Days of the month, dates
In Japanese, the days of the month are a bit more complex than the numbers (listed above).
For example, you might think that as it says « ichigatsu » for January (litterally : Month one), you can say « ichinichi » (day one) to say the 1st of the month. Well, almost. Ichinichi means one day, but in the duration of one day. The 1st of the month is « Tsuitachi ».
Here are the special days of the month (others follow the same rules as absolute numbers)
1st : tsuitachi
2nd : futsuka
3rd : mika
4th : yoka
5th : itsuka
6th : muika
7th : nanoka
8th : youka
9th : kokonoka
10th : touka
14th : juuyoka
20th : hastuka
24th : nijuuyoka
For the years, it’s very easy (as soon as you keep with the western calendar, because the Japanese calendar is a bit more tricky for foreigners anaware of the history of Japan). Just use the absolute number and add « nen » (année) to specify it’s a date.
Ex : 1982 : Sen Kyuhyaku Hachijuu ni nen.
For the age, you say the number and add « sai » :
1 year old : isai
2 years old : nisai
3 years old : sansai
It’s very easy and goes on this way. If you don’t know the exact age, use « goro » to say « about » :
About 5 years old : gosai goro.
Only exception would be :
20 years old : Hatachi
30 years old : Misoshi
Nanji desu ka : What time is it ? So…
It’s one o clock : ichi ji
…2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 o’clock : ni ji, san ji, yo ji, go ji, roku ji, shichi ji, hachi ji, ku ji, juu ji, juu ichi ji, juu ni ji.
Midnight : rei ji
1 past 5 minutes : ichi ji go fun
…past 10 min, 15 min, 20 min, 25 min… and a half : juu pun, jugo fun, nijuu pun, nijuu go fun, … sanjuu pun
…twenty five to, twenty to, fiveteen to, ten to, five to two : Niji nijugofun mae, niji nijupun mae, niji juugo fun mae, ni ji juupun mae, ni ji go fun mae.
4 in the morning : gozen no yoji
4 in the afternoon : gogo no yoji
When you want to count, you’ll find that Japanese is the most complex and horrible languages of all in that matter. There are so many way to count stuff, based on the nature of what your are counting : long stuff, flat stuff, mechanical stuff, plane, house, people, round stuff, big stuff, food…so lets focus on two of them
