About

Regular Trading Hours is a single-page reference for the world's trading day. It exists because every quotes site shows you a price, but almost none of them clearly answer the simpler question: is this market actually open right now, and if not, when will it be?

Principles

• No ads. Nothing on the page tries to sell you anything.
• No accounts. No signup, no email collection, no logins.
• No tracking. No analytics, no third-party scripts, no fingerprinting.
• No JavaScript heavy lifting. The page renders fast on a five-year-old phone over a weak connection.
• One purpose. Trading hours and live status. That's it.

How the times work

Each market's hours are stored in its own local time and IANA timezone. The browser uses Intl.DateTimeFormat to convert to the right local clock, which means daylight-saving transitions are handled automatically - no manual updates twice a year.

Holidays

The 2026 holiday calendar is baked into the page. It covers approximately ten to twenty full-day closures for the major exchanges. Half-days (early closes) are not flagged - those markets show as fully open, which is the more conservative default.

Watchlist

Stars are stored in your browser's localStorage. Nothing leaves your device. Clearing browser data will reset the watchlist.
