About this tool
A date difference calculator counts the time between two calendar dates: total days, weeks and days, calendar months and days, and business days (Monday–Friday, excluding weekends). Useful for contract timelines, notice periods, project planning, visa durations and event countdowns.
FAQ
Are both days counted or just the gap?
The gap (end minus start). Add 1 manually if you need both dates included.
What are business days?
Monday through Friday — public holidays are not excluded (they vary by country).
Can I count down to a future date?
Yes — put a future date as the end date; negative results mean reversed order.
