Time expressions: Clock times, weekdays & relative days

Structure Japanese time expressions flawlessly: master the absolute vs relative time rule (why clock times and weekdays take に, while relative words like 今日 and 毎日 never do), time intervals with から〜まで, and question words.

Unit 5· Numbers, Counters & Time(Part 10 of 13)→JLPTN5

Relative Time Expressions (No に)

relative time
今日(きょう)
today
は
topic
predicate
楽(たの)しかった
was fun

kyou wa tanoshikatta

Today was fun.

Relative Time (今日, No に) vs Specific Day (日曜日に, With に)

Micro-Shift

今日勉強します。

I will study today.

Relative time words like 'today' function directly as adverbs without に.

Example Sentences

  • 今日(きょう)todayは楽(たの)しかったwas fun

    Today was fun

  • 明日(あした)tomorrowまたagainね

Mental Model: The Calendar Pin vs The Moving Horizon

When setting the scene in Japanese, the golden question is: Does this time word require a clock face or a printed calendar to determine its date?

  • Absolute Time Points (Require the Target Particle に): Fixed coordinates on the timeline. Pin the action using に: 7時に 起きます。(7じに おきます。) (“I wake up at 7:00.”) · 日曜日に 映画を 見ます。(にちようびに えいがを みます。) (“I watch a movie on Sunday.”).
  • Relative Time Expressions (Never Take に!): Shifting words defined relative to today: 今日(きょう), 明日(あした), 昨日(きのう), 今(いま), 毎日(まいにち). These act as floating adverbs and never take に: 明日 日本へ 行きます。(あした にほんへ いきます。) (“I go to Japan tomorrow.”) — never say *明日に 行きます!

The Essential Time Vocabulary Matrix

Master the three core categories of Japanese time coordinates:

  • Clock Hours and Minutes: Attach 〜時(〜じ) for hours and 〜分(〜ふん / 〜ぷん) for minutes: 1時 (1:00) · 2時半(2じはん) (2:30 / half past two) · 3時15分 (3:15).
  • Days of the Week (〜曜日(〜ようび)): Named after natural elements: 月曜日 (Monday / Moon) · 火曜日 (Tuesday / Fire) · 水曜日 (Wednesday / Water) · 木曜日 (Thursday / Wood) · 金曜日 (Friday / Gold) · 土曜日 (Saturday / Earth) · 日曜日 (Sunday / Sun). All take に!
  • Time Intervals (〜から 〜まで): Express spans of time from start to finish: 9時から 5時まで 働きます。(9じから 5じまで はたらきます。) (“I work from 9:00 to 5:00.”)

Asking Time Questions

To extract time information, use the specific question roots:

  • Specific Hour: 何時(なんじ) (今、何時ですか。 = “What time is it now?” · 何時に 寝ますか。 = “At what time do you sleep?”).
  • Specific Day: 何曜日(なんようび) (テストは 何曜日ですか。 = “What day of the week is the test?”).
  • General Time: いつ (いつ 日本へ 来ましたか。 = “When did you come to Japan?” Note: いつ never takes に!).

Sentence Word Order: Time Sits Early

In natural Japanese word order, time expressions are introduced very early in the sentence, usually placed directly after the main topic: 私は 毎朝 7時に コーヒーを 飲みます。(わたしは まいあさ 7じに コーヒーを のみます。) (“I drink coffee at 7:00 every morning.”).

Conversation

In Dialogue

  1. Maru

    明日何をしますか。

    What will you do tomorrow?

  2. Hana

    友達と図書館へ行きます。

    I am going to the library with a friend.

Tips and Common Traps

  • Hana· Key point

    Relative vs Absolute time words: Relative time words anchor to the moment of speaking: 今日 (today), 昨日 (yesterday), 明日 (tomorrow), 今週 (this week). Because their reference point constantly shifts, they NEVER take the particle に!

  • Maru· Common trap

    The number test for に: A foolproof golden rule: If a time expression contains an exact number or calendar date (五月五日に, 三時に), attach に. If it does not contain a specific number (今日, 毎日, 来年), DO NOT use に!

Quick Check

明日(あした)___東京(とうきょう)へ行(い)きます。Tomorrow, I will go to Tokyo.

Select the correct particle (or lack thereof) to complete: ‘Tomorrow, I will go to Tokyo.’
