Includes both start and end dates and counts Monday to Friday only. Public holidays, make-up workdays and personal schedules are not loaded automatically; enter excluded dates yourself.
Method and scope
Range mode includes both endpoints and counts eligible dates once. Add mode excludes the starting date; adding zero returns that date, and manually entered excluded dates can remove additional working days.
The manual calendar does not automatically know Taiwan public holidays or make-up working Saturdays. Duplicate exclusions only remove a date once.
The Taiwan administrative-agency calendar covers 2026-2027 only, with data version 2026-10-31 from New Taipei City personnel open data. It is not a universal employee roster, omits emergency closures and rejects dates outside its coverage; legal deadlines need separate confirmation.
