About Business Days Excluding Holidays Calculator

Business days are weekdays minus public holidays that fall on a weekday - holidays landing on a weekend cost nothing. From 5 January to 31 December 2026 there are 258 weekdays, so eight weekday holidays leave 250 business days, or 50 working weeks. That figure is the denominator for annual capacity planning.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why count only weekday holidays?

Because a holiday on a Saturday does not remove a working day. Some jurisdictions grant a substitute weekday, which should then be counted.

How many business days are in a year?

Typically 250-253 depending on how weekends and holidays fall - 260 weekdays minus eight to ten holidays.
