Purim Sameach!

Because this was a political plot, and the people as a nation were saved through good politics, it is more a national holiday than a religious holiday for the Jewish people. However, many Jews do go to the synagogue for a public reading of the Book of Esther, during which there is a tradition to use noisemakers to drown out the name of Haman anytime it is read. There are also gifts of food, gifts to charity, and a festive meal shared.
The parties
Because Esther delivered her people by throwing a party for positive politics, Purim is a festive holiday. Many wear masks and costumes to honor Esther, who disguised her religion so that it could be revealed well and at the right time, and to remind them that God “disguised” his presence behind unfolding politics.
