Direct answer
Count weekdays across the date range, then remove year-end holidays and any company closure dates.
Year-end counts are easy to overstate when closures are not entered.
Use this answer for counting business days when the range crosses December and January holidays. Compare the inputs with your PTO system, HR portal, company calendar, handbook, manager note, or employment agreement before relying on the result.
Open Work Days CalculatorFormula and worked example
Formula: Business days across year end = weekdays in range - excluded holidays and closures.
Example: Example: a 12 business days range from late December to early January may lose Christmas, New Year's Day, and 2 company closure dates.
Keep the formula and example beside the calculator result so you can spot whether the difference came from hours, dates, pay frequency, or policy wording.

Step-by-step method
Key checks
- Write down the PTO balance, daily hours, date range, accrual timing, holidays, notice period, and policy wording before calculating.
- Calculate the clean version first so the baseline is visible.
- Apply the rule: Business days across year end = weekdays in range - excluded holidays and closures.
- Adjust for partial days, holidays, blackout dates, projected accrual, payout rules, notice wording, and custom schedules only when those details apply.
- Compare the result with your PTO system, HR portal, company calendar, handbook, manager note, 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 partial days, holidays, blackout dates, projected accrual, payout rules, notice wording, and custom schedules are part of the real situation.
That does not make the calculator unreliable. It means the inputs need to match the real rule, schedule, paycheck, or policy record.
If the result affects pay, PTO, notice timing, or a formal deadline, treat it as a planning estimate until the official source confirms it.
Real-world check
Year-end counts need the company closure calendar, not just federal holidays. Many offices close extra days around Christmas or New Year, and those days can move the answer.
If the deadline matters, save the skipped dates with the result. That gives you something concrete to send when someone asks why the date moved.
Common mistakes
Key checks
- Do not count holidays as business days if the rule excludes them.
- Do not forget company closure days around the holiday period.
- Do not restart the count incorrectly when the year changes.
