■ The days and months in Japanese are pretty straight forward. Let's learn the days of the week, the months, and then a few "special" words to expand our vocabulary.
■ Main kanji: 日 day; 週 week; 月 month; 年 year
■ Days of the Week: You'll notice the ending stays the same: 曜日
For more on days and time, see here.
Names of the Month: For the name of the month, simply add がつ after the number. Pay special attention to the bold areas.
Days of the Month: The first ten days of the month have a number of unexpected variations.
Here are a few other words that are useful for telling the date.
■ 何曜日 What day of the week? [What "ようび"?]
■ 先 (previous): 先週 last week; 先月 last month; [But, "last year" is the irregular 去年.]
■ 来 (next): 来週 next week; 来月 next month; 来年 next year
■ 毎 (every): 毎日 every day; 毎週 every week; 毎月 every month; 毎年 every year
