JD: The fast day of the 17th of Tammuz; now first of all explain that. What is this all about?
WM: Jimmy there are two main fast days in the Hebrew calendar. When I say main I mean they go the full 25 hours from just before sunset to just after sunset. Those are Yom Kippur the 10th day of the Hebrew month of Tishrei the Day of Atonement and the 9th of Av that usually comes out at the end of July or the beginning of August more or less which commemorates the destruction of the first and the second Temple.
