How it worksShow guide
Introduction
Count inclusive working days between two dates, or add and subtract N working days from a start date. Weekend patterns cover Saturday–Sunday, Friday–Saturday, Sunday-only, or none. Optional holidays are one YYYY-MM-DD per line. Calendar add (months/days) is shown beside working-day add so month-end clamping is visible.
Step-by-step
- Choose count between dates, or add/subtract working days
- Pick a weekend pattern and optional holidays
- Read working, weekend, holiday, and calendar totals — or the landing date
Worked example
Monday 1 January 2024 through Friday 5 January is five working days (no weekend in range). Adding one working day to Friday 5 January lands on Monday 8 January.
Use cases
- Estimate contractor or leave days
- Find the date N business days from today
- Skip public holidays you paste in
- Compare weekend conventions used in different countries
Frequently asked questions
Is the range inclusive?
Yes. Both the start and end dates count when they are working days. Monday–Friday in the same week is five working days.
How do holidays work?
Each YYYY-MM-DD line is skipped as a working day. A holiday that falls on a weekend is counted as a holiday, not a weekend, in the breakdown.
What happens at month end?
Calendar add clamps: 31 January plus one month becomes 28 or 29 February. Working-day add steps day by day and skips weekends and holidays instead.
Which calendar is used?
Your device’s local calendar. The tool does not fetch a public-holiday API — paste the dates you care about.
