States on Eastern Time
Every US state fully or partly on ET, with the split counties.
Geography · UTC−05:00
UTC−5 is five hours behind Coordinated Universal Time. Eastern Time uses it only in winter, as EST; Panama, Jamaica, Colombia, Peru, mainland Ecuador and Cancún use it all year; Chicago reaches it only on daylight time.
These places follow the US and Canadian rule: UTC−5 from the first Sunday in November, UTC−4 from the second Sunday in March, switching at 2:00 AM local time. Their winter offset is Eastern Standard Time.
Cuba normally uses UTC−5 in winter and UTC−4 in summer, changing on the US Sundays but at midnight: clocks jump from midnight to 1:00 AM in March and fall back from 1:00 AM to midnight in November. In late October 2026, citing its electricity crisis, the government cancelled the November 1 fall-back. Cuba stays on UTC−4 until November 7, 2027, so this winter Havana is an hour ahead of New York and Miami, and phones with older time zone data may show it an hour too early.
From November to March these places share New York's clock; from March to November they share Chicago's. That flip catches travellers out: a 9:00 AM meeting in Bogotá is 9:00 AM in New York in January but 10:00 AM in New York in July.
Why don't they change clocks? Most of these countries lie within 20° of the equator, where day length barely moves. Quito's day lasts about 12 hours 7 minutes all year, while New York's runs from about 9 hours 15 minutes in December to 15 hours 6 minutes in June. Shifting the clock gains little when sunrise is near 6:00 AM in every season.
Some places reach UTC−5 only on daylight time:
So in July "UTC−5" means Chicago, Bogotá, Lima and Cancún, while New York has moved on to UTC−4. A schedule that says "UTC−5" in summer does not mean Eastern Time.

Because of longitude. The Earth turns 15° an hour, so the meridian at 75°W is where the sun is highest at noon on a UTC−5 clock, and the natural band for that offset runs from 67.5°W to 82.5°W. South America's Pacific coast lies almost directly south of the US East Coast: Lima, at 77.04°W, is on practically the same meridian as Washington D.C., and Bogotá sits just west of New York's longitude. Panama, Jamaica, Ecuador and Peru lie almost entirely inside the same band.
Some members chose UTC−5 against the sun. Cancún, near 87°W, is closer to the Central meridian; Quintana Roo moved an hour ahead in 2015 to give tourists longer evenings. Atikokan, at almost 92°W, has long kept EST by local choice, and Winnipeg, at 97°W, joined UTC−5 in 2026. At the other end, Rio Branco in Acre (67.8°W) sits right on the band's eastern edge.
The offset itself and how it is written are covered on the Eastern Time UTC offset page.
The IANA time zone database contains fixed-offset zones named Etc/GMT+5, Etc/GMT-5 and so on, and their signs are reversed. Etc/GMT+5 is five hours behind UTC, the offset of Bogotá and of New York in winter. Etc/GMT-5 is UTC+5, the time in Pakistan.
The reason is historical. These names follow the POSIX TZ convention, which counts hours to be added to local time to reach UTC, so places west of Greenwich get a positive number; the same convention gives US Eastern Time the rule string EST5EDT. ISO 8601 and everyday usage do the opposite and write -05:00.
Two more traps sit nearby. The legacy ID EST is now an alias of America/Panama: fixed UTC−5 with no daylight saving, so it is wrong for New York most of the year. And a fixed offset cannot follow rule changes. Store the city-based zone, such as America/New_York, America/Bogota or America/Cancun, and keep numeric offsets for timestamps that record a single instant. Check the live Eastern Time clock to see which offset New York is on today.
From early November to mid-March, yes: both are on UTC−5. The rest of the year New York is on EDT and Bogotá is one hour behind it, the same as Chicago.
Only in winter. Quintana Roo keeps UTC−5 all year, so from March to November Cancún is one hour behind Miami.
All year: Panama City, Kingston, Bogotá, Quito, Lima and George Town (Cayman Islands). In winter only: Washington D.C., Ottawa, Nassau, Port-au-Prince and Cockburn Town (Turks and Caicos), which move to UTC−4 for daylight saving.
Yes, for everyday purposes. GMT and UTC differ by less than a second, so GMT−5 and UTC−5 name the same offset. Only the IANA Etc/GMT names reverse the sign.
Yes. The Sunshine Protection Act would keep Eastern Time on UTC−4 all year. The House passed it on July 14, 2026; as of late 2026 the Senate has not voted, so EST (UTC−5) still returns every November.
