How to say dates and count days in Japanese

日 (か・にち)

Dates 1 to 10 have their own readings: ついたち, ふつか, みっか, よっか, いつか, むいか, なのか, ようか, ここのか, とおか. From 11 it is にち, with three exceptions.

Dates of the month (also "for … days", except the 1st)

11日ついたち
22日ふつか
33日みっか
44日よっか
55日いつか
66日むいか
77日なのか
88日ようか
99日ここのか
1010日とおか
1414日じゅうよっか
2020日はつか
2424日にじゅうよっか
1111日じゅういちにち

Highlighted readings are the irregular ones.

How many?

Ask with 何日 (なんにち).

The same words count days (for two days: ふつか), except one day, which is いちにち. The 1st of the month is ついたち.

よっか (4th) and ようか (8th) sound alike and are a classic listening trap.

Examples

Tap a kanji for its reading.

  • 誕生日は五月二十日です。My birthday is May the 20th.
  • 三日間、京都に泊まりました。I stayed in Kyoto for three days.
  • 今日は何日ですか。What's the date today?
  • 一日に八時間働きます。I work eight hours a day.
