Universal Time Conversion Chart
Coordinated Universal Time (UTC) is the time at Earth's zero or reference meridian, which is located on the globe at Greenwich, England. Progressing around the globe from the meridian, time changes one hour with each change of 15 degrees in longitude. The five time zones in the mainland United States roughly follow those longitude lines. Use the chart below to convert local times to and from universal time.
