If the claimant filed for Social Security benefits before May 1, 1997, his payments usually are dated and delivered on the 3rd of the month following the month for which the payment is due. For example, payments for January are delivered on February 3rd. If the 3rd of the month is a Saturday, Sunday or Federal holiday, your payments are dated and delivered on the first day before the 3rd of the month which is not a Saturday, Sunday or Federal holiday. For example, if the 3rd is a Saturday or Sunday, payments are delivered on the preceding Friday. If the claimant filed for Social Security benefits May 1, 1997, or later, he will be assigned one of three new payment days based on the date of birth of the insured person.
