Purim is a two day event beginning at sundown on the fourteenth day of Adar, the twelve month of the Jewish calendar.
Every race and religion has their solemn and their festive holidays. Purim is the most festive of the Jewish Holidays. Children dress in costumes and people give gifts. Usually solemn synagogues are turned into festive arenas. Children shake noise makers called "Graggers".
The festive holiday centers around Queen Esther, King Ahasuerus (or Achashverosh), Mordecahi and Haman. The event took place in the Persian Empire in the fifth century, B.C. It is a celebration of a major victory against oppression of the Jews at that time.
