מועדים וימי זכרון
Th Jewish calendar has two kinds of celebrations:
The Moadim—Appointed times—are presented and explained on the text of the Torah more than once, with the details of their offerings. They are given to us as “perpetual law,” something we must accomplish every year for all generations.
The Yemei Zikaron—Days of Remembrance—are festivities that marked important moments in the history of the People of Israel.
