Quiet Japanese morning before an important date
Foundation · Time & Calendar

Now Time Has
a Date.

Yesterday, today and tomorrow gave time direction. Now Japanese can place something on an exact day: a birthday, an appointment, a journey, or the meeting you would rather not arrive for twenty-four hours early.

01 · Enter the calendar

First, the wonderfully sensible part.

Japanese months are built with a number plus 月. Twelve months, one useful pattern — with three readings worth noticing carefully.

何月ですか。Nan-gatsu desu ka.What month is it?
9月です。Kugatsu desu.It is September.
1月ichigatsuJanuary
2月nigatsuFebruary
3月sangatsuMarch
4月shigatsuApril
5月gogatsuMay
6月rokugatsuJune
7月shichigatsuJuly
8月hachigatsuAugust
9月kugatsuSeptember
10月jūgatsuOctober
11月jūichigatsuNovember
12月jūnigatsuDecember
Watch 4月・7月・9月. They are shigatsu, shichigatsu, kugatsu. Japanese has kindly made the month system simple, then hidden three small traps in the hallway.
02 · Twelve months, one year

The numbers stay orderly. Life does not.

Months become useful because something happens inside them: rain begins, school terms change, people travel, birthdays arrive, coats disappear and eventually return.

今日は9月20日です。Kyō wa kugatsu hatsuka desu.Today is September 20.

03 · The dates that have names

Now comes the interesting part.

Many dates use number + にち. But the first ten days preserve special readings, and 14, 20 and 24 deserve their own seats at the table.

何日ですか。Nan-nichi desu ka.What date is it?
15日です。Jūgo-nichi desu.It is the 15th.
1日tsuitachithe 1st
2日futsukathe 2nd
3日mikkathe 3rd
4日yokkathe 4th
5日itsukathe 5th
6日muikathe 6th
7日nanokathe 7th
8日yōkathe 8th
9日kokonokathe 9th
10日tōkathe 10th
14日jūyokkathe 14th
20日hatsukathe 20th
24日nijūyokkathe 24th
Do not try to conquer all of these in one heroic sitting. Learn them through dates you actually use. Your birthday is unusually cooperative vocabulary.

04 · Put month and day together

A date is simply month first, then day.

9月20日 becomes kugatsu hatsuka. The structure is clean even when the day reading has personality.

今日は何月何日ですか。Kyō wa nan-gatsu nan-nichi desu ka.What is today's date?
9月20日です。Kugatsu hatsuka desu.It is September 20.
Japanese normally orders a full date from large to small: year → month → day. We will add years separately rather than asking one lesson to carry the entire calendar on its back.
05 · A date becomes personal

When is your birthday?

Calendar Japanese becomes much easier to remember when the date belongs to somebody.

Man
誕生日はいつですか。Tanjōbi wa itsu desu ka.When is your birthday?
Woman
4月4日です。Shigatsu yokka desu.It is April 4.
誕生日はいつですか。 Tanjōbi wa itsu desu ka. When is your birthday?
Woman Man
A date becomes easier to remember when somebody you care about was born on it.

06 · Real Japanese

The appointment on the fifteenth.

This is where a date stops being a vocabulary exercise and starts deciding where you need to be.

Man
予約は何日ですか。Yoyaku wa nan-nichi desu ka.What date is the appointment?
Woman
15日です。Jūgo-nichi desu.It is the 15th.
予約は何日ですか。 Yoyaku wa nan-nichi desu ka. What date is the appointment?
Woman Man
15日です。 Jūgo-nichi desu. It is the 15th.

07 · Build the language

Dates can now join what you already know.

Weekdays, relative days and clock time can all attach themselves to a calendar date. Your beginner Japanese is quietly becoming a scheduling system.

来週の2日です。Raishū no futsuka desu.It is the 2nd of next week.
また15日に。Mata jūgo-nichi ni.See you on the 15th.
今日は9月20日です。Kyō wa kugatsu hatsuka desu.Today is September 20.
08 · Practice

Read the date before translating it.

Try to see each date as one calendar idea rather than three separate pieces of grammar.

4月4日

shigatsu yokka · April 4

9月20日

kugatsu hatsuka · September 20

15日

jūgo-nichi · the 15th

Real Japan mission: find three dates already present in your own life — a birthday, appointment, booking, deadline or event. Say each one aloud in Japanese. Personal dates beat random flashcards surprisingly often.

09 · Continue your journey

Days become dates.
Dates become memory.

We write dates because days disappear. Japanese gives each one a name before it becomes memory. You can now place plans, appointments and small pieces of your own life onto the calendar.
