About the Date Calculator
The Freemium.Tools date calculator counts days, working days and weeks between two dates, adds or subtracts time from a date, and works out an exact age — instantly and privately.
Notice periods, project deadlines, invoice terms and visa windows all hinge on an exact day count, and month lengths and leap years make mental arithmetic unreliable.
Three modes cover the common questions: how long between two dates, what date falls a set number of days or working days from now, and how old someone is to the day, including when their next birthday falls.
How to use it
- 1Pick a mode. Days between two dates, add or subtract time, or calculate an age.
- 2Enter the dates. Use the date pickers; today is filled in for you.
- 3Tap a result to copy. Totals are shown in days, weeks, working days, hours and minutes.
Frequently asked questions
How do I count working days between two dates?
Use Days between and read the Working days row, which counts Monday to Friday and skips weekends. Public holidays vary by country and are not deducted.
Does it handle leap years?
Yes. Calculations use real calendar dates, so 29 February and varying month lengths are handled correctly.
How is age calculated?
In completed years, months and days up to today, the same way official forms expect, plus the total days lived and the countdown to the next birthday.
What is a 30 working day deadline from today?
Choose Add or subtract, set the unit to Working days and enter 30; the tool skips weekends and gives you the exact date and weekday.
