Frequently asked questions
Does the order of the two dates matter?+
No, enter them in either order; the calculator automatically works out which is earlier.
What counts as a "weekday" in the weekday total?+
Any day that isn't a Saturday or Sunday, counting both the start and end date if they fall within the range.
Is this the same as the Age Calculator?+
It uses the same precise year/month/day math, but works for any two dates, not just a birth date and today.
