EST to UTC Converter
US Eastern Time to Coordinated Universal Time: live clocks, today's full conversion table, and the best hours to call. Daylight saving is handled automatically.
About EST and UTC
US Eastern Time (EST/EDT) is used in New York, Washington DC, Boston, Atlanta, Miami and Toronto. Clocks shift to EDT (daylight time) from March to November.
Coordinated Universal Time (UTC) is the global reference clock used in aviation, servers and log files. UTC never changes for daylight saving.
Time difference between EST and UTC
UTC is 5 hours ahead of EST in winter (January) and 4 hours ahead of EST in summer (July), because of daylight saving changes. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.
Best hours for meetings
Scan the table for rows where both sides land inside working hours (9:00 to 18:00). Rows where one side is early morning or late evening are workable for a quick call; avoid rows where either side is in the middle of the night. To line up three or more cities at once, use the time zone converter and meeting planner.
