How this service works
Cross-border business day overlap between Japan and any country (ISO2): checks holidays in both countries plus weekends for a given date. Use for international meeting scheduling, FX settlement dates (T+2), global team coordination, contract deadlines, logistics cutoffs.
Output
Returns whether the queried date is a mutual business day in Japan and the specified country, with flags indicating whether either country has a public holiday or weekend on that date, enabling reliable cross-border scheduling and settlement date validation.
Example use cases
Example prompt
“Is March 20, 2025 a business day in both Japan and the US? I need to confirm it works as a settlement date for a JPY/USD FX trade.”
Technical details
Endpoint
GEThttps://jp-data-api-production.up.railway.app/calendar/overlapWhen to prefer
Use this endpoint when you specifically need to verify business day overlap between Japan and another country — for FX settlement (T+2 calculations), international contract deadlines, cross-border logistics cutoffs, or scheduling meetings across Tokyo and a foreign office. It is more precise than a generic holiday API because it simultaneously evaluates both Japan's holiday calendar and the counterpart country's calendar in a single call.
Side effects
- Invalid or missing date format (not YYYY-MM-DD) — likely 400 error
- Invalid or unsupported ISO2 country code — likely 400 or empty result
- Future dates beyond holiday data coverage — may return incomplete results
- Network timeout or Railway platform downtime — 5xx error
- Missing required query parameters (country or date) — 400 error
