Yōbi 曜日: The Days of the Week

The days of the week, yōbi 曜日(), in Japanese each start with the first character of seven luminous bodies in our solar system in the following order:  the Sun, moon, Mars, Mercury, Jupiter, Venus and Saturn.


 Nichiyōbi 日曜日


 Getsuyōbi 月曜日


 Kayōbi 火曜日


 Suiyōbi 水曜日


 Mokuyōbi 木曜日


 Kin’yōbi 金曜日


 Doyōbi 土曜日

 What day (of the week)?

 Nan’yōbi 何曜日

Reading Note: Theoretically, if you were to want to talk about hypothetical days of the week, you would read 何曜日as “naniyōbi,” but aside from this, it’s always read as above. 

All days of the week may be abbreviated by dropping the final -bi (). In abbreviated writing, you will very frequently see days of the week written with only the initial character. They can even be combined to make saying things like “Thursday and Friday” easier. Meaning, instead of writing mokuyōbi to kin’yōbi 木曜日()金曜日(), you can simply write mokukin 木金(). This is usually done in the context of scheduling.

1. 一週間(いっしゅうかん)()(なか)()何曜日(なんようび)ですか。
Isshūkan no man’naka no hi wa nan’yōbi desu ka?
What is the day of the week that is in the middle of the week?

Ashita wa nan’yō(bi) desu ka?
What day is it tomorrow?

5. 今日(きょう)何曜日(なんようび)ですか。
Kyō wa nan’yōbi desu ka?
What's today?

6. 木曜日(もくようび)水曜日(すいようび)(まえ)ですか、(あと)ですか?
Mokuyōbi wa suiyōbi no mae desu ka, ato desu ka?
Is Thursday before or after Wednesday?

7. 明後日(あさって)土曜(どよう)です。
Asatte wa doyō desu.

8. なぜ日曜日(にちようび)学生(がくせい)学校(がっこう)()かないんですか。

Nichiyōbi wa isshūkan no hajime no hi de, doyōbi wa owari no hi da.
 Sunday is the first day of the week, and Saturday is the last day.


1. Try to use the Japanese days of the week rather than in English. Get others involved to help you remember them.

2. Write out the days of the week in order 10 times. 

Hinichi 日にち: Days of the Month

  You would expect the days of the month to be the same as how you count days in general. Although this is somewhat true, several days of the month utilize native words, hybrids of Sino-Japanese and native parts, and set readings. 1-10 are especially complicated.



































































Reading Notes:

1. Tsuitachi ついたち is a contraction of tsukitachi つきたち, which means “the start of the month.” The 1st may also be ippi いっぴ in the business world. 
2. The native counter for days is -ka . It is seen in several of these phrases.

3. 7日 is traditionally read as “nanuka なぬか” and is still somewhat used.

4. The last day of a month is called “misoka  晦・三十日().” New Year's Eve is “Ōmisoka 大晦日().
5. The first three days of the New Year is called “sanganichi .”

Particle Note: The particle ni に usually follows these phrases whenever “in/on” would be used in English. However, it can frequently be omitted.

10. 今日(きょう)何日(なんにち)ですか。
Kyō wa nan’nichi desu ka?
What day is it?

11. 7(なの)()(あさ)(に)到着(とうちゃく)しました。

13. 11(じゅういち)(にち)に、(うみ)()いている(ぞう)(かい)(ぐん)(ふね)()つけました。

14. 横浜港(よこはまこう)14(じゅうよっ)日(に)ヒアリ(ひあり)500(ごひゃっ)(ぴき)くらい()つかりました。
Yokohama-kō de jūyokka (ni) hiari ga gohyappiki kurai mitsukarimashita.
About 500 fire ants were found on the fourteenth in the Port of Yokohama.

Nissū 日数: Number of Days

Days are counted with -nichi(kan) 日(間). -kan 間 is not obligatory but is used to prevent ambiguity except with the number 1. Very rarely, you’ll see it used with -kan 間 in things like forms. Incidentally, except for “one day,” all day phrases that were exceptional above are used instead with little exception.

 1 いちにち 2 ふつか(かん) 3 みっか(かん)
 4 よっか(かん) 5 いつか(かん) 6 むいか(かん)
 7 なのか(かん)
 8 ようか(かん) 9 ここのか(かん)
 10 とおか(かん) 14 じゅうよっか(かん) 17 じゅうしちにち(かん)
 19 じゅうくにち(かん) 20 はつか(かん) 24 にじゅうよっか(かん)
 27 にじゅうしちにち(かん)

Grammar Note: -kan 間 is frequently omitted when the verb kakaru かかる is used. This verb, in the sense of time, indicates how long something takes to transpire.

19. (ねつ)6(むい)日間続(かかんつづ)きました。
Netsu ga muikakan tsuzukimashita.
The/my fever continued for six days.

20. 何日(なんにち)((かん))滞在(たいざい)する予定(よてい)ですか。
Nan’nichi(kan) taizai suru yotei desu ka?

-shūkan 週間: Weeks

   The word for “week” is shū(kan) 週(間). To say “this week,” you use the word konshū 今週. For “last week,” you use senshū 先週. Like their English counterparts not being used with the prepositions “in” or “on,” neither konshū 今週 nor senshū 先週 are typically used with the particle ni に. To count weeks, you use the word for week in the form -shūkan 週間 as a counter.

