Which number system does Korean use to tell the time?

Both, on the same clock. The hour uses native Korean numbers (in their counter form) with the counter 시, so 3 o'clock is 세 시. The minutes use Sino-Korean numbers with the counter 분, so 15 minutes is 십오 분. Put them together and 3:15 is 세 시 십오 분. This is the one place the two systems always meet, which makes it the best practice for telling them apart.

How do you say "half past" in Korean?

Use 반, which means "half." 7:30 can be either 일곱 시 삼십 분 (seven hours, thirty minutes) or the shorter 일곱 시 반 (half past seven). Both are common and natural.

How do you say AM and PM in Korean?

오전 is AM (before noon) and 오후 is PM (after noon), and they go in front of the time: 오후 세 시 is 3 PM. Korean uses these far more than a 24-hour clock in everyday speech.

How do you ask what time it is in Korean?

지금 몇 시예요? means "What time is it now?" 몇 is the question word for numbers, and it turns up whenever you're asking "how many" of something, so it's worth knowing beyond the clock.

How are dates written in Korean?

Dates use Sino-Korean numbers throughout: the month takes 월 and the day takes 일, in that order. July 11th is 칠월 십일일. Two months break the pattern in spelling: June is 유월 (not 육월) and October is 시월 (not 십월), because the final consonant drops.

How to tell the time in Korean: hours, minutes, days, and dates

By Daniel · Updated 2026-07-24

Telling the time is where Korean's two number systems finally meet on one clock face, which makes it the perfect way to lock both of them in. The hour is read one way and the minutes another, and once you see the split it stays simple.

This builds directly on the numbers, so if the native and Sino-Korean sets aren't solid yet, the Korean numbers guide covers them first. Here we'll put them to work on the clock, add half past and AM and PM, then finish with the days of the week and dates.

Hours are native, minutes are Sino

Here is the whole rule. The hour uses a native Korean number in its counter form, followed by the counter 시. The minutes use a Sino-Korean number, followed by 분.

세 시
3 o'clock (native 세 + 시)
십오 분
15 minutes (Sino 십오 + 분)
세 시 십오 분
3:15 (put them together)
일곱 시 삼십 분
7:30

Set any time below and hear it read out, with the two systems colour-coded.

Half past, and AM or PM

Two shortcuts make times sound natural. 반 means “half,” so 7:30 is often just 일곱 시 반. And to mark morning or afternoon, put 오전 (AM) or 오후 (PM) in front of the time.

일곱 시 반
half past seven (반 = half)
오후 세 시
3 PM (오후 goes in front)
오전 아홉 시
9 AM

The days of the week

Every day ends in 요일. The syllable in front names it, and they follow a fixed order from Monday. You'll see them constantly in schedules and openings.

Korean	Day	Listen
월요일	Monday
화요일	Tuesday
수요일	Wednesday
목요일	Thursday
금요일	Friday
토요일	Saturday
일요일	Sunday

To ask which day it is: 무슨 요일이에요?(“What day is it?”).

Dates

Dates are entirely Sino-Korean, and the order is month then day: the month takes 월, the day takes 일. July 11th is 칠월 십일일.

칠월 십일일
July 11th (7-month, 11-day)
유월
June (spelled 유월, not 육월)
시월
October (spelled 시월, not 십월)

Only two months bend the spelling: June is 유월 and October is 시월, where the final consonant of the number drops for easier pronunciation. Every other month is just the Sino number plus 월.

Common mistakes

Using Sino numbers for the hour. 삼 시 should be 세 시. Hours are native, and they take the contracted counter form (셋 becomes 세).
Using native numbers for the minutes. The minutes are Sino, so 15 past is 십오 분, never 열다섯 분.
Spelling June and October the regular way. They are 유월 and 시월, not 육월 or 십월.
