45 views

UTC (Universal Time Coordinated) is the primary time standard by which the world regulates clocks and time. It's not adjusted for daylight saving time, making it a constant time standard worldwide. On the other hand, EST (Eastern Standard Time) is a time zone used in parts of North America and is 5 hours behind UTC (UTC-5). During Daylight Saving Time, which starts in the spring and ends in the fall, EST shifts to EDT (Eastern Daylight Time), becoming only 4 hours behind UTC (UTC-4).
