Japanese Months and Dates: A Simple Beginner Guide

By LanguaCards Team
3 November 2026

Japanese months and dates are built from numbers. A month is a number plus gatsu (月), so March is sangatsu, "three month". A day of the month is usually a number plus nichi (日), but the first ten days and a few others have their own names. Dates are written year, month, day.

What are the months of the year in Japanese?

There are no special names to learn. Take the number from 1 to 12 and add gatsu. If you already know how to count, you know most of the months. Our guide to Japanese numbers from 1 to 100 covers the numbers themselves.

EnglishJapaneseRomaji
January一月ichigatsu
February二月nigatsu
March三月sangatsu
April四月shigatsu
May五月gogatsu
June六月rokugatsu
July七月shichigatsu
August八月hachigatsu
September九月kugatsu
October十月jūgatsu
November十一月jūichigatsu
December十二月jūnigatsu

Three months catch most learners out, because the number has more than one reading and only one is used here.

To ask which month it is, use nangatsu (何月, which month).

How do you say the days of the month in Japanese?

This is the harder part. Most days follow the simple rule: number plus nichi. The 11th is jūichinichi (十一日), the 15th is jūgonichi (十五日) and the 30th is sanjūnichi (三十日). The 17th and 27th use shichi (jūshichinichi, nijūshichinichi), and the 19th and 29th use ku (jūkunichi, nijūkunichi).

The days below are irregular. Most of them come from the older Japanese way of counting, so they sound quite different from the usual numbers.

A few tips that help:

What is the Japanese date format?

Japanese dates go from the largest unit to the smallest: year (年, nen), month (月, gatsu), day (日, nichi). Today is written like this.

2026年10月24日
Nisen nijūroku nen jūgatsu nijūyokka.
24 October 2026.

In everyday writing the numbers are usually Arabic numerals, as above. Shorter forms such as 2026/10/24 are common too. Both styles keep the same year, month, day order, which helps if you are used to day, month, year.

How do you ask and give the date?

Two sentences cover most beginner situations.

今日は何月何日ですか。
Kyō wa nangatsu nannichi desu ka.
What is the date today?

誕生日は四月三日です。
Tanjōbi wa shigatsu mikka desu.
My birthday is 3 April.

Days of the week are a separate set of words, and they are worth learning after the dates.
