Indian agencies, outsourcing firms and software teams often hire or partner with Nigerian talent. India is one of the few big zones with a half-hour offset, so the gap is never a round number. Right now IST is 4 hours 30 minutes ahead of WAT all year.

Frequently asked questions
What is the time difference between WAT and IST?
IST is 4 hours 30 minutes ahead of WAT all year. Neither side uses daylight saving time, so the gap never changes.
What is 3 PM WAT in IST time?
3 PM in WAT is 7:30 PM in IST.
When do WAT and IST working hours overlap?
On weekdays, a 9 AM to 5 PM day overlaps from 9 AM to 1 PM (WAT time). Use the meeting planner to stretch the day or add more cities.
Why is India time 30 minutes off?
India uses a single zone, IST, set at UTC+5:30 so it sits in the middle of the country. That makes it 4 hours 30 minutes ahead of Nigeria all year, and neither country uses daylight saving.
Does this tool handle daylight saving time?
Yes. It uses your browser's built-in time zone database (the IANA database that phones and computers use), so summer and winter time changes are applied for the exact date you pick. Nigeria (WAT, UTC+1) never changes its clocks, but the US, Canada, the UK and Europe do, so the gap to them moves by one hour twice a year.
Best time to talk between WAT and IST
If both of you keep a 9 AM to 5 PM weekday, the shared window is 9 AM to 1 PM WAT time. Put calls near the middle of it so nobody joins tired or rushed. Need three or four cities? Use the meeting planner. Want everyone to see the time in their own zone? Share your working-hours link.
