Pesach Sheni is this week, on Wednesday. The Sefer Hatodaah (as 
translated by RnTK's father, Rav Bulman zt"l) writes: "Some have the 
custom of eating some left-over matzah from Pesach, as a memorial to 
the Pesach sacrifice which was eaten together with matzot."

Does anyone know, according to this minhag, when would the matza be 
eaten? On Wednesday afternoon, corresponding to when the Pesach Sheni 
is shechted, or on Wednesday night, corresponding to when the Pesach 
Sheni is eaten?

Thanks!
