I'm sorry for your loss.
If you mean that you are receiving widow's benefits on your husband's record, then your payments will probably normally arrive on either the 2nd, 3rd or 4th Wednesday of each month depending on your husband's birth date. If he was born in the first 10 days of a month you would be paid on the 2nd Wednesday of each month. If he was born between the 11th & 20th of a month, you would be paid on the 3rd Wednesday of the month, and if he was born after the 20th of a month you would be paid on the 4th Wednesday.
Your payment date could be different, though, depending on when you started receiving benefits and whether or not you also receive benefits on your own Social Security record (https://www.ssa.gov/OP_Home/handbook/handbook.01/handbook-0121.html).
