Halocho #1638 - Why do we blow the Shofar during Elul

Today - Sunday - is the second day of Rosh Chodesh Elul; the first day of the month of Elul.

The coming 40 days, starting today, correspond to the 40 days that Moshe spent on Har Sinai, to receive the 2nd set of Luchot (Tablets with the 10 commandments written on them).

Moshe came down with these Luchot on Yom Kippur. Ever since, these 40 days are especially auspicious for Teshuva; repenting.

The custom is to blow the Shofar after Shacharit (the morning prayers) from today, until Friday, 27 Elul (11 September), as a reminder to start improving one's Torah observance and to repent for past misdeeds.

On Erev Rosh Hashana, the Shofar is not blown, in order to create a division between the custom of blowing Shofar in Elul and the Torah-commandment to blow Shofar on Rosh Hashana.

Starting tomorrow - Monday - Sefardim say Selichot before Shacharit and continue doing so the entire month of Elul until Erev Yom Kippur.
