Time

  • Most of Colorado, Wyoming, Montana, Idaho, Utah, New Mexico and Arizona follow Mountain Standard Time (GMT/UTC minus seven hours). California, Nevada, Oregon and Washington generally follow Pacific Standard Time (GMT/UTC minus eight hours). There are some variations within a state, usually based on location or season.
  • Daylight Saving Time pushes the clocks ahead an hour. It runs from the second Sunday in March to the first Sunday in November.
  • Arizona does not observe daylight-saving time; during that period it's one hour behind other Southwestern states. The Navajo Reservation, which lies in Arizona, New Mexico and Utah, does use daylight-saving time. The Hopi Reservation, which is surrounded by the Navajo Reservation in Arizona, follows the rest of Arizona.
  • The US date system is written as month/day/year. Thus, the 8th of June, 2008, becomes 6/8/08.
