Thawing on the counter is the method to avoid: the outside sits at room temperature for hours before the middle has thawed at all. The refrigerator is slow but no part of the bird ever leaves safe temperature, and it will keep a further day or two once thawed.

The formula

refrigerator: 24 hours per 4.5 lb ; cold water: 30 minutes per lb

Two safe methods, and one that is not

In the refrigerator a bird thaws at about 24 hours per 4.5 lb, which for a large turkey means starting three or four days ahead. Cold water is far faster at 30 minutes per pound, but the water must be changed every half hour or it warms into the range bacteria like. Thawing on the counter is the one to avoid entirely: the outside sits at room temperature for hours before the middle has thawed at all.

Why the fridge is worth the wait

A refrigerator thaws slowly enough that no part of the bird leaves safe temperature, and a thawed bird will keep a further day or two in there before cooking. That slack is worth a great deal when the schedule is tight, and it is the reason the slow method is the recommended one despite the planning it demands.

Partly frozen is not a disaster

A bird still icy in the cavity on the morning can be finished in cold water, or simply cooked with about 50 % added to the time. What it must not be is cooked to the clock and served on trust — a partly frozen bird is exactly the case where the thermometer is not optional.

Recipes are starting points

Ovens run hot or cold by 20 degrees, flour absorbs water differently by season and brand, and the same joint of meat cooks at a different rate depending on its shape rather than its weight. Everything here is a planning figure that gets you close enough to start, and the thermometer, the scales and your own notes from last time are what finish the job.
