Date Difference Calculator

- Set the end date.
- Read the total in days, weeks and months, plus the working-day figure that excludes Saturdays and Sundays.
About the Date Difference Calculator
Manual date counting goes wrong on month boundaries and leap years, which matters when you are calculating notice periods, project deadlines, visa stays or interest days. This calculator uses real calendar arithmetic and gives you both the raw day count and the business-day count, so you can quote whichever one your contract or form asks for.
Frequently asked questions
How many days are between two dates?
Enter both dates above. The tool counts every calendar day including leap days, and shows the same span expressed in weeks and months.
Does it count working days only?
It shows both. The business-day figure excludes Saturdays and Sundays; it does not know your local public holidays, so subtract those yourself.
Is the end date included?
The count is the span between the two dates. If your form counts the final day as well, add one to the total.
