United States Time Zones

The U.S. has four time zones, ranging from Coordinated Universal Time -4 hours on the east coast to -7 hours on the west coast. The time zones are:

  • Eastern Standard Time (EST): -4
  • Central Standard Time (CST): -5
  • Mountain Standard Time (MST): -6
  • Pacific Standard Time (PST): -7

For example, when it is 1 pm in Los Angeles, it is already 4 pm in New York City. For the U.S. government's official time zone clock, click on:
