Christmas Dinner Planner 2026: Cooking Timeline for Fri., Dec. 25

Christmas Day 2026 is Friday, Dec. 25, according to the U.S. Office of Personnel Management (OPM), and a 20 lb frozen turkey needs to go into the refrigerator by Sunday, Dec. 20. That date is computed from University of Wyoming Extension’s rule of 24 hours of thawing per 4 pounds. The count-back below covers turkeys from 8 to 24 lb, the safe temperature for each Christmas main and a printable with a shopping list. For the date itself, see when is Christmas Day.

Extension services publish the U.S. Department of Agriculture (USDA) food-safety figures; the federal pages themselves blocked automated reading when this story was checked on Nov. 15, 2026. Each number below names the extension service it comes from.

When to start thawing a Christmas turkey

University of Wyoming Extension, in “Let’s talk turkey” (MP-135, October 2018), says to allow 24 hours per 4 pounds of a whole turkey in the refrigerator. Our Thanksgiving thaw guide works from the USDA range of 4 to 5 pounds per day; the 4 lb figure used here gives the earlier, safer start. The hours and dates are computed from Wyoming’s rule.

Turkey weight	Fridge thaw time	Start thawing by	Cold-water thaw time
8 lb	48 hours (2 days)	Wed., Dec. 23	4 hours
12 lb	72 hours (3 days)	Tue., Dec. 22	6 hours
16 lb	96 hours (4 days)	Mon., Dec. 21	8 hours
20 lb	120 hours (5 days)	Sun., Dec. 20	10 hours
24 lb	144 hours (6 days)	Sat., Dec. 19	12 hours

The cold-water column uses Wyoming’s rule of 30 minutes per pound. The same page says to change the water every 30 minutes to keep it cold. The refrigerator must hold 40°F or below, the extension says.

How long to roast the turkey

University of Wyoming Extension gives 2¾ to 3 hours for an unstuffed 8 to 12 lb turkey at 325°F, and 3 to 3½ hours for a stuffed one. University of Illinois Extension agrees: its unstuffed page says to preheat the oven to 325°F and roast for 2¾ to 3 hours, and its stuffed page gives 3 to 3½ hours and says the stuffing must reach 165°F or higher.

Roasting times for heavier birds are not printed here. Check the chart on the turkey’s package or the University of Illinois Extension pages. A clock time for the oven depends on your dinner hour, so the printable leaves that line blank.

Safe temperatures for every Christmas main

University of Maine Cooperative Extension, in “In the Kitchen: Safe Minimum Internal Temperatures” (March 1, 2024), lists these minimums.

Dish	Minimum internal temperature	Rest time
Turkey, whole or ground, and stuffing	165°F (74°C)	none listed
Beef, pork, lamb steaks, chops and roasts	145°F (63°C)	3 minutes
Fresh (raw) ham	145°F (63°C)	3 minutes
Fully cooked ham, reheated	165°F (74°C)	none listed
Ground meats	160°F (71°C)	none listed
Egg dishes	160°F (71°C)	none listed
Casseroles with meat or poultry	165°F (74°C)	none listed
Leftovers	165°F (74°C)	none listed

The same page notes that cooked hams packaged in USDA-inspected plants reheat to 140°F (60°C). Rest-time notes in the table are only the ones the page lists. Times for prime rib or standing rib roast are not in the sources checked.

What to do with Christmas leftovers

University of Wyoming Extension says to put leftovers in the refrigerator or freezer within 2 hours. Refrigerated leftovers are safe for 3 to 4 days, the extension says, in a fridge at 40°F or below. Food cooked on Friday, Dec. 25 therefore stays within that window until Monday, Dec. 28 or Tuesday, Dec. 29 (computed). Reheat leftovers to 165°F, per University of Maine Cooperative Extension.
