Tachanun
Question
Sha’arei Teshuvah, Orach Chayim 131:19
Tachanun is not recited on the 14th of Iyar משום Pesach Sheni.
My question is: why is it recited on the 15th, since eating the offering is on the night of the 15th?
Answer
Maybe because Tachanun is recited during the day. And besides, with sacrificial offerings, the night follows the day.
