Simchat Torah
On Simchat Torah (Hebrew: שמחת תורה ; "Joyous celebration of the Torah"), the order of weekly readings is completed, and the day is celebrated with various customs involving the Torah. The Torah is read at night – a unique occurrence, preceded by seven rounds of song and dance (hakafot, sing. hakafah; some communities have hakafot without subsequently reading the Torah.) During the hakafot, most or all of the synagogue's Torah scrolls are removed from the Holy Ark, and carried around the Bimah by members of the congregation.
On the day of Simchat Torah (in Judaism, day follows night), some communities repeat the seven rounds of song and dance to varying degrees, while in others the Torah scrolls are only carried around the Bimah (seven times) symbolically. Afterwards, many communities have the custom of calling every member of the congregation for an aliyah, which is accomplished by repeatedly re-reading the day's five aliyot. The process is often expedited by splitting the congregants into multiple rooms, to each of which a Torah is brought for the reading.
Following the regular aliyot, the honor of Hatan Torah ("Groom of the Torah") is given to a distinguished member of the congregation, who is called for an aliyah in which the remaining verses of the Torah are read, to complete that year's reading. Another member of the congregation is honored with Hatan Bereishit ("Groom of Genesis"), and receives an aliyah in which the first verses of the Torah, containing the creation account of Genesis, are read (a second copy of the Torah is usually used, so that the first need not be rolled all the way to the beginning while the congregants wait). Afterwards, the services proceed in the usual manner, with the maftir and haftarah for Simchat Torah.
