About EST to GMT Conversion

Last updated: April 2026

Converting time between EST and GMT requires understanding their time zone offsets and any daylight saving time adjustments. EST (EST) operates at UTC-4, while GMT (GMT) is set to UTC+1. This means GMT is 5 hours ahead EST. For example, when it's 7:55 AM EST on May 5, 2026, it's 12:55 PM GMT in GMT. Both America/New_York and Europe/London observes daylight saving time, switching between EST (UTC-5) and EDT (UTC-4). Keep this in mind when converting times, especially during the spring and fall transition periods. Use this converter to quickly find the equivalent time in GMT for any time in EST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
