What minor Passover-related observance falls on the 14th day of Iyar?

The minor Passover-related observance on the 14th day of Iyar is Pesach Sheni, or “Second Passover.”

The Torah introduces Pesach Sheni after some Israelites were unable to offer the paschal sacrifice at its appointed time because they were ritually impure or away from the community. They appealed to Moses, and a special opportunity was established one month later, on 14 Iyar. In its original biblical setting, the observance involved the Passover offering and unleavened bread.

Today, the Temple no longer stands, so the sacrifice cannot be performed. Some Jewish communities mark the date by eating matzo, omitting certain penitential prayers, or holding a meal with Passover-inspired elements. Hasidic groups may conduct a small seder-like gathering, though practices vary.

Pesach Sheni is not the same as Rosh Chodesh, the beginning of a Hebrew month, or Lag BaOmer, which falls later in Iyar. Its enduring theme is often described as a second chance to participate in a sacred obligation.
