Months of the Year in Japanese

Japanese months are the number plus 月, gatsu. January is month one. Three of the twelve use a reading you would not predict, and those three are the whole difficulty.

The three odd readings, and the date order

Four, seven and nine normally take the safe readings yon, nana and kyū. The months take the other ones: April is shigatsu, July is shichigatsu, September is kugatsu. Yongatsu and nanagatsu are simply wrong.

Everything else is regular. Number plus gatsu, and there are no month names to memorise at all.

月 has two readings doing different jobs here: gatsu names a month of the year, getsu means a month as a length of time, as in kongetsu, this month.

Japanese dates run from largest to smallest, the opposite of Europe: 2026年5月3日 is the third of May 2026, said nisen nijūroku nen gogatsu mikka.

  • 誕生日は四月です。My birthday is in April.
  • 六月に行きます。I'm going in June.
