- Finance teams and developers handling settlement dates
- Worth noticing
- The homepage lists 35 exchanges, 17 settlement currencies, and 1,597 country and regional calendars.
Field notes
The examples show the same request in curl, Python, JavaScript, and an Excel formula, and the page says spreadsheets can use the service without an add-in. Its calendar list distinguishes settlement systems such as Fedwire, TARGET2, and CHAPS from public-holiday calendars; it also describes early closes by time. These are homepage descriptions of the service's coverage and workflow, not independent checks of the underlying data.
