The word Shavuot (or Shavuos) means “weeks.” It marks the completion of the seven-week counting period between Passover and Shavuot.
The Torah was given by G‑d to the Jewish people on Mount Sinai on Shavuot more than 3,300 years ago. Every year on the holiday of Shavuot we renew our acceptance of G‑d’s gift, and G‑d “re-gives” the Torah.
The giving of the Torah was a far-reaching spiritual event—one that touched the essence of the Jewish soul for all times. Our sages have compared it to a wedding between G‑d and the Jewish people. Shavuot also means “oaths,” for on this day G‑d swore eternal devotion to us, and we in turn pledged everlasting loyalty to Him
NOTE: The Jewish calendar date begins at sundown of the night beforehand. Thus all holiday observances begin the night before, as listed. The exception to this rule is most fast days, which begin at dawn of the date listed (aside for Tisha b’Av and Yom Kippur which also begin the night before). Jewish calendar dates conclude at nightfall. For more information click here.
