Days and Dates in Japanese Chart: Weekdays, Dates, and Time Words

This is the broad reference page for Japanese day vocabulary, not just weekdays.

A good days and dates in Japanese chart needs three groups in one place: weekdays like 月曜日, calendar dates like 一日・二十日, and relative day words like 今日・明日・昨日. Once you can read all three, Japanese schedules, appointments, and beginner JLPT passages become much easier to follow.

Use に with specific weekdays and dates, but not with relative day words like 今日・明日・昨日.
