Mountain Time is a time zone in North America that is seven hours behind Coordinated Universal Time (UTC-7) during standard time and six hours behind (UTC-6) during daylight saving time. It covers parts of the western United States, including states like Colorado, Utah, and New Mexico, as well as some regions in Canada. Daylight saving time typically begins on the second Sunday in March and ends on the first Sunday in November. During this period, clocks are set forward one hour, allowing for more daylight in the evenings. This practice helps to make better use of natural daylight and conserve energy.
