3 days in the fridge. For a 5 PM Thanksgiving dinner on Thursday, November 26, 2026, move it to the fridge on Monday, November 23. In cold water: 6 hours.
Fridge thawing takes about 24 hours for every 4 to 5 pounds. That is the USDA rule. Keep the fridge at 40 F or below. Put the turkey on a tray, breast up. Leave it in its wrapper. Give it the full 3 days.
Once thawed, it keeps 1 to 2 days in the fridge before you cook it. An early start is safe. A late start is the problem.
Dinner is Thursday, November 26, 2026. Your band is "up to 12 lb." Every bird in that band shares this move date: Monday, November 23. All the dates by weight are on the Thanksgiving dates page.
These are the same dates the ThawDay calculator gives for a 5 PM Thanksgiving dinner. Dinner at a different hour? The move date stays the same. The calculator stamps your exact time.
Cold water takes 6 hours for 12 lb. Seal the bird in a leak-proof plastic bag. Submerge it in cold tap water. Change the water every 30 minutes. Cook it right after it thaws. Full steps: thawing a turkey in cold water.
USDA's third safe way is the microwave: follow your oven manual for size and timing, and cook the turkey right after it thaws. Never thaw a turkey on the counter. The outside warms up hours before the inside thaws. Bacteria grow in that warm layer.
Tell the calculator your weight and dinner time. Get your buy, thaw, brine, and roast dates. Or ask in your own words: "12 lb frozen turkey, dinner Thursday."
