If you want your holiday package to arrive on time, here are the deadlines to know

It's the most wonderful time of the year, and while the holiday season may have snuck up on some of us, that doesn't mean your last-minute shipping woes need to sneak up on you as well.

Retailers across the U.S. are urging customers to finish their holiday shopping early this year, as supply chain issues and other shortages are posing a concern for many hot products on this year's shopping lists.

The U.S. Postal Service, FedEx and UPS have all released their deadlines for holiday packages and cards to arrive by December 25 — telling customers to mail their holiday packages earlier rather than later.

"We are ready and positioned to have a successful peak season," said Postmaster General Louis DeJoy in a statement last week. "Americans should feel confident sending their holiday cards, mail and packages with the Postal Service. There is a spirit of excitement throughout [USPS] and our entire team is ready to deliver the holidays for the nation."

Here's a list of the major shipping deadlines for each of the services — AKA the last possible day for you to procrastinate on sending those packages:
