Pesach Sheni
Pesach Sheni is held on April 30. 14 Iyar- פסח שני - a Second Passover. This event in the third decade of the month April is annual.
In Temple times, Jews spent Passover in Jerusalem. On the afternoon before the holiday, they sacrificed a lamb or kid, referred to as the Korban Pesach (Passover Sacrifice) to eat during their Seder that evening. If someone was unable to participate in the Passover offering at the proper time, they would offer the sacrifice a month later. Pesach Sheni Means “Second Passover” (פסח שני).
As described in Numbers 9:9–13, a Jew may bring the Korban Pesach on Pesach Sheni if s/he was ritually impure due to contact with a dead body or was on a "distant journey".
