How Exchange Calendar Works

Scope of coverage

We track exchange-level trading hours, full market holidays, shortened sessions, and local exchange time zones. Coverage is organized by market, country, and region so you can move from a single exchange view into broader comparisons without changing terminology or time-zone conventions.

Market status logic

We determine live status from each exchange’s local time, its regular weekday session structure, and any same-day holiday override. A market may appear as open, closed, holiday, or half day depending on whether the current local time falls inside a scheduled session and whether that trading date carries a full-close or shortened-session rule.

Treatment of half days

We track half days separately from full market closures. Where source data includes shortened opening or closing times, we preserve those local session boundaries so you can distinguish a reduced trading window from a full closure.

Timezone presentation

We present trading schedules in the exchange’s local timezone and keep the IANA timezone identifier visible on each market page. This avoids ambiguity when comparing exchanges across regions and preserves the meaning of holiday and session data in its native market context.

Operational boundary

Exchange Calendar is an informational service. It makes exchange schedules easier to inspect but does not replace official exchange notices, broker communications, or venue-level operational announcements used for time-sensitive trading decisions.
