The history of Judaism is full of incredible stories, which, according to the Hebrew Bible, are important for Jews of all generations to remember. Because the purpose of most of the holidays and festivals in Judaism is to recall God's work in history, they are one of the most important aspects in the religion of Judaism.
Observing holidays and festivals also has important social outcomes. They help to keep tradition alive, contribute to a sense of community and belonging, and ensure regular reflection and celebration. The most important Jewish holy days are the Sabbath, the three pilgrimage festivals (Passover, Shavuot, and Sukkot) and the two High Holy Days (Rosh Hashanah and Yom Kippur).
