How to Tell Time in Korean: Hours, Minutes, and Real-Life Phrases

To tell time in Korean, use native Korean numbers for the hour plus 시 (shee), and Sino-Korean numbers for minutes plus 분 (boon), then add 오전 (oh-jeon) for AM or 오후 (oh-hoo) for PM when needed.

Korean is spoken by roughly 82 million people worldwide according to Ethnologue (27th edition, 2024), with South Korea and North Korea as the main national centers and large diaspora communities in the US, China, and Japan. If you can say times smoothly, you unlock daily-life Korean: meeting friends, catching trains, and understanding schedules in shows and K-dramas. For more everyday openers, pair this with how to say hello in Korean.

Korean time-telling is also a neat example of how languages distribute meaning across set patterns. In Korean Grammar in Use, Ahn Jean-myung and Lee Kyung-ah present time expressions as a high-frequency “frame” learners should automate early, because it repeats constantly with small substitutions. That is exactly what we will do here.

Quick Reference: core time phrases

The building blocks: 시, 분, 초, and 에

시

시 (shee) means “o’clock” or “hour,” depending on context.

• Clock time: 세 시 (seh shee) = “3 o’clock”
• Duration: 세 시간 (seh shee-gahn) = “three hours” (notice 시간, not 시)

분

분 (boon) means “minute.” For exact times, minutes are almost always Sino-Korean numbers.

Example: 삼십 분 (sahm-ship boon) = “30 minutes.”

초

초 (choh) means “second.” You will hear it in sports, cooking, and phone settings.

Example: 십 초 (ship choh) = “10 seconds.”

-에

The particle 에 (eh) marks a point in time: “at.”

• 세 시에 (seh shee-eh) = “at 3 o’clock”
• 오후 두 시에 (oh-hoo doo shee-eh) = “at 2 PM”

Hours in Korean: native numbers (1 to 12)

For hours, Korean normally uses native Korean numbers, not Sino-Korean ones. The most important twist is that 1, 2, 3, 4, and 20 change shape before counters like 시.

In real speech, people often drop the space-like rhythm and say these quickly, but the structure stays the same: hour + 시.

Minutes in Korean: Sino-Korean numbers (0 to 59)

Minutes use Sino-Korean numbers. If you already learned Korean numbers for dates, money, or floors, this is the same set.

Pronunciation notes that prevent common mistakes

분 is pronounced boon, not “boon-uh.” The final ㄴ is an “n” sound.

십 is often heard closer to ship in careful learner pronunciation, but in fast speech it can soften. Keep ship as your reliable base.

AM and PM: 오전 and 오후

To make 12-hour time unambiguous, add 오전 (oh-jeon) for AM and 오후 (oh-hoo) for PM before the time.

• 오전 아홉 시 (oh-jeon ah-hohp shee) = 9 AM
• 오후 아홉 시 (oh-hoo ah-hohp shee) = 9 PM

This matters because Korean daily conversation often assumes context. If someone says 아홉 시에 만나 (ah-hohp shee-eh mahn-nah), they might mean 9 AM or 9 PM depending on the plan.

The main patterns you will use every day

Pattern 1: “It’s X o’clock” (시만)

If you only need the hour, you can stop at 시.

세

세 시예요. (seh shee-eh-yoh) = “It’s 3 o’clock.”

If you are speaking casually to a friend:

세 시야. (seh shee-yah)

Pattern 2: “It’s X:Y” (시 + 분)

For exact time, say hour + 시 + minute + 분.

두

오후 두 시 십오 분이에요. (oh-hoo doo shee ship-oh boon-ee-eh-yoh) = “It’s 2:15 PM.”

In conversation, you will also hear the minute part without 분 when it is obvious, but learners should keep 분 until it feels automatic.

Pattern 3: “At X:Y” (에)

Add 에 to the time phrase to mean “at.”

열한

열한 시에 전화할게요. (yeol-hahn shee-eh jeon-hwa-hahl-ggeh-yoh) = “I’ll call at 11.”

한

오전 한 시에 시작해요. (oh-jeon hahn shee-eh shee-jahk-heh-yoh) = “It starts at 1 PM” (AM in this sentence, because 오전).

Half past: 반

반 (bahn) means “half,” and with time it means “half past.”

여섯

여섯 시 반이에요. (yuh-suht shee bahn-ee-eh-yoh) = “It’s 6:30.”

This is very common in speech, especially for :30 times. For formal clarity, you can always use 삼십 분.

Quarter past and quarter to: what Koreans actually say

English learners often look for “quarter past” and “quarter to.” Korean can express these ideas, but everyday speech usually prefers the plain minute numbers.

• 3:15: 세 시 십오 분 (seh shee ship-oh boon)
• 3:45: 세 시 사십오 분 (seh shee sah-ship-oh boon)

If you want to sound natural fast, master the numeric minute system first.

