Can I count backwards?

Yes — enter a negative number of workdays to find the date N working days before the start, useful for “submit 10 working days prior” rules.

How is this different from the sprint calculator?

Same engine, different framing: this one is built around a custom holiday list and single deadlines rather than sprint lengths.

“Within 5 working days” only means something once you know which days don't count. Give this a start date, a number of workdays, and the holidays your office observes; it returns the real calendar date, having skipped every weekend and listed holiday in between.

How to use it

1.Pick the start date and the number of workdays.
2.List holidays to exclude, one date per line.
3.Read the resulting calendar date and weekday.
