You can convert any time listed in GMT to EST by subtracting 5 hours, which means that at 2 p.m. GMT it would be 9 a.m. EST. Greenwich Mean Time, commonly abbreviated as GMT, is the world standard time keeper, and is also referred to as UTC (Coordinated Universal Time). Keep in mind that during the summer months when daylight savings time is in effect, the difference between GMT and EST/EDT is only four hours, instead of five.
- Take note of the time given in GMT
Write down your time as given in GMT. You want to convert 2 p.m. GMT.
- Subtract the appropriate amount of hours from GMT
You want to convert 2 p.m. GMT to EST so you need to subtract 5 hours from 2 p.m. GMT. If you wanted to convert to EDT (generally in effect in the US from March until November), you would only subtract 4 hours from 2 p.m. GMT.
- Record your time in EST
When you subtract 5 hours from 2 p.m. GMT, you arrive at 9 a.m. EST.
