A time zone is a standard time used in a geographic area. It's the time we've all agreed to follow so it's easier to travel, communicate and barter with people around the world.

These lines aren't straight and neat, many are negotiated and agreed based on the country's needs.

Mountain Time Zone (MT) consists of places that use:

- Mountain Standard Time

- Mountain Daylight Time

Mountain time zones can either be Standard or Daylight depending if the region using the zone observes daylight savings time during spring and summer seasons.

Mountain Standard Time or MST for short is 7 hours behind Coordinated Universal Time (UTC - 7:00). During the months when daylight savings is observed, Mountain time zone changes to Mountain Daylight Time or MDT which is 6 hours behind Universal Time (UTC -06:00).

This means that the time zones leveraged in mountain time zone regions are 7 places behind the starting line of Greenwich.
