Labor Day 2025: Date, Meaning, and Why It’s Known as the Last Weekend of Summer

Labor Day has long been considered the unofficial farewell to summer in the United States. Marked by parades, barbecues, and a well-earned day off for many workers, this federal holiday is more than just a seasonal marker—it’s a celebration of labor rights and the contributions of American workers.

In 2025, Labor Day falls on Monday, September 1, aligning with both its historical roots and its role as a seasonal turning point. For many families, it’s the final long weekend before school resumes, while for others it signals the beginning of meteorological fall.

When is Labor Day 2025 and Why Does It Matter?

Labor Day 2025 will be observed on Monday, September 1 across the United States. The date always falls on the first Monday of September, ensuring a three-day weekend for most Americans. This tradition was established in 1894 when Congress officially recognized Labor Day as a federal holiday to honor the social and economic achievements of workers.

The holiday’s timing plays a symbolic role in American culture. For meteorologists, September 1 marks the start of meteorological fall, defined by the three-month block of September, October, and November. For those who follow the astronomical calendar, fall begins later, with the autumnal equinox—set for September 22, 2025—when daylight and nighttime hours are nearly equal.

Is Labor Day the End of Summer?

While summer weather can linger well into September, Labor Day weekend is traditionally seen as the last major holiday of summer. The timing coincides with the end of vacation season, the return to school, and the winding down of warm-weather activities.

Culturally, the holiday has also been tied to fashion traditions—most notably the old rule about not wearing white after Labor Day. Though largely outdated today, the saying still gets mentioned in lifestyle conversations every year.

From a seasonal standpoint:

• Meteorological summer runs from June 1 to August 31.

• Astronomical summer ends at the September equinox (Sept. 22 in 2025).

So while Labor Day may not be the scientific end of summer, it marks a cultural shift toward fall activities, from football games to pumpkin-flavored everything.

Historical Significance and Modern Celebrations

Labor Day’s roots trace back to the late 19th century, a time when labor unions were growing in influence and advocating for better working conditions, fair pay, and reasonable hours. The first Labor Day parade took place in New York City in 1882, organized by the Central Labor Union.

Today, the holiday is celebrated with:

• Community parades showcasing local organizations and workers.

• Cookouts and picnics as a way to enjoy one final summer gathering.

• Retail sales events, which have become a major part of the weekend for businesses and shoppers alike.

For many, it’s also a time to reflect on the labor movement’s achievements and ongoing worker rights discussions in today’s economy.

Key Fall 2025 Dates After Labor Day

Once Labor Day passes, the fall season quickly fills with significant cultural and religious observances:

• Rosh Hashanah: Tuesday, September 23

• Yom Kippur: Thursday, October 2

• Columbus Day: Monday, October 13

• Halloween: Friday, October 31
