Labor Day marks the unofficial end of which season in the United States?

Labor Day is celebrated on the first Monday in September and is often seen as the unofficial end of summer in the United States. This perception is influenced by various cultural practices, such as the end of school vacations and the transition to a new school year, as well as the start of fall activities. Many families traditionally plan last vacations or outdoor activities for Labor Day weekend, reinforcing the idea of marking the end of summer. The significance of Labor Day also ties into the acknowledgment of the contributions of workers and the labor movement, but its timing aligns with the seasonal changes occurring in September, transitioning from the warmth of summer to the cooler weather of fall.
