Date Range Calculator — Days Between Two Dates
Calculate Days Between Two Dates
Compare a start and end date to see elapsed days, working days, weeks, hours, seconds, and a calendar breakdown. Inclusive counting can add the final day, while weekend exclusion skips Saturdays and Sundays.
Key Features
- Elapsed-day and optional inclusive-day counting
- Weekend exclusion for a Saturday-and-Sunday working-day total
- Totals in days, working days, weeks, hours, and seconds
- Calendar breakdown in years, months, and days
How to Use This Tool
- Choose the start date and end date for the range.
- Turn on Inclusive Mode if the final date should count as a full day.
- Turn on Exclude Weekends when Saturdays and Sundays should not count as working days.
- Review the total and calendar-breakdown cards.
Important to Know
- Weekend exclusion does not remove public or custom holidays.
- A start date after the end date produces negative totals rather than automatically swapping the dates.
- Inclusive Mode changes the total-day count by adding the final calendar day.
