Direct answer
Count the scheduled hours actually missed, then subtract any holiday-covered hours the policy gives for the 9/80 pattern.
Compressed schedules need the schedule pattern, not just the weekday name.
Tie the answer to the record you are using: a time clock export, pay stub, PTO system, company calendar, or policy note. That is where most wrong results start.
Open PTO CalculatorFormula and worked example
Formula: PTO used = missed scheduled hours - holiday-covered hours.
Example: Example: a 9/80 schedule can make a Friday holiday cover fewer hours than a normal 8-hour Friday.
Keep the example visible while you replace the numbers. It is easier to catch a wrong lunch rule, date rule, or deduction period when the clean example is still on the page.

Step-by-step method
Key checks
- Write down the PTO balance, requested dates, daily hours, accrual timing, holidays, final deductions, notice dates, and schedule type before calculating.
- Calculate the ordinary version first. Add the exception only after the baseline is clear.
- Apply the rule: PTO used = missed scheduled hours - holiday-covered hours.
- Adjust for negative PTO, partial days, holidays, blackout dates, projected accrual, payout rules, final deductions, notice wording, and compressed schedules only when those details apply.
- Compare the result with your PTO system, HR portal, handbook, company calendar, manager note, pay stub, or employment agreement before using it for a real PTO request, resignation plan, final-pay estimate, deadline note, or workplace planning decision.
What can change the answer
The answer can change when negative PTO, partial days, holidays, blackout dates, projected accrual, payout rules, final deductions, notice wording, and compressed schedules are part of the real situation.
The calculator is still useful; the important step is matching the inputs to the record, schedule, paycheck, or policy you are checking.
If the number will go into a payroll question, PTO request, resignation note, invoice, or deadline message, save the assumption that changed the result.
Use scheduled hours, not weekday names
On a 9/80 schedule, a Friday can be a 9-hour day, an 8-hour day, or a regular day off depending on the week. The weekday name alone is not enough.
Before using PTO, write down the scheduled hours for that exact date. Then apply the holiday credit only if the policy says the holiday covers that scheduled day.
Key checks
- Check the 9/80 week pattern first.
- Confirm whether the holiday lands on a working Friday or an off Friday.
- Convert the final PTO need into hours.
Common mistakes
Key checks
- Do not assume a 9/80 Friday works like a normal Friday.
- Do not count holiday hours twice.
- Do not use calendar days when the PTO bank is tracked in hours.
Use the related calculator
Use PTO Calculator when you want to test this question with real inputs instead of doing the math from memory.
Copy the result with the assumptions beside it: dates, hours, pay rate, break treatment, deduction period, or policy detail.
Run a second scenario when one input changes the result sharply. That is usually where the real decision sits.
