Using MarketClock

No account is needed for anything. Nothing personal is stored.

Markets

The markets list shows all 30 markets with flags and a search box. Each market page shows its country, timezone, weekend, session hours (with the exchange page they came from) and whether it is open right now, with a countdown to the next close or open in exchange time.

Calendars

• /markets/XNYS/2027: one market's year, with closures, early closes and weekends.
• /holidays/2027: every market's closures in one year.
• Subscribe: each market has an iCalendar feed (/api/v1/markets/XNYS/calendar.ics) for Google Calendar, Apple Calendar or Outlook. It always covers this year and next.
• Download: /api/v1/markets/XNYS/holidays.csv?year=2027.
