1) Shushan Purim

In Jerusalem, Purim is celebrated on 15 Adar, a day later than everywhere else (celebrated on March 11, 2009). This separate date, known as Shushan Purim, is based on Esther 9:20-22, which says the "walled cities" did not achieve victory until that day. Judaism interprets this as the cities that were walled at the time of Joshua, and one city that definitely fits that description is Jerusalem. 

In the case of the first Gulf War between the U.S. led coalition against Iraq, the Presidential order to strike Iraq was likely given sometime during the hours of Purim--March 18, 2003, or Shushan Purim--March 19, 2003.  President Bush's Address to the Nation occurred the evening of March 19, 2003.  We may find that when the West confronts the second and higher horn--Iran, that the war will begin at or near a Festival date.  Daniel (8:3) said, "Then I lifted up mine eyes, and saw, and, behold, there stood before the river a [Islamic] ram which had two horns [Iraq & Iran]: and the two horns were high [notable]; but one [Iran] was higher than the other [larger, even more formidable], and the higher [Iran] came up last [to be confronted last].

2) Purim Katan

Purim Katan is the lesser Purim—the 14th day of the Hebrew month of Adar I.  Purim Katan occurs during a leap year, when there are two months of Adar (Adar I & Adar II).  Although the Festival of Purim actually arrives one month later, Purim Katan is like a mirror reflection of Purim.  Purim Katan has some of the characteristics of a festive day, and is akin to preparation for Purim.  In fact, starting at Purim Katan, Jews begin to contemplate the meaning of Purim that is just four weeks away, and the great deliverance of Israel that it marks.  Some communities also observe a “Purim Katan” on the anniversary of any day when their community was saved from a catastrophe, destruction, evil or oppression.
