1.
eight days
A duration of eight days.
八日 uses native Japanese counting and means both "eight days" (duration) and "the 8th" (date).
Usage
- Duration: 八日かかる (takes eight days)
- Date: 八日に届く (arrives on the 8th)
- 八日間: eight-day period (adds 〜間 for explicit duration)
Days 11-31 use the regular 十一日 pattern, except 十四日, 二十日 and 二十四日. The 8th's special reading does not carry over: the 18th is 十八日 and the 28th 二十八日.
