September 2025 begins on a Monday and ends on a Tuesday: 30 days, 22 weekdays and 8 weekend days. Mondays and Tuesdays come round five times this month.
September starts the academic year and, for many teams, the real planning year. Week numbers climb into the high thirties — seeing them printed avoids the "which week are we in" exchange.

Working days in September 2025
September 2025 has 22 weekdays. Nationwide public holidays that land on one of them take it back, so the count depends on the country:

| United States | Labor Day (Monday 1) | 21 |
| United Kingdom | none | 22 |
| Canada | Labour Day (Monday 1), National Day for Truth and Reconciliation (Tuesday 30) | 20 |
| Australia | none | 22 |
Regional holidays — a state day in the US, Scotland's own bank holidays — are not subtracted. The linked pages carry the month-by-month table for the whole of 2025.

United States holidays are shown because that is what the generator opens with. The holiday country is a separate setting from the calendar language, so you can mark United Kingdom, Canadian or Australian holidays instead, choose from over two hundred other countries, or turn the holiday layer off entirely.
