How Exchange Calendar Works

Methodology
A lightweight explanation of what the site covers, how status is derived, and how to interpret half days and timezone-aware schedules.

What the site covers

Exchange Calendar tracks stock-exchange trading hours, market holidays, half days, and local exchange timezones. The focus is practical decision support for investors and traders rather than broad educational finance content.

How market status is derived

Current status is derived from each exchange’s local timezone, its weekday session schedule, and same-day holiday overrides. A market can appear as open, closed, holiday, or half day depending on the combination of those inputs.

How half days are handled

Half days are treated separately from full closures and are surfaced anywhere upcoming holiday schedules are shown. When available, the local opening and closing session times are retained so users can understand the shortened trading window.

Timezone policy

Trading hours are presented in the exchange’s local timezone and each market page keeps the IANA timezone identifier visible. This avoids ambiguity when comparing schedules across regions.

Informational use

This site is informational and does not provide investment advice. Users should verify critical holiday or session decisions against official exchange notices when precision is required for trading operations.
