Pesach Sheni 2021 is observed on April 26 (14 Iyar).
Pesach Sheni means "Second Passover [Sacrifice]." It marks the day when someone who was unable to participate in the Passover offering in the proper time would observe the mitzvah exactly one month later.
The day represents the āsecond chanceā achieved by teshuvah, the power of repentance and āreturn.ā In the words of Rabbi Yosef Yitzchak of Lubavitch, āThe Second Passover means that itās never a ālost case.āā
