Why four and not five?
Four weeks account for exactly 28 days, so every month is guaranteed four of each weekday. September 2029 runs 30 days, which leaves 2 days beyond four whole weeks, falling on Saturday and Sunday. Monday is not among them, so the count stays at four.
When Monday does get a fifth
2029 has 5 months with five Mondays: January, April, July, October, December. September 2029 is not one of them, so anyone paid weekly on a Monday gets the usual four pay dates rather than a fifth.
Mondays in September across other years
The same month shifts forward a weekday each year, and two across a leap year, so the answer moves with it.
