Date Calculator
A date calculator helps you quickly measure the time between two calendar dates. This is useful for planning trips, counting down to deadlines, checking contract lengths, and working out how many days have passed since an important event.
Instead of manually counting days on a calendar, you can enter a start date and an end date and let the calculator do the work instantly. The result is shown in both days and weeks for quick reference.
Formula
The calculator uses a simple date-difference formula:
totalDays = absolute value of (endDate - startDate) totalWeeks = totalDays / 7
Where:
- startDate is the first date
- endDate is the second date
- totalDays is the absolute number of days between the two dates
- totalWeeks is the equivalent time in weeks
How to use
- Enter the start date.
- Enter the end date.
- Click calculate.
- View the difference in days and weeks.
