I learnt from my teacher that the days of the month from 1 to 10 use kun and irregular pronunciations:
一日: ついたち (irregular)
二日: ふつか (kun)
三日: みっか (kun)
...
十日: とおか (kun)
But for words like 一日目, 二日間 and 三日間後, what would be the correct pronunciation and the rules for this? I heard 一日目 is いちにちめ and 三日間後 is みっかかんあと. Is this correct?
