Frequently asked questions
How do I count days between two dates?
Enter both dates and the tool returns the total days, plus the equivalent in weeks and remaining days. It handles month lengths and leap years automatically.
Does it include both the start and end dates?
It counts the number of days from the start date to the end date. For inclusive counts (counting both days), add one.
Can the dates be in any order?
Yes, the tool returns the absolute difference, so it doesn't matter which date is earlier.
