Why five and not four?
Four weeks account for exactly 28 days, so every month is guaranteed four of each weekday. September 2024 runs 30 days, which leaves 2 days beyond four whole weeks, falling on Sunday and Monday. Monday is among them, which is why it appears a fifth time, on September 30.
Five Mondays and the payroll question
A month with five Mondays matters to anyone paid weekly or fortnightly on that day, because it produces an extra pay date inside the same calendar month. In 2024 that happens in January, April, July, September, December, so September 2024 is one of 5 months this year.
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.
