Entering the New Month of Adar 5783
In lieu of the communal sin offering being brought up to the mizbeach in the Beis HaMikdash, a day of repentance, immediately preceding the New Month was established: this is called Yom Kippur Katan. And, the observance is on the 29th of the preceding month, in preparation of the renewal of the soul, that we hope to foster, through prayer, fasting, and repentance.
