Each Torah portion consists of two to six chapters to be read during the week. There are 54 weekly portions or
parashot. Torah reading mostly follows an annual cycle beginning and ending on the Jewish holiday of
Simchat Torah, with the divisions corresponding to the
lunisolar Hebrew calendar, which contains up to 55 weeks, the exact number varying between
leap years and regular years. There are some deviations to the cyclic regularity noted above, all related to the week of
Passover and the week of
Sukkot. For both holidays, the first day of the holiday may fall on a Sabbath, in which case the Torah reading consists of a special portion relevant to the holiday rather than a portion in the normal cyclical sequence. When either holiday does
not begin on a Sabbath, yet a different 'out of cycle' portion is read on the Sabbath within the holiday week. Immediately following Sukkot is the holiday of
Shemini Atzeret. In Israel, this holiday coincides with Simchat Torah; in the
Jewish Diaspora, Simchat Torah is celebrated on the day following Shemini Atzeret. If Shemini Atzeret falls on a Sabbath, in the Diaspora a special 'out of cycle' Torah reading is inserted for that day. The final
parashah, ''
V'Zot HaBerachah'', is always read on Simchat Torah. Apart from this "immovable" final portion, there can be up to 53 weeks available for the other 53 portions. In years with fewer than 53 available weeks, some readings are combined to fit into the needed number of weekly readings. The annual completion of the Torah readings on Simchat Torah, translating to "Rejoicing of the Torah", is marked by Jewish communities around the world. ==Name==
