Tonight is Pesach Sheni, which occurs one month after Pesach.
The historical purpose of this day was for those who were unable to bring the Korban Pesach on the correct date—because they were then Tamei or too far from Yerushalayim—to have a second chance to do so.
Some have the Minhag to mark the day by eating Matzah.
Shouldn’t the matzah be eaten tomorrow night as it was done when the pesach was brought?
how much more did the price of matza go up since peach rishon?
