Frequently asked questions
Is anything uploaded?
No. All date calculations run in your browser with nothing uploaded, and it works offline.
How is the difference shown?
As full years, months and days between the two dates, plus the totals in days and weeks and the number of weekdays.
What counts as a weekday?
Monday to Friday. The weekday total excludes Saturdays and Sundays, which is useful for working-day estimates.
Can I add or subtract days from a date?
Yes. Use the second section to add or subtract any number of days from a date and see the resulting date and weekday.
Does it handle leap years?
Yes. It uses real calendar dates, so leap years and month lengths are handled correctly.
