Current Time in GMT − 5 Zone
About GMT-5
GMT-5 is five hours behind Greenwich Mean Time. It is known as Eastern Standard Time (EST) in North America, serving cities like New York, Toronto, and Miami in the winter. It is also used year-round by Colombia, Peru, and Ecuador. It is heavily affected by DST in North America.
UTC Offset: GMT-5
What is GMT-5?
GMT-5 means Greenwich Mean Time 5 hours behind the Greenwich meridian, the historical reference line running through the Royal Observatory in London. GMT offsets are the everyday way many countries, broadcasters, and travel timetables describe their local time relative to the UK.
Note that some of the countries listed below sit on GMT-5 for only part of the year: when daylight saving time starts or ends they move one hour, so always check the live local times shown on this page or on each country's own page.
GMT-5 vs UTC-5
For everyday purposes GMT-5 and UTC-5 are the same wall-clock time. GMT is the traditional name based on mean solar time at Greenwich, while UTC is the modern atomic-time standard used by computers and aviation. If you are setting a meeting or catching a flight, either works; if you are configuring a server, use UTC-5.

GMT-5: The Fixed Offset and Its Dynamic Time Zone Landscape
GMT-5 is a fixed UTC offset of five hours behind Coordinated Universal Time. Unlike named time zones such as Eastern Standard Time (EST) or Colombia Time (COT), GMT-5 is simply a numerical offset that does not observe daylight saving time on its own. However, many regions that use this offset during standard time shift to GMT-4 when daylight saving is in effect, meaning the list of countries and territories at GMT-5 changes seasonally. This article explores the fixed offset, the regions that use it, and practical scheduling considerations.
Fixed Offset vs. Named Time Zone
A fixed UTC offset like GMT-5 is a constant number of hours behind UTC. It does not change with seasons. In contrast, a named time zone (e.g., Eastern Standard Time) typically includes rules for daylight saving time, so its offset varies between standard and daylight time. For example, New York uses EST (GMT-5) in winter and EDT (GMT-4) in summer. Therefore, while GMT-5 is always the same, the regions that are at GMT-5 at a given moment depend on whether they observe DST and what season it is.
Regions Currently on GMT-5 (Standard Time)
The following countries and territories use GMT-5 as their standard time offset (non-DST periods). Note that some of these regions switch to GMT-4 during daylight saving time, so they are only on GMT-5 part of the year.
- Bahamas (observes DST, switches to GMT-4 in summer)
- Brazil (parts: Acre, Amazonas west of the Purus River, Rondônia, Roraima? Actually, Brazil uses GMT-5 in some western areas, but note that Brazil no longer observes DST. The zones America/Eirunepe and America/Rio_Branco are GMT-5 year-round.)
- Canada (parts: mostly Nunavut east of 85°W, Ontario west of 90°W? Actually, Canada uses GMT-5 in areas like Southampton Island (America/Atikokan) and some parts of Ontario and Quebec near the border. Many Canadian regions observe DST, so they switch.)
- Cayman Islands (no DST, always GMT-5)
- Chile (Easter Island uses GMT-5? Actually, Easter Island is GMT-6 standard, GMT-5 DST. Mainland Chile uses GMT-4 standard, GMT-3 DST. So Chile is not on GMT-5 standard. But the article says Chile is on this offset? Let's check: Chile has America/Santiago (GMT-4 standard, GMT-3 DST) and Pacific/Easter (GMT-6 standard, GMT-5 DST). So Easter Island uses GMT-5 during DST. But the country list includes Chile, so perhaps they mean Easter Island during DST. But the offset page is for GMT-5, so we include it as a region that uses GMT-5 part of the year.)
- Colombia (no DST, always GMT-5)
- Cuba (observes DST, switches to GMT-4 in summer)
- Ecuador (mainland and Galápagos? Mainland is GMT-5 year-round; Galápagos is GMT-6 year-round. So Ecuador is always GMT-5 except Galápagos.)
- Haiti (observes DST, switches to GMT-4 in summer)
- Jamaica (no DST, always GMT-5)
- Mexico (parts: Quintana Roo (Cancun) is GMT-5 year-round; other areas like Mexico City are GMT-6 standard, GMT-5 DST. So parts of Mexico use GMT-5 during DST.)
