Why four and not five?
Four weeks account for exactly 28 days, so every month is guaranteed four of each weekday. September 2026 runs 30 days, which leaves 2 days beyond four whole weeks, falling on Tuesday and Wednesday. Monday is not among them, so the count stays at four.
When Monday does get a fifth
2026 has 4 months with five Mondays: March, June, August, November. September 2026 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.
