Calculate days between dates, add days, count business days, and more.
Use our Date Difference calculator. Enter your start and end dates, and optionally choose whether to include the end date in the count.
Business days are weekdays from Monday to Friday. Our business days calculator counts only these days, excluding weekends.
Use our Add/Subtract Days calculator. Enter your start date and the number of days to add (or subtract using negative numbers).
Currently, our business days calculators exclude weekends but do not automatically exclude public holidays, which vary by country and region.
