Planning around September 2025
September is the transition from summer to fall. The school year is underway across the country, and Labor Day weekend is widely treated as the unofficial end of summer.
- Labor Day always falls on the first Monday of September, creating a three-day weekend — plan travel and closures around it.
- Many organizations return to full schedules after Labor Day, making it a natural reset point for fourth-quarter planning.
