Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
No public holidays are built into this calculator. Only the dates you list here are treated as holidays.
Both the start and end dates are counted when they are business days. None of your listed holidays fell on a weekday in this span.
- 1Choose whether to count business days between two dates or to add business days to a date.
- 2Pick the dates (and the number of days, for add mode).
- 3Choose the weekend: Saturday and Sunday, or Friday and Saturday.
- 4Paste your holidays, one date per line in YYYY-MM-DD format.
- 5Read the business day count, or the resulting date, plus any of your holidays that fell on a weekday in the span.
The span holds 12 calendar days and 2 weekend days (Saturday 7 and Sunday 8 November). With Wednesday 11 November listed as a holiday, the business day count is 9, and the tool names 11 November as the holiday that fell on a weekday.
- Counting mode includes both the start and the end date when they are business days. Add mode does not count the starting date; each added day lands on the next business day.
- There is deliberately no built-in holiday list for any country. A built-in list would go stale and would silently use another country's calendar; your own list is always current for your situation.
- Holidays that fall on a weekend day change nothing and are not reported as hits; only holidays on a weekday reduce the count.
- Dates are read as plain calendar dates, with no times or timezones involved.
Built-in holiday sets go out of date and differ even within countries, so a wrong built-in list would quietly produce wrong deadlines. Listing your own holidays keeps the answer right for your workplace. The dates you list are the only ones treated as holidays.
About this tool
The Business Days Calculator counts working days between two dates, or adds a number of business days to a date, skipping your chosen weekend and the holidays you list yourself. It matters for delivery promises, payment terms and deadlines. No public holidays are built in, on purpose: holiday calendars differ by country and year, so the only holidays removed are the ones you type in.
