Easy Guide: Learn Days in Japanese & Days of the Month

Yo, B!

Looking to learn days in Japanese?

And wondering why I called you “B?”  Don’t worry. Just keep “yo b” in mind as you read this guide. In this guide, you’ll learn days in Japanese — of the week, of the month, and other relevant words. 

Here’s a quick preview and I’ll explain it all below.

  • Monday – 月曜日
  • Tuesday – 火曜日
  • Wednesday – 水曜日
  • Thursday – 木曜日
  • Friday – 金曜日
  • Saturday- 土曜日
  • Sunday – 日曜日

Let’s go.

Days of the Week in Japanese

The good news? All days of the week in Japanese follow a simple pattern.

They all contain “youbi” or “曜日” in Japanese.

Which sounds like “yo B.” Get it? So, if you’re a beginner and if you hear a “youbi,” that’s how you know you heard some day of the week in Japanese.

So, here’s the list of the days of the week in Japanese.

  • Monday – 月曜日 – Getsuyoubi
  • Tuesday – 火曜日 – Kayoubi
  • Wednesday – 水曜日 – Suiyoubi
  • Thursday – 木曜日 – Mokuyoubi
  • Friday – 金曜日 – Kinyoubi
  • Saturday– 土曜日 – Doyoubi
  • Sunday – 日曜日 – Nichiyoubi

Now you know days from Monday to Sunday.

As a bonus, here are two more words you need to know. Because the weekend is part of the week too.

  • Saturday & Sunday (or the weekend) – 土日 – Donichi –
    • If you’re clever, you’ll notice that “donichi” is just a combination of the first kanji from Saturday (土 – do) and Sunday (日 – nichi).
  • Weekend – 週末 – Shuumatsu

Okay, now you know the days of the week. What’s next? These bonus words.

Bonus Words for Days in Japanese 

Now, aside from Monday and Tuesday, there are other Japanese words you should know.

Like, “today,” “tomorrow” and “the day after tomorrow.”

Here they are.

  • today – 今日 – kyou
  • tomorrow – 明日 – ashita
  • yesterday – 昨日 – kinou
  • the day before yesterday – おととい – ototoi
  • the day after tomorrow – あさって – asatte
  • the other day – 先日 – senjitsu
  • weekday – 平日 – heijitsu
  • holiday (day off) – 休日 – kyuujitsu
    • Yasumi is also acceptable
  • day off – 休み – yasumi
  • every day – 毎日 – mainichi
  • someday – いつか – itsuka
    • As in, “someday, I will learn Japanese.”
  • one day – ある日 – aru hi
    • As in, “One day, I woke up and decided to learn Japanese.”
  • all day – 一日中 – ichnichijuu

So now you know the days in Japanese plus some relevant vocabulary.

Now, let’s move onto the days of the month in Japanese.

Days of the Month in Japanese

Now, onto days of the month in Japanese. Is it as easy as the first, the second or 15th of the month?

Well…

If you already know Japanese numbers

…you’re sort of almost there.

You’re very close to mastering the days of the month.

There are variations that you need to memorize.

For example, the 1st of a month isn’t called “the first” or “ichi” but rather “tsuitachi.” And the 10th of the month doesn’t use “juu” which means “10.” It’s “tooka.”

But when you get to the 10s and 20s, most of them follow an easy formula, which I reveal below.

So, take a look below at the Japanese days of the month.

1ついたちTsuitachi11じゅういちにちJuuichi nichi21にじゅういちにちnijuuichi nichi
2ふつかFutsuka12じゅうににちjuuni nichi22にじゅうににちnijuuni nichi
3みっかMikka13じゅうさんにちjuusan nichi23にじゅうさんにちnijuusan nichi
4よっかYokka14じゅうよっかjuuyokka24にじゅうよっかnijuuyokka
5いつかItsuka15じゅうごにちjuugo nichi25にじゅうごにちnijuugo nichi
6むいかMuika16じゅうろくにちjuuroku nichi26にじゅうろくにちnijuuroku nichi
7なのかNanoka17じゅうしちにちjuushichi nichi27にじゅうしちにちnijuushichi nichi
8ようかYouka18じゅうはちにちjuuhachi nichi28にじゅうはちにちnijuuhachi nichi
9ここのかKokonoka19じゅうくにちjuuku nichi29にじゅうくにちnijuuku nichi
10とおかTooka20はつかhatsuka30さんじゅうにちsanjuu nichi
31さんじゅういちにちsanjuuichi nichi

You will need to memorize the blue ones. Mostly from 1 to 10. But 11 and up are fairly easy.

From 11 and up, most follow this formula:

  • [number in japanese] + [nichi]
  • 11 is juuichi + nichi = juuichi ichi
  • 12 is juuni + nichi = juuni nichi
  • 25 is nijuugo + nichi = nijuugo nichi

The only ones that don’t follow the formula and need memorization are:

  • 14 – juuyokka
  • 20 – hatsuka
  • 24 – nijuuyokka

So, learning the days of the month in Japanese is just a matter of memorization. Or reviewing a lot. It’s not hard. But with enough reviews and glances you’ll get it.
