Convert US Eastern Time to Coordinated Universal Time
Converts US Eastern Time (EST/EDT) to Coordinated Universal Time (UTC). Eastern Time is UTC-5 during standard time and UTC-4 during daylight saving time. UTC is the global time standard used as the reference for all other time zones.
This tool uses Intl.DateTimeFormat with IANA timezone data, so it automatically handles daylight saving time transitions.
EST (Eastern Standard Time) is UTC-5, used from November to March. EDT (Eastern Daylight Time) is UTC-4, used from March to November. This tool handles the switch automatically.
EST is always UTC-5. However, the US Eastern time zone switches to EDT (UTC-4) during daylight saving time. This tool accounts for that.
New York, Washington DC, Miami, Atlanta, Toronto, and Montreal are all in the Eastern time zone.
