Frequently Asked Questions
How are days between dates calculated?
The calculator finds the absolute difference between two dates in milliseconds, then divides by 86,400,000 (milliseconds in a day). Weekdays are counted by iterating through each day and checking if it falls on a Monday–Friday.
What counts as a business day?
Business days (weekdays) exclude Saturdays and Sundays. This calculator does not exclude public holidays, which vary by country. For legal and contract purposes, always check whether holidays are excluded in your specific jurisdiction.
How many days until a specific date?
Set the start date to today and the end date to your target date. The calculator shows the exact number of days, weeks, and months remaining, along with a breakdown of weekdays and weekends.
