Business days between two dates

Quick answer: business days between two dates

• Counts working days and excludes weekend days by your chosen pattern.
• Inclusion mode (include start/end) can change totals by up to two days.
• Holiday presets are illustrative; add custom closures when needed.

What the calculator does

The business day counter shows the total workdays, calendar days considered, weekends excluded, holidays excluded, and business days kept. It works like a date range calculator that shows what you keep and what you drop, so you can see why a count changed.

Inclusion modes explained

Inclusion mode decides whether the start date, end date, both, or neither are counted. Exclude both removes both edges. Include start keeps day one. Include end keeps the last date. Include both adds both edges. Switching this can move the total by two business days, so match it to your policy before you share numbers.

Weekends and custom weekend patterns

Standard weekend is Saturday–Sunday, but some teams use Friday–Saturday or Sunday–Thursday. Set the weekend to match your market so the calculator excludes the right days. This is vital for operations that need to exclude weekends and holidays correctly, such as logistics or shared service centres.

Holidays and custom exclusions

Holiday presets supply common public holidays for a given year, but they may not cover every region or company closure. Use them as a starting point, then add custom holidays to the list so your workdays between dates match reality. Review presets each year because dates move. Learn how to exclude holidays.

Breakdown and safe range limit

Breakdown shows which dates were kept, which were weekend days, and which were holidays. It is capped for performance on very long ranges, so you may see a safe range limit. Keep ranges modest when you need full detail or export results in segments.
