What is 1 AM EST in GMT?

Does the answer change during the year?

Yes. Eastern Time and Greenwich Mean Time don't change their clocks on the same dates, so over the next 12 months:

• October 14 to October 31: 1 AM EST = 5 AM GMT
• November 1 to March 13: 1 AM EST = 6 AM GMT
• March 14 to October 13: 1 AM EST = 5 AM GMT

Eastern Time switches between EST and EDT for daylight saving time; people often say EST all year.
