GMT to EST
The quick answer: EST is five hours behind GMT. The accurate answer needs a date, which is what the preset converter below is for.
Guide
How to use it
- The converter is preset UTC/GMT to New York.
- If by "GMT" you mean UK clock time (which runs BST in summer), switch the from-zone to London.
- Set the date and read the result, the abbreviation shown (EST or EDT) tells you which regime New York is in.
Examples
The five-hour rule and its exceptions
The textbook case: winter, both sides on standard time, five hours apart. Noon GMT is 7am in New York, pre-coffee but answerable.
Summer New York runs EDT (UTC−4). If you also mean "London" by GMT (which is then BST, UTC+1), the practical gap stays five, two errors cancelling is how most people survive.
Mid-March and early November: the US has switched, the UK has not (or vice versa). London-New York is briefly four hours, and "GMT to EST" questions spike for exactly this reason.
Method
How it works
GMT here is offered as true UTC (constant, no DST) with London one click away for UK clock time, the distinction is the source of most GMT confusion. New York renders as EST (UTC−5) or EDT (UTC−4) by date, from the IANA rules.
The strip shows both days hour by hour, so the whole "what time is their afternoon" question answers itself visually.
