How to use Date & Age Calculator

Choose age, date difference, business days or date arithmetic and enter the required dates. Inspect the result with your intended start and end dates.

What to check before using the result

Business-day calculations may not account for regional public holidays. Inclusive and exclusive date counting can give different results.

Example: Counting a Monday-to-Friday interval

From Monday to Friday in the same week, the date difference is four days. Weekday counting excludes the starting date and includes the ending date; it skips Saturday and Sunday but does not subtract public holidays.
