Santa's elves aren't the only ones keeping busy right now. It is peak season for mailing and shipping services. The holidays bring a huge influx of business as people try to send their loved ones a gift across the globe.

Because so many people are trying to send things in the mail, services like Amazon, FedEx, UPS and the U.S. Postal Service have to flex their usual shipping schedules and cut-off dates just a bit. (For example, a package that usually only takes a few days to get somewhere may need to be sent out a week in advance this time of year.)

Don't sweat it if you haven't send everything out just yet - we have you covered. Here are the most important dates and deadlines you should know right now if you still have some shipping to do.

    Amazon

    Amazon has several different shipping options. Their cut-off dates are based on your package arriving by the end of the day December 24th. The closest deadline is for those who plan to ship free and it varies from there. There are different shipping deadlines for places like Hawaii, Alaska and Puerto Rico. You can see all the shipping deadlines here.

    UPS

    UPS says they flex their delivery schedule a bit around this time of year to deal with increased demand so your usual shipping habits will also need to shift a bit, too. Some packages will need an additional day to get to their destination. The first delivery cut-off date is as early as December 18th. For a full holiday shipping schedule, click here.
