About this tool
The calculator reports the gap in years, months and days and the total in days and weeks. It uses calendar dates, so month lengths and leap years are handled.
Use it for contract periods, notice periods, warranty deadlines, trip countdowns or the date that falls 90 days after an event.
FAQ
Are both end dates counted?
The result counts the days between the dates; add one day if you want to include both the first and the last day.
Can I find the date after a number of days?
Yes, use the second calculator and enter a positive number to go forward or a negative one to go back.
