According to tradition, all first born individuals fast the morning of the first Seder in gratitude for being spared from the Tenth Plague. According to Jewish tradition, one need not fast if celebrating the completion of a book of rabbinic study. Even if you are not a first born, you are welcome to join Alan Zeman and Brad Greenspan’s completion of the Final Daf (page) of Sanhedrin, preceded by a brief morning service and Mourner’s Kaddish.
