# holiday.agentic-jp.com

This host serves agents and applications that need accurate working-day counts within the Japanese calendar system. It is purpose-built for Japan-specific date arithmetic — useful for SLA calculations, payment deadline estimation, project scheduling, and compliance workflows that must account for Japanese national holidays. It does not cover other countries or provide real-time scheduling features.

## When to use this host

Use this host when an agent needs to count working days, weekends, or public holidays within a date range specifically under the Japanese calendar. It is the right choice for Japan-specific SLA calculations, payment deadline estimation, or project scheduling that must respect Japanese national holidays. Do not use it for business day calculations in any country other than Japan — use a country-appropriate calendar API instead. It is also not suitable for real-time or intraday scheduling, recurring event generation, or calendar management; those require a full calendar service.
