Date Difference Calculator
Count the days, weeks, months and years between two dates, optionally excluding weekends.
Find the exact time between two dates as days, weeks, months and years. Optionally count working days only, excluding Saturdays and Sundays.
How it works
Choose a start and an end date. The tool reports the total number of days, the same span broken into years, months and days, and the number of weekdays. Tick Include end date to count both the first and the last day.
Examples
- 1 January 2026 to 31 December 2026 is 364 days (365 including the end date).
- Weekdays between two dates exclude Saturdays and Sundays but do not account for public holidays.
Frequently asked questions
Does the tool count public holidays?
No. Working-day counts exclude weekends only, because public holidays differ by country and region.
What does include end date mean?
It adds one day so that both the start date and the end date are counted.
Can the end date be before the start date?
Yes. The result is shown as a positive span between the two dates.
