About the Date Difference
Measure the gap between two dates in every useful form at once: calendar difference in years, months and days, exact total days, whole weeks plus remainder, and business days versus weekend days counted inclusively. The order of the two dates does not matter โ the tool always takes the earlier as the start.
How to use the Date Difference
- Pick the start and end dates in the two date fields.
- Read the Difference tile in years, months and days.
- Check Total days and the weeks-plus-days breakdown.
- Use the Business days figure (Monday to Friday, both dates inclusive) for project planning.
Date Difference FAQ
How are business days counted?
Every Monday to Friday between the dates, including both endpoints, counts as a business day; Saturdays and Sundays are reported separately as weekend days.
Does it account for public holidays?
No. Holidays vary by country and region, so the count is purely weekdays โ subtract your local holidays manually if you need a precise working-day figure.
What if I enter the dates backwards?
Nothing breaks: the tool swaps them internally and always reports a positive duration from the earlier to the later date.
