What This Skill Does
Connects AI agents to Korean public holiday data and business day calculations via the HuDy MCP server. Supports querying holidays, counting business days between dates, adding or subtracting business days, and managing custom company holidays.
Uses official Korean government holiday data (data.go.kr) and handles custom holidays automatically in all calculations, removing the need to maintain a separate holiday calendar.
When to use it
- Counting business days remaining in a contract deadline
- Checking if a specific Korean date is a workday
- Scheduling a payment 10 business days after invoice date
- Registering a company founding anniversary as a custom holiday
- Querying all public holidays in a given quarter
