To convert UTC to EST, subtract 5 hours from UTC time. During Daylight Saving Time (from the second Sunday in March to the first Sunday in November), subtract 4 hours instead. For example, 15:00 UTC is 10:00 EST and 11:00 EDT.

Questions and answers

  1. What is the difference between EST and EDT?

    EST (Eastern Standard Time) is UTC-5 and is used during the non-daylight savings months, while EDT (Eastern Daylight Time) is UTC-4 and is used during Daylight Saving Time.

  2. When does Daylight Saving Time start and end for EST/EDT?

    Daylight Saving Time starts on the second Sunday in March and ends on the first Sunday in November for the EST/EDT time zone.

  3. How do I convert UTC to EST outside of Daylight Saving Time?

    To convert UTC to EST when Daylight Saving Time is not in effect, subtract 5 hours from the UTC time.

  4. Why do we subtract 4 hours during Daylight Saving Time?

    During Daylight Saving Time, clocks are set forward by one hour to make better use of daylight, so the offset from UTC changes from -5 to -4 hours.
