Understanding the -3h Gap: EAT vs GMT

Why people convert EAT to GMT time
- Scheduling a call from EAT to GMT: a 10:00 AM start in EAT lands at 7:00 AM in GMT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both EAT and GMT are inside the 9-to-5 working day between 12:00 PM and 5:00 PM EAT time (9:00 AM–2:00 PM GMT). That is roughly 5 hours of usable overlap.
- Booking travel or deliveries: tracking GMT local time against EAT keeps pickup windows and arrival estimates honest across the -3h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM EAT" is unambiguous; "3 PM" across a -3h gap is not.
- Block 12:00 PM–5:00 PM EAT as the recurring meeting window if you work primarily from EAT and need GMT colleagues present.

About GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude).

The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

Both EAT and GMT sit inside the 9 AM – 5 PM working day between 12:00 PM–5:00 PM EAT, which is 9:00 AM–2:00 PM GMT. That gives roughly 5 hours of shared time — the safest window for a live call or meeting.
