It may have been a Sunday, but several post offices across the country were working overtime for Santa — including one right in Rochester.

“What we want to do is help people get their holiday packages and letters on the way,” USPS spokesperson Karen Mazurkiewicz said.

Between Thanksgiving and New Year’s Day, 10 million packages will be delivered across the Western New York area. So to help with the workload and busy Christmas shoppers, many United States Postal Service locations are offering extended hours Saturday and yes, even Sunday.

The area’s main post office on Jefferson Road will be open from 10 a.m. until 3 p.m. every Sunday until Christmas.

“I like it. A lot of the times I work, so I’m not able to go to the post office when they’re open," Henrietta resident Lindsay Lagon said. "I’m mailing some Christmas cookies, actually. So I’m able to get them out before the weather down south gets too warm.”

And deadlines for guaranteed Christmas delivery are fast approaching: December 14 for ground delivery, December 20 for priority mail and letters, and December 22 for priority mail express.

You can check out all the extended hours on their website, but you can also see where self-service kiosks are located to ship packages yourself and purchase and print shipping labels right from your home computer.

“Sometimes picking the gift is the hardest part about holiday mailing," Mazurkiewicz said. "But once you decide what you’re going to get and get it, the real joy is getting it off your plate and over to us so we can deliver it."
