Days Between Two Dates

Loading holiday countries...

Public holiday data is loaded from the server via date-holidays and may vary by country, state, or region. This version uses country-level data only. When holiday data is unavailable, the calculator safely falls back to weekend and weekday rules only.

Days Between Two Dates Calculator

The Days Between Two Dates calculator calculates the number of days between a start date and an end date. It can be used for simple calendar calculations or more specific date ranges that exclude weekends, public holidays, or selected weekdays.

You can choose whether to include the end date in the calculation and customize which days should be counted. When public holiday exclusions are enabled, the calculator can also display holidays that were removed from the result.

Business Days Between Two Dates

Calculate working days by excluding weekends from the selected date range. You can also remove available public holidays when you need a more specific business-day count.

Working Days Calculator

Use weekend, holiday, and weekday exclusions to calculate working days for schedules, projects, deadlines, and other periods where not every calendar day should be counted.

Days Between Dates Including End Date

Enable the end date option when the final day of the selected period should be included in the calculation. This is useful when your counting method treats the final date as part of the interval.

Days Between Dates Excluding Weekends

Remove weekend days from a date range when you want to count weekdays rather than every calendar day. Additional weekday controls can be used for schedules with different non-working days.

Days Between Dates Excluding Holidays

Select a supported country and use public holiday exclusions when holidays should not count toward the result. Matching excluded holidays can be shown with their names and dates.

Calendar Days Calculator

Keep exclusion rules disabled when you simply need the calendar-day difference between two dates without removing weekends, holidays, or specific weekdays.

Custom Weekday Calculator

Select individual weekdays to exclude from the calculation. This can be useful for work schedules, recurring closures, school schedules, or other calendars that do not use a standard five-day workweek.
