The word for day in Japanese is nichi/hi (日). It is pronounced different ways depending on what you are speaking about. In this lesson we will cover a lot of information and the vocabulary you learn will be repeated in other lessons so don't worry if you find it hard to remember all the vocabulary in this lesson.
Today = kyou (今日)
Today (formal) = honjisu (本日)
Tomorrow = ashita/asu (明日)
Yesterday = kinou (昨日)
Days of week
Today is Monday = kyou wa getsuyoubi (今日は月曜日)
Yesterday was Saturday = kinou wa doyoubi datta
Tomorrow is Thursday = ashita wa mokuyoubi desu
The days of the month in Japanese are easy to remember if you know the numbers. Unlike other Japanese numbers there is only 1 way to say April, July and September.
Days of month
For each day of the month there is a different name. There is no general pattern so memorizing them is necessary. The numbers are usually written in Arabic numerals instead of kanji. The first 10 numbers follow a very unique pattern.
The other days of the month use the pronunciation nichi at the end except for a few exceptions.
Today is the 20th = kyou wa hatsuka desu (今日は２０日です)
Today is January 5th, Friday = kyou wa ichigatsu itsuka kin'youbi desu (今日は１月５日金曜日です)
Today in Japan they use the same method to date as they do in western cultures. On offical documentation they use a different way to track years, but we will learn that in another lesson. To say what year it is, say the number followed by the counter for year, which is nen (年).
Year 2008 = nisen hachi nen (2008年)
Year 1995 = sen kyuuhyaku kyuujuugo nen (1995年)
