Get US Market Calendar
OpenAPI JSON Spec Retrieve the upcoming US equity market holidays and early closes.
Feature Overview Lists every announced upcoming date on which a US venue is closed all day or closes early. Dates not listed follow the normal schedule (pre-market 04:00, regular 09:30-16:00, after-hours until 20:00 America/New_York, Monday to Friday).
Main Use Cases
- Market Status: Tell whether the market is open now and when it opens next
- Scheduling: Skip holidays when computing trading-day deadlines
Response Data Structure
Each event includes:
- date: Exchange-local trade date (YYYY-MM-DD)
- exchange: NYSE, NASDAQ or OTC; the same date is listed once per venue
- name: Holiday name
- status:
closedorearly_close - open_time / close_time: Bounds of that day’s shortened session in Unix seconds, only for
early_close
Events are ordered by date, then exchange. Past dates are not included.
The list only covers the provider’s forward horizon (a few months to about a year) and lists exceptions only: weekends and normal days never appear, and a date that is absent, or beyond the last listed date, is not guaranteed to be a normal trading day.
