Frequently asked
questions

How do I calculate how many days between two dates?

Use the "Date Difference" tab. Enter a start date and an end date, then click Calculate. The result shows the exact number of days, weeks, months, and years between the two dates.

Can I add or subtract business days?

Yes — in the "Add / Subtract Days" tab, check "Skip weekends" and the calculator will only count Monday–Friday when adding or subtracting days.

Does it account for leap years?

Yes. All date arithmetic is done using the browser's native Date object, which correctly handles leap years and varying month lengths.
