Yes, if either time zone observes DST, the offset between them may change by 1 hour during spring and autumn transitions (typically March/April and October/November). The table above shows the current offset. Use the live clocks at the top of this page for real-time accuracy, or check our interactive converter for custom dates.
How do I convert EST to UTC manually?
Add 4 hours to the EST time. For example, 2:00 PM EST + 4 hours = 6:00 PM UTC. If the result is 24 or more, subtract 24 and add one day. If negative, add 24 and subtract one day.
