This is one of the newest holidays on the Jewish calendar, Yom Yerushalayim in Hebrew. On this day 45 years ago (June 6, 1967 on the Western calendar), the eastern half of Jerusalem was captured by the Israelis, at the height of the Six Day War. This means that Israel has now ruled a united Jerusalem, for almost as long as Britain and Jordan (put together) ruled over east Jerusalem. Mazeltov!
Here is a video that plays footage from that day, and the Hebrew language announcement of the liberation. And check out the link afterwards for the story of one Israeli who was there.
For me today marks two anniversaries, but nothing as momentous as the reunification of a city. One month ago on this day, my job in Connecticut ended, and on this day in 2006, I moved out of Florida.
