How this service works
Tells whether a date is a banking/settlement day for euro payments (TARGET2/SEPA), US Fedwire or Switzerland (SIX), with the reason and the next banking day.
Output
The endpoint returns a JSON object indicating whether the queried date is a banking/settlement day for the specified zone (TARGET2, US, or CH), the reason (e.g. holiday name) if it is not a banking day, and the date of the next valid banking day in that zone.
Example use cases
Pre-trade settlement date validation
“Before we send a cross-border euro wire today (June 19, 2025), can you confirm whether it's a TARGET2 banking day and, if not, tell me the next one so we know when it will actually settle?”
US Fedwire cut-off planning
“Is July 4, 2025 a valid banking day for US Fedwire transfers? We need to know if we should schedule the payment the day before.”
Swiss SIX settlement check
“Can you check if August 1, 2025 is a banking day in Switzerland under SIX, and what the reason is if it's not?”
Technical details
Endpoint
GEThttps://market-calendar-api.onrender.com/v1/is-banking-day?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether a specific date is a valid payment settlement day for a particular financial zone (TARGET2/SEPA, US Fedwire, or Swiss SIX) before scheduling or routing a payment, or when you need to determine the next valid banking day for cut-off and scheduling logic. It is purpose-built for payment operations teams, treasury systems, and financial agents that need authoritative holiday-aware settlement calendar lookups per zone — not for general business-day calculations or stock market trading day checks.
Side effects
- Missing required 'zone' parameter returns a 400 or validation error
- Invalid zone value (not TARGET2, US, or CH) returns an error
- Malformed date format (not YYYY-MM-DD) causes a parsing error
- Network/server unavailability on the Render.com host returns a 503
- No response for very far future dates if calendar data is not populated
