A tweet by Ivanka Trump @ivankatrump saying “I cannot believe that Theodore is eight months old today! Happy birthday little teddy bear!” with an admittedly cute picture of a child smiling. It has a reply from @blacknmild saying “this isn’t how birthdays work”
No, that’s not true. A birth week recurs yearly, not weekly.
A birth day is the day on which you were born, say Saturday, and you’ll have one of those every week.
A birth week is the number of the week in which you were born, say week 14, and it takes a year before it’s week 14 again. Same interval as a birth month.
A birth date only occurs once. It’ll never be July 4, 1981 ever again.
This is all very normal and logical. Beep boop.
