What is 12 PM GMT in EST?

Does the answer change during the year?

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

• October 14 to October 31: 12 PM GMT = 8 AM EST
• November 1 to March 13: 12 PM GMT = 7 AM EST
• March 14 to October 13: 12 PM GMT = 8 AM EST

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