Date
Workday Calculator
Workday calculation rules
The workday calculator counts dates between a start date and end date while applying selected exclusion rules.
You can exclude Saturdays, Sundays, and Korean public holidays to approximate real working availability.
How to read the result
The main result is the number of included workdays. Breakdown rows explain which dates were excluded by each rule.
Use the rate and average values as planning aids, not payroll or legal conclusions.
Examples
Project availability
Count working days in a project window after weekends and holidays are removed.
Leave or schedule checks
Compare calendar days with actual workdays before sharing a schedule.
Limits
- Korean holiday data is bundled and may not cover every future policy change.
- Company-specific work calendars are not included.
- The result is a planning estimate, not legal advice.