- Panama (no DST, always GMT-5)
- Peru (no DST, always GMT-5)
- Turks & Caicos Islands (observes DST, switches to GMT-4 in summer)
- United States (parts: Eastern Time zone observes DST, so GMT-5 in winter; also some areas like parts of Indiana that do not observe DST? Actually, most of Indiana observes DST, but some counties in the Chicago area are on Central Time. The IANA zones listed include America/Detroit, America/Indiana/Indianapolis, etc., which are all on Eastern Time and observe DST, so they are GMT-5 only during standard time. Also, America/Atikokan is in Canada but is a fixed GMT-5 zone without DST.)
Representative Cities and IANA Zones
The IANA Time Zone Database includes many zones that use GMT-5 during standard time. Some are fixed (no DST), while others switch. Key zones include:
- America/Atikokan (Canada, fixed GMT-5)
- America/Bogota (Colombia, fixed GMT-5)
- America/Cancun (Mexico, fixed GMT-5)
- America/Cayman (Cayman Islands, fixed GMT-5)
- America/Detroit (USA, DST, GMT-5 standard)
- America/Eirunepe (Brazil, fixed GMT-5)
- America/Grand_Turk (Turks & Caicos, DST)
- America/Guayaquil (Ecuador, fixed GMT-5)
- America/Havana (Cuba, DST)
- America/Indiana/Indianapolis (USA, DST)
- America/Jamaica (Jamaica, fixed GMT-5)
- America/Lima (Peru, fixed GMT-5)
- America/Nassau (Bahamas, DST)
- America/New_York (USA, DST)
- America/Panama (Panama, fixed GMT-5)
- America/Port-au-Prince (Haiti, DST)
- America/Rio_Branco (Brazil, fixed GMT-5)
Representative cities in these zones include: Atikokan, Bogota, Cancun, George Town (Cayman), Detroit, Eirunepe, Grand Turk, Guayaquil, Havana, Indianapolis, Kingston (Jamaica), Lima, Nassau, New York, Panama City, Port-au-Prince, Rio Branco, and many others.
Practical Scheduling Notes
When scheduling across GMT-5, remember that many regions observe DST. During the summer months (typically March to November in the Northern Hemisphere), places like New York, Toronto, Havana, and Nassau shift to GMT-4. So a meeting at 10:00 AM in New York in July is 10:00 AM EDT (GMT-4), not GMT-5. Meanwhile, Colombia, Peru, Panama, and Jamaica remain at GMT-5 year-round. Always check the current offset for the specific location.
Military and aviation time uses letter codes: GMT-5 corresponds to Romeo time (R). Zulu time is GMT+0. Remember that UTC and GMT are functionally identical for everyday timekeeping, but UTC is the scientific standard.
Summary
GMT-5 is a fixed offset that serves as the standard time for many regions in the Americas, from Canada to Peru. However, due to daylight saving time, the set of places actually using GMT-5 at any given moment changes. For accurate scheduling, always confirm whether the location is currently on standard time or daylight time.
Frequently Asked Questions
What is the difference between GMT-5 and Eastern Standard Time (EST)?
GMT-5 is a fixed offset of 5 hours behind UTC. Eastern Standard Time (EST) is a time zone that uses GMT-5 during standard time, but switches to Eastern Daylight Time (EDT, GMT-4) during daylight saving time. So EST is a subset of GMT-5, but not all GMT-5 regions use EST.
Which countries are always on GMT-5 without daylight saving time?
Countries that remain on GMT-5 year-round include Colombia, Ecuador (mainland), Jamaica, Panama, Peru, and the Cayman Islands. Also, parts of Brazil (e.g., Eirunepe and Rio Branco) and Canada (Atikokan) are fixed at GMT-5.
Does New York City use GMT-5 all year?
No. New York City uses Eastern Standard Time (GMT-5) from early November to mid-March, and Eastern Daylight Time (GMT-4) from mid-March to early November. So it is only on GMT-5 part of the year.
What is the military letter code for GMT-5?
The military letter code for GMT-5 is Romeo (R). Zulu (Z) is used for GMT+0.
How do I convert GMT-5 to my local time?
If you know your UTC offset, subtract the difference. For example, if you are at GMT+1, add 6 hours to GMT-5 to get your time. Always check if the GMT-5 location is observing daylight saving time, as it might actually be at GMT-4.
Why are there so many IANA zones for GMT-5?
The IANA Time Zone Database includes many zones to reflect historical and political differences in timekeeping, even if they share the same offset. For example, America/New_York and America/Detroit both use GMT-5 in winter, but have different histories of DST observance. This allows for accurate local time calculations.
