Tisha b'Av. The ninth day of the month of Av.
The date in the Hebrew ritual calendar is the 9th day in the month of Av, which is the meaning of the words "Tisha b'Av." The commemoration is named by its date just as the "Fourth of July" is named by its date. In the Gregorian (Western) calendar, Tisha B'av always occurs between mid-July and mid-August.

Tisha means 'strong will' in Swahili.
The AV valves open when the blood pressure exerted on their atrial side is greater then on the ventricle side. This happens when blood returning to the heart fills the atria and puts pressure against the valve. Note : When heart is completely relaxed, the AV valve flaps hang limply into the ventricle chamber (open) allowing blood from the atria to flow through them directly to the ventricle. Thus, it is the result of ventricle contraction which closes the AV valves and moves them from their resting state (open).
