2. Enter the end date.

Frequently asked questions
How do I calculate the number of days between two dates?
Enter both dates and the calculator returns the number of days. Choose whether the end date is included.
Does it include the start and end date?
By default the end date is excluded. You can include it with the option provided.
How do I count only working days?
Use the business days result, which counts Monday to Friday.
Does the calculator handle leap years?
Yes. Leap years are handled automatically.
Can I calculate weeks between dates?
Yes. The result shows the span in days and weeks plus days.
Why is my answer off by one day?
Usually because of the end date setting. Counting both the first and last day gives one more than counting the gap between them.
Is the date I enter stored?
Dates are submitted for calculation and not stored as personal history.
