(Hebrew: / Spelling: Elul, Ellul, Elull / Other Names: )
Elul is the twelfth month in the Jewish Calendar and the 6th according to some calculations. It is a month of mercy and repentance when the Jewish nation prepares themselves for the high holidays.
The month of Elul is a month of repentance, where Hashem gives the Jewish nation a chance to repent.
After the breaking of the first Luchos, Moshe once again ascended to heaven on the first day of Elul. He remainder there for 40 days and forty nights, comprising the entire month of Elul and the first ten days of Tishri, praying the that the Jews be forgiven for the the sin of the Golden Calf. On Yom Kipor Hashem revealed to him that he had forgiven the Jewish Nation and Moshe descended with the Secound Luchos.
Sefaradim recite Selichot during the entire month of Elul and up to Yom Kippor. There are those that begin on the first day of Rosh Chodesh Elul and there are those that start on the second day of Rosh Chodesh. It is customary by the Sephardim to recite the Selichot very early in the morning.
Askinazim do not start reciting the Selichot until the week of Rosh Hashanah. On the Motzai Shabbos preceding Rosh Hashana, the first Selichot is recited in the middle of the night. From then until Yom Kippor the Slichot are recited in the morning before Shachiris. If Rosh Hashana falls out Monday or Tuesday then Slichot are started a week before.
Blowing the Shofar
Each morning during the month of Elul aside from Erev Rosh Hashana the Shofar is blown at the end of the Shachris services. There are those that begin blowing the Shofar on the first day of Rosh Chodesh Elul and others on the second.
Most communities only blow the Shofar TSR"T but there are others that blow a full TSR"T TS"T TR"T.
There are even some communities that do an additional blowing of the Shofar each night after the Mariv prayers.
