Common Use Cases

How Are Weekdays Calculated?

When you select "weekdays only," the calculator counts Monday through Friday, excluding Saturday and Sunday. It does not account for public holidays, which vary by country and region.

FAQ

Does this account for leap years?
Yes. The calculator uses JavaScript's native Date object which correctly handles leap years. February 29 is included when applicable.
Does the weekdays count include holidays?
No. The weekday calculation counts Monday-Friday but does not exclude public holidays. For exact business days, you'd need a holiday calendar.
How accurate is the months calculation?
Months have varying lengths (28-31 days), so we use the average month length of 30.44 days for approximation. For exact results, use the days count.
Can I calculate days until a future event?
Yes. Enter today's date as the start date and your event date as the end date to see the countdown.
