Here are key takeaways:

• Labor Day is an official paid state holiday in California under Government Code Section 6700, meaning state offices close and public schools are required to shut down under Education Code 37220.
• Post offices will be closed with no mail delivery, FedEx and UPS will not deliver, and Federal Reserve and commercial banks will be shut, though ATMs and digital banking remain available with delayed transaction posting.
• The first Labor Day was celebrated Sept. 5, 1882, in New York City, and Congress made it a national holiday on June 28, 1894, to honor American workers.
• For minimum wage workers, California’s wage was raised Jan. 1 by 40 cents to $16.90 an hour. Jan. 1, 2027 will see another increase.
• California’s average price for regular gasoline hit about $5.81 per gallon on Friday, Sept. 4 — roughly $1.67 above the national average and on track to set a Labor Day record.
• Trader Joe’s, Whole Foods, Safeway, Raley’s and most major Sacramento-area supermarkets will be open with regular or modified hours, but Costco and its gas stations will be closed Monday.
• The Sacramento Valley will see a cool holiday weekend with high temperatures in the 70s and low 80s.
• A beach hazard statement from the National Weather Service warns of swells up to 10 feet along much of the California coast through Monday morning.
• Anyone going to Yosemite for a Labor Day day trip or a quick overnighter should be prepared for crowds and plenty of traffic.
• Other quick escapes within two hours of Sacramento can be made to Murphys, San Francisco, Half Moon Bay or Napa.
