Telling Time and Date Expressions in Japanese

Mastering how to tell time and express dates is essential for daily life and scheduling in Japanese. This guide covers everything from hours and minutes to days of the week, months, and useful relative time expressions. Let's dive in!

Hours and Minutes

In Japanese, hours are expressed with the counter (じ, ji), and minutes with (ふん or ぷん, fun/pun). Pay attention to the pronunciation changes for minutes.

3時15分 san-ji jūgo-fun 3:15
7時半 shichi-ji han 7:30 (half past seven)
12時45分 jūni-ji yonjūgo-fun 12:45

Tip: Use 午前 (ごぜん, gozen) for AM and 午後 (ごご, gogo) for PM when needed. For example, 午前9時 (gozen ku-ji) is 9 AM.

Days of the Week

The days of the week in Japanese all end with 曜日 (ようび, yōbi). Here's the complete list:

Months of the Year

Months are straightforward: simply add (がつ, gatsu) to the number (1-12). Note that April, July, and September have slight pronunciation changes.

  • 一月 (いちがつ, ichi-gatsu) – January
  • 二月 (にがつ, ni-gatsu) – February
  • 三月 (さんがつ, san-gatsu) – March
  • 四月 (しがつ, shi-gatsu) – April
  • 五月 (ごがつ, go-gatsu) – May
  • 六月 (ろくがつ, roku-gatsu) – June
  • 七月 (しちがつ, shichi-gatsu) – July
  • 八月 (はちがつ, hachi-gatsu) – August
  • 九月 (くがつ, ku-gatsu) – September
  • 十月 (じゅうがつ, jū-gatsu) – October
  • 十一月 (じゅういちがつ, jūichi-gatsu) – November
  • 十二月 (じゅうにがつ, jūni-gatsu) – December
私は十月に日本へ行きます。 Watashi wa jū-gatsu ni Nihon e ikimasu. I will go to Japan in October.

Relative Time Words

These words are incredibly useful for talking about past, present, and future events without specific dates.

JapaneseRomanizationEnglish
昨日kinōyesterday
今日kyōtoday
明日ashitatomorrow
一昨日ototoiday before yesterday
明後日asatteday after tomorrow
先週senshūlast week
今週konshūthis week
来週raishūnext week
先月sengetsulast month
今月kongetsuthis month
来月raigetsunext month
去年kyonenlast year
今年kotoshithis year
来年rainennext year
先週、映画を見ました。 Senshū, eiga o mimashita. I watched a movie last week.
明日は忙しいです。 Ashita wa isogashii desu. Tomorrow, I am busy.

Warning: Be careful with 明日 – it's usually read as ashita, but in formal contexts, it can be asu. Similarly, 今日 is kyō, not "konnichi" (which means "hello").

Duration Expressions

To express how long something takes or lasts, use time words with duration particles like (かん, kan) for a period of time.

一時間 ichi-jikan one hour
三十分間 sanjuppun-kan for thirty minutes
一週間 isshūkan one week
一年間 ichinen-kan for one year

You can also use these with the particle (de) to indicate a time limit, or with かかる (kakaru) to express how long something takes.

駅まで十分で行けます。 Eki made juppun de ikemasu. You can get to the station in ten minutes.
その仕事は三時間かかりました。 Sono shigoto wa san-jikan kakarimashita. That work took three hours.

Tip: For approximate durations, add ぐらい (gurai) or ほど (hodo) after the time expression. For example, 一時間ぐらい (ichi-jikan gurai) means "about one hour."

Practice

Try translating these sentences into Japanese:

  1. The meeting is at 2:30 PM on Friday.
  2. I studied for two hours yesterday.
  3. She will come to Japan next month.
  4. We watched a movie for three hours.

Answers:

  1. 会議は金曜日の午後2時半です。 (Kaigi wa kin'yōbi no gogo ni-ji han desu.)
  2. 昨日、二時間勉強しました。 (Kinō, ni-jikan benkyō shimashita.)
  3. 彼女は来月日本に来ます。 (Kanojo wa raigetsu Nihon ni kimasu.)
  4. 私たちは三時間映画を見ました。 (Watashitachi wa san-jikan eiga o mimashita.)

Summary and Key Takeaways

  • Use (ji) for hours and (fun/pun) for minutes.
  • Days of the week end with 曜日 (yōbi).
  • Months are numbers + (gatsu).
  • Memorize common relative time words like 昨日 (kinō), 今日 (kyō), and 明日 (ashita).
  • Use (kan) to express durations.
  • Practice combining these with particles to form natural sentences.

With these expressions, you'll be able to schedule, plan, and talk about time confidently in Japanese. Keep practicing, and soon it will become second nature!
