> The turkey defrost calculator works out how long a frozen turkey takes to thaw safely – in the refrigerator (about 24 hours per 4–5 lb) or in cold water (about 30 minutes per lb) – and the day to start thawing for your dinner.

## Inputs

- Thawing method
- Turkey weight (lb, kg, oz, g)
- Dinner date

## Results

- Thawing time
- In days
- Start thawing on
- Note

## Formula

```
Refrigerator: hours = weight (lb) × 24 ÷ 4.5
Cold water: hours = weight (lb) × 0.5 (change the water every 30 minutes)
Start date = dinner date − thawing time
```

## Explanation

The USDA recommends thawing in the refrigerator, in cold water or in the microwave – never on the counter, where the outside can sit in the "danger zone" (40–140 °F) while the inside is still frozen. A fridge-thawed turkey can then be kept 1–2 days before cooking.

### How to use the Turkey Defrost Time Calculator

- **Thawing method**
- **Turkey weight**
- **Dinner date**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Choose the thawing method, enter the turkey's weight and the date of your dinner.

### 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.

## Worked example

Inputs — Thawing method: Refrigerator (40 °F / 4 °C or below); Turkey weight: 14 lb; Dinner date: 2026-11-26.

Results — **Thawing time = 74 h 40 min**; In days = 3.1; Start thawing on = Sat, November 21, 2026; Note = Leave an extra day of margin; a thawed turkey keeps 1–2 days in the fridge.

## FAQ
