When do WAT and US Eastern Time working hours overlap?

Is EST 5 or 6 hours behind WAT?
Both, depending on the season. Strictly, EST (winter) is 6 hours behind WAT and EDT (summer) is 5 hours behind. When someone writes "EST" between March and November they usually mean the current New York time, which is EDT, so plan for 5 hours.
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.

If both of you keep a 9 AM to 5 PM weekday, the shared window is 2 PM to 5 PM WAT time in summer (3 PM to 5 PM in winter). Put calls near the middle of it so nobody joins tired or rushed.
