Scheduling Across GMT and WAT
For professionals scheduling meetings between GMT and WAT, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 1 hour difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
GMT observes Daylight Saving Time, switching to BST (UTC+1) during summer months. WAT does not observe DST, staying at UTC+1 year-round. During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
