Pesach, also known as Passover, is a significant Jewish holiday that commemorates the liberation of the Israelites from slavery in Egypt. It is celebrated in the spring, lasting for eight days in most Jewish communities. The holiday begins with a special meal called the Seder, where families gather to retell the story of the Exodus and enjoy symbolic foods. During Pesach, observant Jews refrain from eating leavened bread, known as chametz, and instead consume unleavened bread called matzah. This practice symbolizes the haste with which the Israelites left Egypt, not having time for their bread to rise. The holiday emphasizes themes of freedom, redemption, and the importance of remembering one's history.
