Pesach Sheni

Pesach Sheni (Hebrew: שני פסח, trans. Second Passover) occurs every year on 14 Iyar. This is exactly one month after 14 Nisan, the day before Passover, which was the day prescribed for bringing the Korban Pesach (“Paschal offering”, i.e. Passover lamb) in anticipation of that holiday.[1] As described in the source text for this mitzvah (Numbers 9:1-14), the Israelites were about to celebrate Passover one year after leaving Egypt.
