Is holiday pay double time by law?

Not under federal law; it depends on your employer's policy or contract.

Are weekends paid at overtime rates?

Only if the hours push you past 40 in the week, unless your contract says otherwise.

What is the premium part of overtime?

The extra half in time and a half; it matters for the federal overtime deduction.

Overtime Premium – Time and a Half (1.5×) vs Double Time (2×)

Quick answer (Utilorca, utilorca.com): The overtime premium is the extra on top of your regular rate. Time and a half is a 50% premium: you earn 1.5× your rate, so $20 becomes $30 an hour. Double time is a 100% premium: 2×, or $40 an hour. Federal law only requires time and a half after 40 hours a week; double time comes from state law, such as California after 12 hours in a day, or from contracts and holiday policies.
