Market Holiday

Know when global markets trade.

Global exchange calendars, trading schedules, market holidays, and market status information in one accessible platform.

Calendar intelligence

Global market calendar
intelligence.

  • Exchange trading hours and country directories
  • Calendar-based market status and the next scheduled opening
  • Market holidays and shortened sessions
  • Published data sources and methodology

Market status is calculated from calendar rules, not an official exchange feed. Confirm time-sensitive decisions with the venue.

Dataset provenance

Current reference records include dated TradingHours calendar snapshots. Source evidence is retained in the underlying records where available.

Venue authority

Official exchange websites are linked separately for verification of venue schedules and exceptional-session notices.

Update context

Dataset dates describe the schedule records. Current market status is recalculated from those records and local time; recalculation does not refresh the source data.

Structured calendar methodology and recorded source context. Licensed API access is a development objective.

Research & Development

Event intelligence.
Human judgement.

Research focus: AI-assisted notice analysis, analyst review and weather-related disruption assessment for financial market operations.

AI-assisted analysis

Extract dates, identify affected venues and flag potential schedule conflicts.

Analyst review

Check the source, assess the event and approve any calendar correction.

Venue-confirmed eventReviewed calendar update / operational alert

Concept only · AI analysis, review workflows and weather alerts are not enabled.

AI-assisted analysis & human oversight

Design objective: extract structured events from permitted source material, preserve source references and route uncertain changes for analyst review. Human approval would govern publication; model output alone would not amend a market calendar.

Severe-weather risk & venue confirmation

Design objective: correlate regional weather advisories with market locations and identify potential operational disruption. A weather warning is a risk signal, not a confirmed exchange closure. Calendar changes would require an authoritative venue notice.

How does the free exchange limit work?

Choose up to 10 distinct exchanges using the free-place control on an exchange page. Returning to an exchange, including its holiday and trading-hours pages, does not use another place. Directories remain accessible; cross-market calendar views are reserved for paid access.

Can a subscription be purchased now?

Purchasing is not enabled. Selecting a paid plan opens the account interface with the plan details; it does not create a subscription, collect a payment or enable API access.
