How to Tell Time in Japanese: Days, Months, Hours & Minutes

Ever stood at a train platform in Japan, staring at the departure board, trying to decode when your train actually leaves? Or maybe you've been that person nodding along when someone suggests a meeting time, secretly panicking because you're not quite sure if they said 4:00 or 4:40.

Here's the thing about time in Japanese: it looks intimidating with all those kanji and irregular readings, but there's actually a beautiful logic hiding underneath. Unlike English where we randomly decided to call the first month "January" (seriously, where did that even come from?), Japanese just says "month 1." Simple, right?

This guide will break down everything you need to tell time, make plans, and stop missing appointments in Japan. No textbook fluff – just the patterns that actually matter.

Why Japanese Time Expressions Are Different

Japanese approaches time in a way that feels both familiar and foreign. Like English, it has specific words for days and months. Unlike English, it uses a counter system for many time expressions and follows different logic for dates.

Key differences you'll notice:

1. Counter-based system: Hours use 時 (ji), minutes use 分 (fun/pun), and days use different patterns
2. Logical numbering: Unlike English's "January, February," Japanese uses "1-month, 2-month" (一月、二月)
3. Special irregular readings: Certain dates and times have unique pronunciations
4. Context matters: The particle に marks specific times, while は marks the time frame you're discussing

Don't worry if this sounds complex – once you see the patterns, everything clicks into place.

Days of the Week

Japanese days of the week follow a beautiful pattern based on ancient Chinese elements and celestial bodies.

The Seven Days

Memory Tip

Notice the pattern: 月 (moon), 火 (fire), 水 (water), 木 (wood), 金 (metal), 土 (earth), 日 (sun)

These follow the traditional five elements (五行) plus the sun and moon. Once you learn the kanji, the days become easy!

Using Days in Sentences

Asking what day it is:

今日きょうは何なん曜よう日びですか？
Kyō wa nan'yōbi desu ka?
"What day is today?"

Answering:

今日きょうは月げつ曜よう日びです。
Kyō wa getsuyōbi desu.
"Today is Monday."

Making plans:

金きん曜よう日びに会あいましょう。
Kin'yōbi ni aimashō.
"Let's meet on Friday."

Months of the Year

Japanese months are beautifully simple. They're literally numbered 1 through 12 with 月 (gatsu) attached.

The Twelve Months

Important Notes

Special readings to watch:

• April: し月 (shigatsu), not よん月
• July: しち月 (shichigatsu), not なな月
• September: く月 (kugatsu), not きゅう月

These follow the most common readings, though you might occasionally hear alternatives in different contexts.

Using Months in Sentences

Asking about months:

誕たん生じょう日びは何なん月がつですか？
Tanjōbi wa nangatsu desu ka?
"What month is your birthday?"

Answering:

三さん月がつです。
Sangatsu desu.
"It's March."

Describing seasons:

日に本ほんでは、三さん月がつから五ご月がつまで春はるです。
Nihon dewa, sangatsu kara gogatsu made haru desu.
"In Japan, it's spring from March to May."

Dates and Days of the Month

This is where Japanese gets tricky. The first 10 days have irregular readings, and certain other dates follow special patterns.

Days 1-10 (Irregular Readings)

Days 11-31

From the 11th onwards, most days follow a more regular pattern: number + 日 (nichi)

Special irregular dates marked with * :

• 14th: じゅうよっか (not じゅうよんにち)
• 20th: はつか (not にじゅうにち)
• 24th: にじゅうよっか (not にじゅうよんにち)

Saying Full Dates

Pattern: Year + Month + Date

二千二十五年にせんにじゅうごねん三月さんがつ十五日じゅうごにち
Nisen-nijūgo-nen sangatsu jūgonichi
"March 15, 2025"

Casual version (often drops year):

三月さんがつ十五日じゅうごにち
Sangatsu jūgonichi
"March 15th"

Asking About Dates

今日きょうは何なん月がつ何なん日にちですか？
Kyō wa nangatsu nannichi desu ka?
"What's today's date?"

誕たん生じょう日びはいつですか？
Tanjōbi wa itsu desu ka?
"When is your birthday?"

Telling Time (Hours and Minutes)

Japanese time uses counters: 時 (ji) for hours and 分 (fun/pun) for minutes.

Hours (〜時)

Special readings:

• 4:00 is よじ (yoji), not しじ or よんじ
• 9:00 is くじ (kuji), not きゅうじ

Minutes (〜分)

Minutes change between ふん (fun) and ぷん (pun) depending on the sound that comes before.

Pattern for ぷん (pun):
After 1, 3, 4, 6, 8, 10 → use ぷん
After 2, 5, 7, 9 → use ふん

Half past: Use 半 (han)

三さん時じ半はん
Sanji han
"3:30" (literally "3 o'clock half")

Complete Time Examples

一いち時じ十じゅっ五ご分ふん
Ichiji jūgofun
"1:15"

七しち時じ半はん
Shichiji han
"7:30"

九く時じ四よん十じゅっ五ご分ふん
Kuji yonjūgofun
"9:45"

Asking What Time It Is

今いま、何なん時じですか？
Ima, nanji desu ka?
"What time is it now?"

AM and PM

午前 (gozen) - AM, morning
午後 (gogo) - PM, afternoon/evening

午ご前ぜん九く時じ
Gozen kuji
"9:00 AM"

午ご後ご三さん時じ半はん
Gogo sanji han
"3:30 PM"

Relative Time Expressions

These are the words you'll use constantly in conversation.

Common Mistakes to Avoid

Using に with Relative Time Words

Why: Relative time words (今日, 明日, 昨日, etc.) typically don't take に in casual speech.

Confusing Time Point vs. Duration

Mixing Up しち and よん

Why: 4 o'clock uses よ reading to avoid confusion with 死 (death).

Forgetting Half Past

Why: Using 半 for "half past" is more natural and common.

Date Order Confusion

Pattern: Year → Month → Day (largest to smallest)

Mixing Up Minutes Readings

Remember: ぷん after 1, 3, 4, 6, 8, 10 and ふん after 2, 5, 7, 9

五ご分ふん (gofun) ✓
六ろっ分ぷん (roppun) ✓

Wrapping Up: Mastering Japanese Time

Time expressions in Japanese might seem overwhelming at first, but they follow logical patterns. Here's what makes the system work:

The Bottom Line:

1. Days and months are numbered - Once you know the numbers, you know the months
2. Irregular readings exist but are limited - Mostly in the first 10 days and certain times
3. Distinguish duration from point in time - 時 vs. 時間 matters!
4. Particles matter - に for specific times, no particle for relative times
5. Half past is special - Use 半 instead of saying 30 minutes

Most Important Patterns to Remember:

• Days: Number + 曜日
• Months: Number + 月
• Dates: 1-10 are irregular, then mostly regular
• Hours: Number + 時
• Minutes: Watch for ふん/ぷん changes
• Duration: Add 間 (kan) to show duration

Practice Tips:

1. Use your daily routine - Practice saying when you do things every day
2. Read train schedules - Great real-world practice for times
3. Make plans in Japanese - Even if just with yourself, practice scheduling
4. Check Japanese calendars - Get familiar with the date format

The more you use time expressions in real contexts, the more natural they become. Before long, you'll be making plans and telling time in Japanese without having to think about the rules at all.
