Days Calculator
This free date calculator calculates the difference between two dates. It can also add or subtract from a date. Both calculators work with business days and calendar days.
The day calculator finds the difference between two dates or the date that comes after a given number of days.
Choose Days between two dates, enter the start and end dates and press Calculate. The calculator shows the difference in days, working and weekend days, weeks, and in years, months and days. Check "include end date" if the last day should be counted too. The end date can be earlier than the start date; then the result is negative.
To find the date after a given time, choose Add days to a date or Add working days to a date, enter the start date and the number of days. To go back in time, enter a number with a minus sign "-". In working-days mode, Saturdays and Sundays are skipped.
Every calculation is saved, and you can share it with a link.
