No, and this is the part most pages on the subject skip past. In the US there is no federal requirement for a private employer to pay extra for hours worked on a holiday, and no federal requirement to give paid holidays off in the first place. The Fair Labor Standards Act covers the minimum wage and overtime beyond 40 hours in a workweek. It says nothing about which days those hours fall on.
So holiday pay is a benefit, not an entitlement. It comes from your employer policy, your offer letter, or a union agreement, and the rate is whatever that document says it is. That is why the calculator above asks you what your employer pays rather than assuming a multiplier: the honest answer to what a holiday shift is worth depends on a policy, and only you can read yours.
