# Working Days Calculator Count the business days between two dates — excluding weekends and any holidays you list. Runs entirely in your browser. ### How it works The tool steps day by day from the start to the end date (in UTC, so daylight saving never miscounts). Saturdays and Sundays are counted as weekend days; every other day is a working day — unless its date appears in your holiday list *and* it falls on a weekday, in which case it’s subtracted too. Toggle whether the end date itself is included. Everything runs locally. --- *Source: [ocxly.com/working-days-calculator.html](https://ocxly.com/working-days-calculator.html) — OCXLY, free 100% client-side privacy-first tools.
