The reading of the book of Esther, called the Megillah, is at the center of modern Purim observance. It is traditionally read in the evening and again during the day.
The congregation participates enthusiastically. When Haman's name is read, people commonly make noise to blot out the name of the villain.
Food is sent to friends in a practice called mishloach manot. Gifts are also given to people in need, known as matanot la'evyonim.
A festive Purim meal brings family and friends together. The celebration is known for an unusually cheerful and playful atmosphere.
Costumes have also become a familiar part of Purim in many communities. Children and adults may dress as characters from Esther or in other costumes. Humorous plays called Purim spiels are another popular tradition.
These later customs surround a core that reaches back to Esther itself: joy, feasting, sharing with others and remembering deliverance.
