking in which month an action occurs, add に. Example: 何月に日本に来ましたか? (In what month did you come to Japan?). This specifies the point in time.
- With Particles 'から' and 'まで' (From/Until)
- To ask about a duration or a range, use these particles. Example: 何月から何月まで冬休みですか? (From what month to what month is winter vacation?).
One of the most important aspects of using 何月 is the response it elicits. Because Japanese months are purely numerical, the answer will always follow the pattern [Number] + 月. This creates a very predictable and logical linguistic loop for learners. However, learners must be careful not to confuse 何月 with 何ヶ月 (nan-kagetsu), which asks 'how many months' (duration) rather than 'which month' (point in time).
テストは何月にありますか? (In what month is the test?)
In polite Japanese (Teineigo), you will almost always see 何月ですか. In casual Japanese (Futsuugo), you might simply say 何月? with a rising intonation. In very formal business Japanese (Keigo), you might hear 何月でいらっしゃいますか when referring to a client's schedule, although 何月でしょうか is more common. Using the correct particle after 何月 is the key to sounding natural. For instance, using の to link it to another noun: 何月の給料ですか? (Which month's salary is this?).
この雑誌は何月号ですか? (Which month's issue is this magazine?)
- Common Sentence Patterns
- 1. [Event]は[何月]ですか? (Basic question)
2. [何月]に[Verb]ますか? (Action in a month)
3. [何月]の[Noun]ですか? (Possessive/Attribute)
When discussing seasons or weather, 何月 is indispensable. For example, 何月が一番暑いですか? (Which month is the hottest?). Here, the particle が is used because 何月 is the subject being identified as 'the hottest'. This pattern is very common in travel planning and casual conversation about preferences.
あなたは何月に生まれましたか? (In what month were you born?)
You will encounter 何月 (なんがつ) in almost every facet of Japanese life, from bureaucratic paperwork to casual chats at a cafe. Because the Japanese calendar is so central to social and professional organization, asking about the month is a daily occurrence. Here are the primary settings where you will hear or use this word frequently.
- At the Office/Workplace
- In meetings, colleagues often discuss project timelines. You might hear: このプロジェクトは何月に終わりますか? (In what month will this project finish?). It is also common when discussing the 'Kessan' (settlement of accounts), which usually happens in March or September.
- At Schools and Universities
- The Japanese school year starts in April, which is a major cultural touchstone. Students often ask each other about exams or vacations: 夏休みは何月からですか? (From what month does summer vacation start?).
- At Travel Agencies or Hotels
- When booking a trip, the staff will inevitably ask: ご予約は何月になさいますか? (In what month would you like to make your reservation?). This is a polite way of narrowing down your travel dates.
In the media, weather forecasters frequently use 何月 when comparing historical data. They might say, 'This is the warmest June on record,' or ask rhetorical questions like 'In what month does the typhoon season usually peak?'. Similarly, in fashion magazines, you'll see phrases like 'What month's outfit is this?' to categorize seasonal trends.
お申し込みは何月から受け付けていますか? (From what month are you accepting applications?)
Socially, 何月 is a great icebreaker. When meeting someone new, asking about their birth month or their favorite month to visit a certain place is a common polite inquiry. In Japan, seasonal awareness (Shun) is highly valued, so discussing months is a way of connecting with the natural rhythm of the country. You might hear people discussing when the best time to see the autumn leaves is: 紅葉は何月が一番綺麗ですか? (In what month are the autumn leaves most beautiful?).
次回の検診は何月になりますか? (What month will the next check-up be?)
While 何月 (なんがつ) seems straightforward, English speakers often fall into several predictable traps. The most frequent error involves confusing 'which month' with 'how many months'. This is a distinction that English makes with different words, but in Japanese, it involves different counters and readings of the same kanji.
- Mistake 1: '何月' vs '何ヶ月'
- This is the 'Big One'. 何月 (nan-gatsu) asks for the calendar name (e.g., March). 何ヶ月 (nan-kagetsu) asks for the duration (e.g., 3 months). If you ask 何月日本にいましたか?, you are asking 'In what month were you in Japan?'. If you mean 'How many months were you in Japan?', you must use 何ヶ月.
- Mistake 2: Using 'Nani-getsu'
- Learners often know that 'what' can be nani and 'month' can be getsu. However, nani-getsu is incorrect. The interrogative form always uses the nan reading and the gatsu reading for calendar months.
Another common error is forgetting the irregular readings of specific months when answering the question 何月. For example, if someone asks 何月ですか? and it is April, you must say shigatsu, not yongatsu. Similarly, July is shichigatsu (not nanagatsu) and September is kugatsu (not kyuugatsu). Using the wrong number reading makes the answer sound unnatural, even if it is technically understood.
❌ 何ヶ月に日本へ行きますか? (Asking duration instead of 'which month')
✅ 何月に日本へ行きますか? (Correct: In what month...)
Confusing 何月 with いつ (itsu) is also common. While itsu is a versatile 'when', using 何月 shows a higher level of specificity. If you use itsu, you might get an answer like 'next week' or 'tomorrow'. If you specifically need to know the month for planning purposes, 何月 is the correct tool. Finally, watch out for the particle の. English speakers often say 'What month birthday?' omitting the particle. It must be 何月の... or 誕生日は何月....
❌ 何月間かかりましたか? (Trying to ask duration with 'nangatsu')
✅ 何ヶ月間かかりましたか? (Correct: How many months did it take?)
To truly master 何月 (なんがつ), you must understand how it sits within the family of Japanese time-related interrogatives. Japanese has a very structured way of asking about time, often attaching 何 (nan) to various counters. Comparing 何月 to its 'cousins' will help you choose the right word for the right situation.
- 何月 vs 何ヶ月 (Duration)
- As mentioned, 何月 asks 'Which month?' while 何ヶ月 asks 'How many months?'.
Example: 何月まで? (Until which month?) vs 何ヶ月間? (For how many months?). - 何月 vs いつ (When)
- いつ is the general 'when'. Use 何月 when you specifically expect a month as an answer. If you ask いつ日本に来ますか?, they might say 'Spring'. If you ask 何月に..., they must say 'April', 'May', etc.
- 何月 vs 何日 (What Day)
- 何日 (nan-nichi) asks for the specific day of the month. Often these are used together: 何月何日ですか? (What month and what day is it?). This is the standard way to ask for a full date.
In more formal or literary contexts, you might see いずれの月 (izure no tsuki), which is a very archaic way of saying 'which month'. However, in 99.9% of modern contexts, 何月 is the only word you need. Another alternative in business is 何月度 (nan-gatsudo), which refers to a 'monthly period' or 'fiscal month'. For example, 何月度の売上ですか? (Which month's sales are these?).
お祭りは何月何日から始まりますか? (On what month and day does the festival start?)
When talking about seasons, you might use どの季節 (dono kisetsu) which means 'which season'. While 何月 is numerical and precise, どの季節 is more descriptive. Choosing between them depends on whether you want a calendar date or a seasonal feeling. For example, 'In what month is it cold?' (何月が寒いですか?) vs 'Which season do you like?' (どの季節が好きですか?).
それは何月のニュースでしたか? (Which month's news was that?)