24-hour time: when you will see it

Korean uses 24-hour time frequently in writing: transport timetables, apps, reservations, and official notices. You might see:

• 18:40 (meaning 6:40 PM)

When reading 24-hour time aloud, people often convert it to 오후 + 12-hour time in conversation. In some settings, especially announcements, you may hear the 24-hour number spoken with Sino-Korean numbers, but that is less consistent in casual talk.

Real-life phrases: meetings, classes, and deadlines

The goal is not just reading a clock, it is using time to manage social life politely. Korean often softens requests and scheduling with polite endings and small hedges.

늦을 것 같아요

늦을 것 같아요 (neu-jeul kkeot gah-tah-yoh) literally means “I think I will be late.” It is softer than a blunt “I’m late,” and it fits Korean preference for minimizing social friction.

If you want a more direct casual version with friends:

늦을 것 같아. (neu-jeul kkeot gah-tah)

Time words that appear constantly with clocks

These are not “time-telling” by themselves, but they glue time into real sentences.

A key distinction: 오전/오후 are clock labels (AM/PM), while 아침/저녁/밤 are daily-life periods (morning/evening/night). Mixing them is not “wrong,” but it can sound unnatural.

Common learner errors (and how to fix them)

Mixing number systems

Hours: native. Minutes: Sino.

If you say 이 시 (ee shee) for “2 o’clock,” you are using Sino-Korean 2, which is not the standard for hours. The standard is 두 시 (doo shee).

Forgetting the shortened hour forms

하나 시 is not used for “1 o’clock.” It becomes 한 시.

둘 시 becomes 두 시, 셋 시 becomes 세 시, 넷 시 becomes 네 시.

This shortening happens with counters beyond time too, so it is worth memorizing as a general pattern.

Using 시 for duration

If you mean “three hours,” do not say 세 시. That is “3 o’clock.”

Say 세 시간 (seh shee-gahn).

Saying times like English “ten to five”

Korean can express “ten minutes before five,” but most everyday speech uses the straightforward hour:minute format. If you want to be understood quickly, stick to 네 시 오십 분 (neh shee oh-ship boon) rather than translating idioms.

How this shows up in K-dramas and real speech

In shows, you will hear time in three recurring scenes:

1. Meeting coordination: 몇 시에 만나? (myeot shee-eh mahn-nah)
2. Deadlines: 몇 시까지야? (myeot shee-kkah-jee-yah) meaning “until what time?”
3. Transportation: 막차 (mahk-chah), last train, often discussed with exact times.

If you are learning through clips, time phrases are perfect because they are short, repeated, and tied to visible context (a phone screen, a wall clock, a schedule). That is the same “noticing” mechanism Richard Schmidt describes in his work on attention in second-language learning: you improve faster when you repeatedly notice the same form in meaningful situations.

For more everyday survival language you will hear in the same scenes, see how to say goodbye in Korean and how to say I love you in Korean.

Practice: say these times out loud

Read each line, then cover the Korean and produce it yourself.

• 8:00 AM: 오전 여덟 시 (oh-jeon yuh-duhl shee)
• 8:05 AM: 오전 여덟 시 오 분 (oh-jeon yuh-duhl shee oh boon)
• 12:30 PM: 오후 열두 시 반 (oh-hoo yeol-doo shee bahn)
• 6:45 PM: 오후 여섯 시 사십오 분 (oh-hoo yuh-suht shee sah-ship-oh boon)
• 9:10 PM: 오후 아홉 시 십 분 (oh-hoo ah-hohp shee ship boon)

A small politeness upgrade: asking and confirming time

Korean scheduling often includes a quick confirmation to show consideration.

괜찮아요?

일곱 시 괜찮아요? (eel-gohp shee gwen-CHAH-nah-yoh) = “Is 7 okay?”

어때요?

여섯 시 반 어때요? (yuh-suht shee bahn uh-ttheh-yoh) = “How about 6:30?”

This kind of soft negotiation fits the face-saving logic described in Penelope Brown and Stephen C. Levinson’s Politeness: Some Universals in Language Usage, where speakers reduce imposition through phrasing choices. You do not need to overthink it, but you should recognize why direct translations from English can sound abrupt.

Where to go next

Once you can tell time, the next high-value step is combining it with places and transportation phrases. If you are building everyday Korean from media, start with short, high-frequency lines and repeat them until they feel effortless.

If you want a broader base of everyday words that keep appearing around time talk, use 100 most common Korean words. And if you are curious about language you should recognize but not copy, see our guide to Korean swear words.

Finally, practice time phrases with real clips where you can see the clock, the phone screen, or the schedule. That visual anchor makes the pattern stick.
