Days of the Week & Important Dates
Days of the Week & Important Dates
Learning the days of the week and how to talk about important dates is essential for daily conversation in Japanese. This lesson covers the basic vocabulary and expressions you need. We'll build upon the "Time to Learn: Hours & Minutes" lesson and prepare you for discussing family events in the next lesson, "My Family & Friends".
Days of the Week (曜日・ようび)
The days of the week in Japanese all end with 曜日 (ようび - youbi), which literally means "day of the week." The kanji used for each day corresponds to elements of nature or celestial bodies, making them easy to remember.

|---|---|---|---|---|---|
| Sunday | 日曜日 | にちようび | nichiyoubi | 日 | Sun |
| Monday | 月曜日 | げつようび | getsuyoubi | 月 | Moon |

- 今日は何曜日(きょうはなんようび)ですか？ Kyou wa nan youbi desu ka? (What day is it today?)
- 今日(きょう)は何日(なんにち)ですか？ and then ask 何曜日(なんようび)ですか？ Kyou wa nannichi desu ka? and then ask Nanyoubi desu ka? (What day of the month is it? and then ask what day of the week it is?)

Months (月・がつ)
The months in Japanese are straightforward: simply add 月 (がつ - gatsu, meaning "month") to the number of the month. For example, 一月 (いちがつ - ichigatsu) is January (first month).

|---|---|---|---|
| January | 1月 | いちがつ | ichigatsu |

Days of the Month (日・にち)
While most days of the month follow a simple pattern (number + 日 (にち - nichi)), the first ten days and the 20th have unique readings. It's important to memorize these!

| 30th | 三十日 | さんじゅうにち | sanjuunichi |
| 31st | 三十一日 | さんじゅういちにち | sanjuuichinichi |

Note the changes in pronunciation for 14th (じゅうよっか - juuyokka) and 24th (にじゅうよっか - nijuuyokka) similar to the 4th (よっか - yokka).
Putting it all together: Year, Month, and Day
When writing or saying the date in Japanese, the order is Year, Month, Day. For example, July 4th, 2024 would be:
2024年7月4日 (にせん twenty twenty よねん shizatsu tsukashi yokka) Nisen nijuyonen shichigatsu yokka.
- 年 (ねん - nen) means "year"
- 月 (がつ - gatsu) means "month"
- 日 (にち - nichi) means "day"
