Israel's diverse culture stems from the diversity of its population. Jews from diaspora communities around the world brought their cultural and religious traditions back with them, creating a melting pot of Jewish customs and beliefs. Arab influences are present in many cultural spheres, such as architecture, music, and cuisine. Israel is the only country in the world where life revolves around the Hebrew calendar. Work and school holidays are determined by the Jewish holidays, and the official day of rest is Saturday, the Jewish Sabbath.
