Just realized the stock market closes on Labor Day—both NYSE and Nasdaq shut down for the whole day. If you're wondering whether markets are closed on Labor Day, the answer's yes, they always are. This year it fell on September 1, 2025, so trading didn't resume until Tuesday morning.

Got me thinking about why though. Turns out Labor Day started way back in 1882 with this huge parade in NYC organized by the Central Labor Union. Workers fighting for better conditions, fair pay, decent hours—the whole movement. Then in 1894 after the Pullman Strike got really ugly, President Cleveland made it official federal holiday legislation. Pretty wild how it became this symbol of workers' rights.

Bond markets shut down too on Labor Day—SIFMA marks it as a full market holiday, so Treasury and corporate bonds aren't trading either. Everyone gets the same day off across the financial sector.

Honestly, it's a good reminder that markets being closed on Labor Day isn't random. It's about honoring what workers built. Some people use the day to reflect on labor movements, others just chill with family or hit the beach before fall kicks in. You can also support local businesses, volunteer for workers' advocacy groups—basically celebrate the actual spirit of it instead of just watching the market pause.

Next one to watch out for is Thanksgiving in November. Definitely helps to know when markets are closed so you don't get caught off guard with your trades.
