Korean Time Particle `에`: Marking 'When' Something Happens
에 pinpoints a specific time for an action, but never use it with 'today', 'tomorrow', or 'yesterday'.
Grammar Rule in 30 Seconds
Use the particle `에` after time words to specify exactly when an action occurs.
- Use `에` with specific times (e.g., 3 o'clock): 3시에 만나요 (Let's meet at 3).
- Use `에` with days of the week: 월요일에 가요 (I go on Monday).
- Do NOT use `에` with relative time words like 'today', 'tomorrow', or 'now'.
Overview
The Korean particle 에 (e) serves a fundamental role in marking specific points in time. It functions similarly to English prepositions like 'at', 'on', or 'in' when referring to when an event occurs. This particle attaches directly to various time-related nouns, anchoring an action or state to a precise moment on the timeline.
Understanding 에 is crucial for constructing clear and natural-sounding Korean sentences that convey temporal information.
Linguistically, Korean employs particles to delineate the grammatical function of nouns within a sentence. 에 specifically acts as a locative particle, indicating the 'location' of an event, whether that location is physical space or a point in time. When applied to time, 에 transforms a time noun into an adverbial phrase, answering the question 'when?'.
Mastering its usage, particularly discerning when it is required versus when it is omitted, is a cornerstone of A1 Korean grammar.
How This Grammar Works
오전 9시 (o-jeon ahop-si, 9 AM) becomes 오전 9시에 (o-jeon ahop-si-e, at 9 AM) to indicate when something like a meeting (회의) takes place. It doesn't change based on the preceding noun's final consonant or vowel, making its application straightforward.에's use with time nouns is specificity. It attaches to nouns that represent clearly defined, fixed temporal units such as hours, days of the week, dates, months, seasons, or specific parts of the day. For instance, you would use 에 with 일요일 (il-yo-il, Sunday) to say 일요일에 (il-yo-il-e, on Sunday) but not with 오늘 (o-neul, today), because 오늘 is a relative time adverb that already carries specific temporal meaning.에 is never used to indicate the duration of an event, nor does it specify the location where an action physically occurs (that role belongs to 에서). Its sole purpose in the context of time is to pinpoint when something happens. For instance, 저녁 7시에 집에 갈 거예요 (jeo-nyeok ilgop-si-e jip-e gal geo-yeo) means "I will go home at 7 PM," clearly marking the time of departure.Formation Pattern
에 is one of the simplest grammatical structures in Korean. You take a time-related noun and attach 에 directly to its end. There are no phonological changes or irregularities based on the preceding noun's ending (vowel or consonant). This makes 에 a very predictable and user-friendly particle for beginners.

When To Use It
에 when you need to specify a particular, fixed point in time at which an action, event, or state occurs. This includes various temporal references that are precisely definable on a calendar or clock. The key is that the time word itself denotes a single, discrete moment or period, rather than an unspecified or relative duration.- Specific Clock Times: When stating an hour and, optionally, minutes. For example,
세 시에(se si-e, at 3 o'clock),오후 7시 30분에(o-hu ilgop-si sam-sip-bun-e, at 7:30 PM). This is one of the most common applications of에. 저는 매일 아침 8시에 출근해요.(jeo-neun mae-il a-chim yeodeol-si-e chul-geun-hae-yo.) - "I go to work at 8 AM every morning."- Days of the Week: When referring to a specific day from Monday to Sunday. For example,
월요일에(wol-yo-il-e, on Monday),수요일에(su-yo-il-e, on Wednesday). Each day is a distinct point in the week. 이번 주 토요일에 영화를 볼까요?(i-beon ju to-yo-il-e yeong-hwa-reul bol-kka-yo?) - "Shall we watch a movie this Saturday?"- Dates (Day, Month, Year): When specifying a full date or part of one.
에attaches to the most specific unit. For instance,2025년 1월 1일에(i-cheon i-sib-o-nyeon il-wol il-il-e, on January 1, 2025). 저의 생일은 11월 23일에 있어요.(jeo-ui saeng-il-eun sip-il-wol i-sib-sam-il-e isseoyo.) - "My birthday is on November 23rd."- Months and Years: When referring to a specific month or year.
3월에(sam-wol-e, in March),2024년에(i-cheon i-sib-sa-nyeon-e, in 2024). 내년에 유럽에 여행 갈 거예요.(nae-nyeon-e yu-reop-e yeo-haeng gal geo-yeo.) - "I'm going to travel to Europe next year."- Seasons: When referring to the specific seasons of the year.
봄에(bom-e, in spring),여름에(yeo-reum-e, in summer),가을에(ga-eul-e, in autumn/fall),겨울에(gyeo-ul-e, in winter). 한국의 겨울에 눈이 많이 와요.(han-gu-geui gyeo-ul-e nun-i man-i wa-yo.) - "It snows a lot in winter in Korea."- Specific Parts of the Day:
아침에(a-chim-e, in the morning),점심에(jeom-sim-e, at lunchtime),저녁에(jeo-nyeok-e, in the evening),밤에(bam-e, at night),새벽에(sae-byeok-e, in the dawn/early morning). These are considered fixed points within a 24-hour cycle. 밤에 혼자 다니지 마세요.(bam-e hon-ja da-ni-ji ma-se-yo.) - "Don't go alone at night."
When Not To Use It
에 is strictly not used with certain temporal expressions. The primary reason for this omission is that these words are already inherently adverbial (functioning as adverbs of time) and, crucially, often refer to time relative to the moment of speaking or are themselves broad, non-specific temporal adverbs. Adding 에 to these words would be redundant or grammatically incorrect, making the sentence sound unnatural to a native speaker.에.오늘(o-neul, today)어제(eo-je, yesterday)내일(nae-il, tomorrow)모레(mo-re, the day after tomorrow)그저께(geu-jeo-kke, the day before yesterday)지금(ji-geum, now)아까(a-kka, a moment ago)방금(bang-geum, just now)
- Incorrect:
내일에 만나요.(nae-il-e man-na-yo.) - Correct:
내일 만나요.(nae-il man-na-yo.) - "See you tomorrow."
언제 (eon-je, when?) is an adverb asking about time and does not take 에.- Incorrect:
언제에 갈 거예요?(eon-je-e gal geo-yeo-yo?) - Correct:
언제 갈 거예요?(eon-je gal geo-yeo-yo?) - "When are you going?"
에 when they directly modify the verb's frequency, as they describe how often rather than at what specific point. However, they can be part of a larger time noun phrase that does take 에 (seeTime Particle Formation
