Days, Months, and Dates in Korean: The Complete Reference

How to say and understand dates in Korean: days of the week, months, date formats, and how to say 'last week' and 'next month'.

Dates in Korean are more logical than in English. Once you know the pattern, everything follows.

Days of the week

Days in Korean all end in 요일 (yoil, "day of the week"):

DayKoreanHanja meaning
Monday월요일 (woryoil)月 Moon
Tuesday화요일 (hwayoil)火 Fire
Wednesday수요일 (suyoil)水 Water
Thursday목요일 (mogyoil)木 Wood
Friday금요일 (geumyoil)金 Gold/Metal
Saturday토요일 (toyoil)土 Earth
Sunday일요일 (iryoil)日 Sun

These follow the Chinese Five Elements + Sun and Moon. The same system is used in Japanese. Learning the Hanja (木, 火, 水, 金, 土) makes them easier to remember.

Shorthand: 월, 화, 수, 목, 금, 토, 일 (used in calendars, schedules)

Months

Months are just Sino-Korean numbers + 월 (month):

1월 = 일월 (January) through 12월 = 십이월 (December)

No special names. 3월 = 삼월 (March). 11월 = 십일월 (November). It's completely regular.

Date format

Korean dates go: Year → Month → Day (largest to smallest)

2026년 4월 10일 = April 10, 2026

년 = year, 월 = month, 일 = day

Reading: 이천이십육 년 사월 십일 일

Today, yesterday, tomorrow

WordKorean

The day before yesterday그저께

Sample sentences

오늘이 무슨 요일이에요? What day is today? 오늘이 몇 월 며칠이에요? What's today's date? (Month and day) 생일이 언제예요? When is your birthday? 제 생일은 5월 20일이에요. My birthday is May 20th. 다음 주 수요일에 시험이 있어요. I have an exam next Wednesday.


Dates come up in every conversation. Being able to express when things happen is fundamental. And the system is admirably regular once you know the numbers.

For structured vocabulary building with spaced repetition, a structured Korean course has a time and date module as part of its foundational curriculum.
