Everything seems to get more chaotic around the holidays - there's a rush at work and your calendar continues to fill up with events and parties to attend. Suddenly, it's the week before Christmas and you realize you forgot to find a gift. The good news is that you're not alone - plenty of us fall victim to last-minute gifting. But even if it's just a few days before the holidays, you can still find thoughtful gifts they'll appreciate - we have plenty of inspiration.

So, maybe you don't need to worry about finding the right gift, but you do need to worry about making sure that gift arrives on time. Luckily, if you like to shop online, many retailers have "buy by" dates that let you know when you need to purchase a product to guarantee it arrives by December 25.

Amazon is just one retailer that has released a detailed Prime member holiday delivery calendar to take the stress out of online shopping during the holidays.

It outlines what shipping options are available, and until when, to ensure delivery before Christmas for Prime members. Even if you aren't a Prime member, you can sign up for a 30-day free trial to take advantage of the holiday shipping options.

The following dates only apply to the contiguous US, though it's a good idea to double-check the delivery dates in your cart at checkout to be sure you'll get your gifts in time. You can always check out this chart for more information about Amazon Prime shipping benefits.
