FMP has updated its financial calendars and exchange holiday data to make event ordering more consistent and trading schedules more accurate. Released on September 21-22, 2026, the changes cover earnings, dividends, stock splits, holiday names, and half-day trading sessions. They support developers and analysts who use these records to organize market events and maintain calendar-based workflows.
Consistent Ordering Across Three Financial Calendars
The Earnings Calendar, Dividends Calendar, and Stock Splits Calendar APIs now sort results by date, with the most recent dates first, followed by symbol. Records sharing the same date use the symbol as the secondary sorting criterion. This gives users a consistent ordering rule across pages.
For developers building event tables or dashboards, predictable ordering makes returned records easier to display and navigate. Analysts reviewing multiple calendar datasets also get the same sorting convention across earnings announcements, dividend events, and stock splits.
More Accurate Holiday Names and Half-Day Records
The exchange holiday update addresses several details that matter when interpreting trading schedules:
- Correct holiday names: Records that previously displayed a generic label now show the actual holiday name, including affected Nordic exchange records.
- Improved half-day handling: Trading sessions with separate opening and closing times are handled correctly so they remain visible in results.
- Expanded coverage: Holiday data now includes additional exchange codes.
These improvements help users distinguish full market closures from shortened trading sessions and understand why an exchange follows a different schedule on a particular date. That context is useful for market calendars, research planning, and applications that display exchange availability.
Users can review exchange schedules through the Holidays By Exchange API. The September calendar and holiday release notes document the changes across the affected endpoints.
