Working Days Calculator
Count working days between dates with 2026 and 2027 public holidays. Check calendar coverage, plan deadlines and see country working-hour guides.
Choose the dates
Choose dates in 2026 or 2027 and a country. Both dates are included. Cross-year ranges use both holiday calendars; check the coverage note for incomplete previews.
Business days in the range
Calendar working days are Monday-to-Friday days minus the included holidays on those days. Saturday and Sunday are excluded. This is not a statutory working-time calculation.
This is the OPM federal employee holiday calendar, using observed weekdays for a Monday-to-Friday schedule. It is not a private-sector holiday entitlement. The 2027 calendar also includes 31 December, when New Year’s Day 2028 is observed by these federal employees.

How working days are counted
Count both selected dates, remove Saturdays and Sundays, then subtract the country’s included 2026 and 2027 weekday holidays. Missing dates in partial calendars are not estimated. Personal leave and company closures are separate adjustments.
Use it to plan deadlines, leave, and delivery dates. Sandtime.io then records the hours actually worked on those days, so plans and reality line up.
Working day questions
Are the start and end dates counted?
Both. The range is inclusive, so Monday to Friday counts as five days rather than four. Pick the same date twice to check a single day.
Does a public holiday on a weekend reduce the count?
No. A holiday landing on a Saturday or Sunday changes nothing, because that day was already outside the working week. Only holidays that fall on a weekday reduce the total.
Which days count as the weekend?
Saturday and Sunday. If your team works a different week, read the weekday figure and adjust that instead of the working-day total.
Where do the public holidays come from?
Choosing a country subtracts its included 2026 and 2027 holidays inside the range. Both years are used for cross-year ranges. Check the calendar coverage: partial previews omit unconfirmed dates, and company days off or regional holidays may need separate adjustments.
Can I use this to plan billable capacity?
As a ceiling, yes: working days times the hours in your standard day. What a project actually consumes is a different number, and only a time record shows it.
