Alleviate your holiday shopping stress with this handy shipping deadline cheat sheet. It's all about organization (or the willingness to shell out extra for speedy delivery rates).
Straight from the source, cut off dates for UPS Domestic & International:
If you're shipping UPS, you have until the 23rd to use Next Day Air. For more details, you can view and print their holiday schedule here. Or you can print the format with more room for taking notes here.
For FedEx Express, you have until the 23rd. However, if you want to save some dough, better get it in by the 17th (or 13th, if you're shipping to or from Hawaii or Alaska) for the ground rate.
P.S. If you're really desperate, according to the cart you can do same-day shipping on the 25th. But I can only imagine what that costs...
