Never thaw a turkey on the counter or in hot water – bacteria multiply quickly above 40 °F (4 °C). If you run out of time, a turkey can be roasted from frozen; it just takes about 50% longer.

Results update as you type, and every field accepts the units shown in its menu.
How it works
Choose the method, the weight, and whether you know the start time or the time you need it ready.
Tips
- Buy the turkey early and allow enough fridge thawing time – about one day per 4–5 lb.
- Always check the thickest part of the thigh and breast with a thermometer: 165 °F (74 °C).
- Let the turkey rest 20–30 minutes before carving so the juices settle.
- Make a timeline working backwards from when you want to eat.
Common mistakes to avoid
- Thawing a turkey on the counter, which lets bacteria grow.
- Stuffing the bird the night before.
- Relying only on the pop-up timer instead of a thermometer.
Inputs explained
| Field | What to enter |
|---|---|
| Thawing method | Choose one: Refrigerator, Cold water, Microwave, On the counter (unsafe) … |
| Turkey weight | Units: lb, kg, oz, g |
| I know the | Choose one: Start time, Time it must be ready |
| Date | A date |
| Time | A clock time (hours and minutes) |
What each result means
- Date = floor([Moment (days)])
- Time = ([Moment (days)] – floor([Moment (days)]))×24
Formula
Refrigerator: 24 h per 4–5 lb (≈ 5.3 h per lb)
Cold water: 30 min per lb
Microwave: about 6 min per lb (check the manual; cook immediately)
Ready = start + thawing time; start = ready − thawing time
Worked example
Inputs — Thawing method: Refrigerator; Turkey weight: 14 lb; I know the: Start time; Date: 2026-10-25; Time: 18:00.
Results — Thawing time = 74 h 40 min; Date = Wed, October 28, 2026; Time = 20:40; Meaning = The turkey will be thawed by this date and time; Safety = Keep in the fridge at 40 °F (4 °C) or below; cook within 1–2 days.
