Direct answer
Calculate holiday pay across midnight by splitting the shift into the hours before and after midnight, then applying the holiday premium only to the hours that qualify under the policy.
Best fit search phrase: "calculate holiday pay shift crosses midnight". Use the calculator after you have the source record, policy wording, or pay-stub line in front of you.

A night shift from 10 PM to 6 AM can touch two calendar dates. The holiday portion might be the first two hours, the last six hours, or the whole shift depending on the policy wording.
Shift: 10 PM Dec 24 to 6 AM Dec 25. If only Dec 25 hours qualify, holiday hours = 6. At $20/hour and 1.5x, holiday gross = 6 x $30 = $180.
Working rule
Holiday gross = qualifying holiday hours x holiday rate, after splitting the shift by the policy's holiday window.

Checklist before you rely on the number
Key checks
- Find the holiday window in the policy.
- Split the shift at midnight or the stated holiday start time.
- Count only qualifying holiday hours.
- Apply the correct premium rate.
- Check whether night differential or overtime is separate.
Practical notes
Some policies treat the whole shift as holiday if it starts on the holiday; others use exact clock hours.
If the shift also has night differential, keep that premium separate before checking totals.
If the shift crosses a workweek boundary, overtime may need a separate weekly calculation.
Mistakes that change the result
Do not assume all overnight hours qualify as holiday hours.
Do not forget unpaid meal breaks in the qualifying window.
Do not stack holiday, overtime, and differential unless policy says they stack.
