Korean Months and Dates: Number + 월, With Two Traps
10-Second Answer
Korean months couldn't be simpler: Sino-Korean number + 월 (wol, month). January is 일월 (1월), December is 십이월 (12월). The only traps: June is 유월 (not 육월) and October is 시월 (not 십월) — both drop a final consonant for smoother pronunciation. Dates follow the same logic: number + 일 (day).
The Twelve Months
| Month | Korean | Watch out |
|---|---|---|
| January | 일월 (1월) | |
| February | 이월 (2월) | |
| March | 삼월 (3월) | |
| April | 사월 (4월) | |
| May | 오월 (5월) | |
| June | 유월 (6월) | ⚠️ NOT 육월 — the ㄱ drops |
| July | 칠월 (7월) | |
| August | 팔월 (8월) | |
| September | 구월 (9월) | |
| October | 시월 (10월) | ⚠️ NOT 십월 — the ㅂ drops |
| November | 십일월 (11월) | |
| December | 십이월 (12월) |
Saying Full Dates
Korean dates run big-to-small: YEAR (년) → MONTH (월) → DAY (일) — the reverse of US order. All three use Sino-Korean numbers.
오늘은 팔월 십일일이에요.
oneureun parwol sibiririeyo.
Today is August 11th.
월 then 일 — month before day, always.
생일이 며칠이에요?
saengiri myeochirieyo?
What date is your birthday?
며칠 asks for the date — and yes, 며칠 is the correct spelling, not 몇일 (a misspelling even Koreans make).
시월에 한국에 가요.
siwore hanguge gayo.
I'm going to Korea in October.
시월 — the ㅂ of 십 is gone.
Why 유월 and 시월?
육월 and 십월 are awkward to say — the final consonants ㄱ and ㅂ collide with the ㅇ of 월. Korean solved it centuries ago by just dropping them. It's the same instinct behind batchim-driven sound changes everywhere in the language: pronunciation convenience wins.
Common Mistakes
Mistake #1 — Saying 육월 or 십월
June is 유월, October is 시월 — the two exceptions worth over-learning, since calendars print 6월/10월 and hide the irregularity.
Mistake #2 — US-style day-before-month order
Korean always goes month → day: 팔월 십일일 (August 11th), never day first.
