Count or add working days with your own weekend pattern and optional holiday dates.
Enter values or load the example.
All inputs stay in this page. No uploads or application history. Input edits invalidate generated outputs. Numeric quick sliders never clamp wider exact fields. Gregorian years 0001–9999. Supply your own weekends and optional holiday dates (up to 5,000 entries). No national or legal holiday rules are inferred. Count mode uses explicit endpoint inclusion and signs reversed ranges. Offset mode excludes the starting date; zero returns the original date. Weekend holidays are never subtracted twice. Calculation worker deadline: 10 seconds.

Your dates, clock settings and calendar labels stay on your device. Self-hosted browser code processes the inputs without uploads, accounts or application history. Browser time-zone rules and your device clock are used without remote lookup.

No. Timers/clocks run only in the active browser page or workspace panel. Closing, Reset or switching tools releases that session. Background throttling and device sleep can delay feedback, and device-clock adjustments affect wall-clock timers. No notification permission, service worker or server alarm is used.
No. Weekend/holiday rules are supplied by you; no regional legal calendar is inferred. Time-zone calculations use the browser’s installed rules. The Meeting planner rejects skipped local times and requires an explicit occurrence for repeated times.
No application input history is stored. Reports/downloads and explicit clipboard copies exist outside the tool when you request them. Clear, Reset, workflow switching and page exit release current application data; this is not a physical memory-erasure guarantee.
