Yesterday was Purim for most of the Jews in Israel and the world.
Today is Jerusalem's turn to celebrate Purim.
Today is also when the Jewish community in Shushan, Iran marks the holiday.
Why? Well, it's a long story. If you really want to know, please see below.
I looked around for Purim costumes but then didn't have the nerve to photograph anyone from the front.
All the ultra-Orthodox men were out in their finest clothes today, including the round fur streimel hat. The little boy made a good fireman.
The girl with halo and wings . . . a black angel?
This old character in the shuk reminded me of a Viking warrior.
OK, the answer (from Wikipedia, based on Chabad):
Shushan Purim (the 15th day of Adar) is the day on which Jews in Jerusalem and Shushan (in Iran) celebrate Purim.
The Book of Esther explains that while the Jews in unwalled cities fought their enemies on the 13th of Adar and rested on the 14th, the Jews in the walled capital city of Shushan spent the 13th and 14th defeating their enemies, and rested on the 15th (Esther 9:20-22).
Although Mordecai and Esther decreed that only walled cities should celebrate Purim on the 15th, in commemoration of the battle in the walled city of Shushan, the Jewish sages noted that Jerusalem, the focus of Jewish life, lay in ruins during the events of the Book of Esther.
To make sure that a Persian city was not honored more than Jerusalem, they made the determination of which cities were walled by referring to ancient cities walled during the time of Joshua.
This allowed Jerusalem to be included on the basis of that criteria; paradoxically, they included Shushan as the exceptional case since the miracle occurred there, even though it did not have a wall in Joshua's time.
The Megillah is also read on the 15th in a number of other cities in Israel—such as Jaffa, Acre, Safed, Tiberias and Hebron—but only as a custom based on a doubt over whether these cities were walled or sufficiently walled during the time of Joshua.
These cities therefore celebrate Purim on the 14th, and the additional Megillah reading on the 15th is a stringency. Jews in these cities do not recite the blessings over the reading of the Megillah on the 15th.
