Reviewing vocabulary today, I wondered about the difference between
As usual, I found some helpful info online:
yuu, yuugata 夕 - 5pm to 7pm
ban 晩 - 7pm to 10pm
yoru 夜 - 10pm onwards
Also, ban is usually used in combination (konban), not by itself.
Also yuube specifically means yesterday's evening. (Ah, or apparently as an evening event, like soiree.)
(I also came across a reference to "ushimitsu-doki", which is 2-3 am. Interesting!)
