Early Close Time in Mountain Time
On early close days, markets close at 1:00 p.m. ET instead of 4:00 p.m. ET. In MT, that's 11:00 AM. Early closes occur on Black Friday, Christmas Eve, and the day before Independence Day.
Daylight Saving Time Impact
Most of the Mountain Time zone observes daylight saving. In winter (MST, UTC-7), the market opens at 7:30 a.m. and closes at 2:00 p.m. In summer (MDT, UTC-6), times remain the same locally. Note: Arizona (except the Navajo Nation) does not observe DST — during summer, Arizona effectively aligns with Pacific Time for market hours.
Next Market Holiday
The next scheduled market closure is Thanksgiving on November 26, 2026. See full holiday schedule →
