GFT (French Guiana Time) is 3 hours behind BST (British Summer Time). This means when it's 12:00 PM in London (BST), it's 9:00 AM in Cayenne (GFT).
The best time to call from BST to GFT is during overlapping business hours. For BST callers, schedule between 12:00 PM - 5:00 PM BST to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. British Summer Time (UTC+1) and French Guiana Time (UTC-3) may have different DST schedules.
BST includes cities like London. GFT includes cities like Cayenne. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
