BST (British Summer Time) is 0 hours ahead of UTC (Coordinated Universal Time). This means when it's 12:00 PM in UTC (UTC), it's 12:00 PM in London (BST).
The best time to call from UTC to BST is during overlapping business hours. For UTC callers, schedule between 9:00 AM - 12:00 PM UTC 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. Coordinated Universal Time (UTC+0) and British Summer Time (UTC+1) may have different DST schedules.
UTC includes cities like UTC. BST includes cities like London. 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.
