About this tool
The Turkey Thaw & Roast Time Calculator plans the two slowest parts of Thanksgiving dinner: safely defrosting a frozen bird and roasting it to a safe internal temperature. Enter the turkey weight in pounds or kilograms and whether it is stuffed, and the tool returns refrigerator thaw days, a faster cold-water thaw estimate, the oven roast time, a rest window, and — if you enter a serving time — the hour to slide it into the oven.
The math follows USDA-aligned rules of thumb. Refrigerator thawing at 40°F needs about one day per 4 pounds, so a 16 lb bird wants roughly 4 days; cold-water thawing (changing the water every 30 minutes) runs about 30 minutes per pound. Roasting in a 325°F oven to a 165°F internal temperature takes about 13 minutes per pound for an unstuffed bird and about 15 minutes per pound when stuffed, matching the midpoints of the standard USDA roasting table. A 20–30 minute rest lets juices redistribute before carving.
Everything runs locally in your browser and the numbers are estimates — ovens, starting temperature, and bird shape all vary. Always confirm doneness with a meat thermometer in the thickest part of the thigh (and the center of the stuffing) reading 165°F before serving. The start-time output subtracts the roast time plus a 25-minute rest from your target hour; if it lands the night before, a note flags it.
