The Three Pilgrimage Festivals or Three Pilgrim Festivals, also known by their Hebrew name Shalosh Regalim (Hebrew: שלוש רגלים, romanized: šālōš rəgālīm, or חַגִּים, ḥaggīm), are three major festivals in Judaism—two in spring; Passover, 49 days later Shavuot (literally 'weeks', or Pentecost, from the Greek); and in autumn Sukkot ('tabernacles', 'tents' or 'booths')—when all Israelites who were able were expected to make a pilgrimage to the Temple in Jerusalem as commanded by the Torah. In Jerusalem, they would participate in festivities and ritual worship in conjunction with the services of the kohanim (priests) at the Temple.
All three coincide with important harvest times in the Land of Israel: Passover with the barley harvest, Shavuot with the harvesting of the wheat, and the eighth day of Sukkot marks the conclusion of the fruit harvest.
