Methodology reference

The rules below describe how schedule data is interpreted throughout the product.

Scope of coverage

We track exchange-level trading hours, full market holidays, shortened sessions, and local exchange time zones. Each exchange record combines a dated trading-hours snapshot with a dated holiday-calendar snapshot, then organizes coverage by market, country, and region.

Official source authority

Each market page links to the official exchange website when a venue-owned source can be independently identified. Official holiday calendars, emergency notices, clearing communications, and broker alerts take priority over normalized records on this site.

Data freshness

The newest exchange snapshot in the active dataset is dated Aug 4, 2026. Snapshot dates describe the underlying schedule files; live open or closed status is recalculated from the exchange's local clock, weekly sessions, and same-day exceptions.

Market status logic

Live status combines each exchange’s local time, regular weekday sessions, and same-day holiday overrides. A venue may be open, closed, on holiday, or on a half day depending on its current local session window.

Treatment of half days

Half days remain separate from full closures. When shortened opening or closing times are available, their local session boundaries are preserved so reduced trading windows are not mistaken for full holidays.

Timezone presentation

Schedules are displayed in the exchange’s local timezone and retain the IANA identifier. Viewer-time conversion is supplementary and never changes the source schedule’s local meaning.

Operational boundary

Market Holiday is an informational reference. Official exchange notices, clearing communications, and broker alerts take priority for time-sensitive operational decisions.
