Second Passover

The "Second Passover" (Pesach Sheni) on the 14th of Iyar in the Hebrew Calendar is mentioned in the Hebrew Bible (Numbers9:6–13) as a make-up day for people who were unable to offer the pesach sacrifice at the appropriate time due to ritual impurity or distance from Jerusalem. Just as on the first Pesach night, breaking bones from the second Paschal offering (Numbers 9:12) or leaving meat over until morning (Numbers 9:12) is prohibited.

Today, Pesach Sheni on the 14th of Iyar has the status of a very minor holiday (so much so that many of the Jewish people have never even heard of it, and it essentially does not exist outside of Orthodox and traditional Conservative Judaism). There are not really any special prayers or observances that are considered Jewish law. The only change in the liturgy is that in some communities Tachanun, a penitential prayer omitted on holidays, is not said. There is a custom, though not Jewish law, to eat just one piece of matzo on that night