 1 いっしゅうかん 2 にしゅうかん 3 さんしゅうかん
 4 よんしゅうかん 5 ごしゅうかん 6 ろくしゅうかん
 7 ななしゅうかん 8 はちしゅうかん
 9 きゅうしゅうかん

22. 仕事(しごと)でモスクワに出張(しゅっちょう)して、(そこで)2週間過しゅうかんすごしました。

26. 明日から3週間(しゅうかん)(ねが)いします。

Reading Note: Asu is slightly politer than ashita, which makes it very likely in a sentence like this.

Tsuki no Yobikata 月の呼び方: The Months

The names of the months (tsuki 月) are simply expressed with the number of the month plus the counter -gatsu 月.

 January いちがつ
 February にがつ

 October じゅうがつ
 November じゅういちがつ
 December じゅうにがつ
 ? なんがつ

Reading Note: As you can see, April and September use the not so frequently used variants of 4 and 9. You should also note that July is shichigatsu しちがつ instead of nanagatsu なながつ, which is only dialectical.

27. 日本(にほん)では新学期(しんがっき)4()(がつ)(はじ)まります。
Nihon de wa shingakki wa shigatsu ni hajimarimasu.
In Japan, new semesters begin in April.

Period of Months

-kagetsu(kan) ヶ月(間)

To generically count months, you must use the counter -kagetsu(kan) ヶ月(間).

 1 いっかげつ(かん) 2 にかげつ(かん)  3 さんかげつ(かん)
 4 よんかげつ(かん) 5 ごかげつ(かん) 6 ろっかげつ(かん)
 7 ななかげつ(かん) 8 はちかげつ(かん)
 9 きゅうかげつ(かん)
 10 じゅっかげつ(かん)
 100 ひゃっかげつ(かん) ? なんかげつ(かん)

35. (いっ)()(げつ)(やく)4(よん)週間(しゅうかん)です。

38. 5()()月間思(げつかんおも)いっきり(きん)トレしています。
Gokagetsu(kan) omoikkiri kintore shite imasu.

In the spoken language, month periods are often expressed with native phrases for 1-4 as seen below with the counter -tsuki 月. Historically, this counter could be used with more numbers. For instance, there is an old phrase, totsuki tōka 十月十日, which refers to day 10 of the 10th month to refer to how long pregnancy typically is. Outside of such set phrases, though -tsuki 月 is not outside the numbers 1-4.

 1 ひとつき 2 ふたつき 3 みつき 4 よつき

39. 一月(ひとつき)3000(さんぜん)(えん)です!
Hitotsuki sanzen’en desu!
It’s 3,000 yen a month!

41. 三日(みっか)でも三月(みつき)でも(かま)いませんよ。
Mikka demo mitsuki demo kamaimasen yo.

Period of Years

-nen(kan) 年(間)

The counter for year is -nen(kan) 年(間). This counter is also one of the handful of counters in which 4 must be read as "yo よ."

 1  いちねん(かん) 2 にねん(かん) 3 さんねん(かん)
 4 よねん(かん) 5 ごねんかん 6 ろくねん(かん)
 7 ななねん(かん)
 8 はちねん(かん) 9 きゅうねん(かん)
 10 じゅうねん(かん) 14 じゅうよねん(かん) 100 ひゃくねん(かん)

When used to refer to what year it is, -kan 間 is never used. Generally, there are no differences with how numbers are counted when used to refer to what year it is. However, it is worth noting that 2007 and 2009 are typically read as “nisenshichinen にせんしちねん” and “nisenkunen にせんくねん” respectively, although “nisen’nananenにせんななねん” and “nisenkyūnen にせんきゅうねん” respectively are also common. The same goes for 2017, 2019, etc.

Culture Note: In Japan, alongside the Western date system, there is traditional date system that utilizes the eras of emperors. The current era is called the Heisei Period (Heisei Jidai 平成時代).

-kanen ヶ年

The counter -kanen ヶ年 translates as “over…years” and is frequently employed in legislation and business settings. However, ikkanen 1ヶ年 is infrequently used because “one year” is typically too short for major projects to take place.

 1 いっかねん △ 2 にかねん 3 さんかねん 4 よんかねん
 5 ごかねん 6 ろっかねん 7 ななかねん 8 はちかねん

-nensei 年生

The counter -nensei 年生is used to indicate what grade in school someone is in.

 1 いちねんせい 2 にねんせい 3 さんねんせい 4 よねんせい
 5 ごねんせい 6 ろくねんせい 7 ななねんせい 8 はちねんせい
 9 きゅうねんせい 10 じゅうねんせい ? なんねんせい  

  It is important to note that after 6, the only time one would use this counter would be when referencing the American school system which is divided into 12 grade levels. Although the Japanese education system is also divided into 12 grades, what they’re called is not the same.

 Grade 1 Shōgakkō ichinen 小学校1年 Shō-Ichi 小1
 Grade 2 Shōgakkō ninen 小学校2年 Shō-ni 小2
 Grade 3 Shōgakkō san’nen 小学校3年 Shō-san 小3
 Grade 4 Shōgakkō yonen 小学校4年 Shō-yon 小4
 Grade 5 Shōgakkō gonen 小学校5年 Shō-go 小5
