Why people convert Lagos to GMT time
- Scheduling a call from Lagos to GMT: a 10:00 AM start in Lagos lands at 9:00 AM in GMT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Lagos and GMT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM WAT time (9:00 AM–4:00 PM GMT). That is roughly 7 hours of usable overlap.
- Coordinating a Lagos-based team with GMT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM WAT" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM WAT as the recurring meeting window if you work primarily from Lagos and need GMT colleagues present.
