Change Social Security check scheduling to a date of the month instead of e.g. "2nd Wednesday" of month

Social Security checks are currently issued on the occurrence of specific days. For example, they might be issued on the first Wednesday of the month, the 2nd Wednesday, etc, This results in checks arriving five weeks apart numerous times each year, making it difficult for seniors on tight budgets. Change the scheduling so that checks arrive on specific dates, for example the seventh day of each month. This would cause more uniform spacing between checks, without changing the total annual amount paid.
