How to use

Days between dates counts all working days from the start date up to (but not including) the end date β€” the standard inclusive/exclusive convention used by project tools. Add working days finds the calendar date that is exactly N working days from your start, skipping weekends and holidays.

Toggle the day circles to match your team's working week. For 4-day weeks uncheck Friday; for studios that work Saturdays, add it in. Preset holiday sets cover England & Wales bank holidays and US federal holidays for 2024–2028. Add your studio's custom shutdown dates in the box below β€” summer breaks, end-of-year closures, crunch free days, anything not covered by the presets.
