After my dad died (1969) we got our checks on the 3rd.
I know, ‘cuz that’s when my “step-dad” showed up to steal them.
He disappear completely when I turned 18...and the checks stopped.
What about leap years?... : )
BTW I looked up the SSN check I should receive when I retire, which is many years away, and it shows at 66 years 8 months a bit more then $2,000/month and at 70 it would be about $2,500
I add from my savings and I should be doing ok. I will try to wait so I get that extra $500 a month.
