World Holiday & Business Day Planner

Country holiday calendars, business-day estimates, common business days across countries, and leave bridging around weekends and public holidays.

When you need a quick view of public holidays and shared working days across teams or trip planning.

Uses only the offline npm date-holidays package for calendars, business-day counts, common days across 2–5 countries, and leave bridging. Shows only library-returned types; never invents holidays or substitutes. Subdivisions only when the API supports them. PTO stays on-device.

Business-day estimate excluding weekends and public holidays. Not a legal determination of business closure.

公的祝日と週末を除く営業日目安です。法的な休業判定ではありません。
