FAQs

1. How to convert UTC to GMT?
   • UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are essentially the same time standard, so there is no need to convert between them. They are often used interchangeably.
2. What time is UTC in the UK now?
   • The UK observes GMT (Greenwich Mean Time) during standard time and BST (British Summer Time) during daylight saving time. The current time in the UK depends on the time of year and whether daylight saving time is in effect.
3. Is UTC and GMT the same time zone?
   • Yes, UTC and GMT are essentially the same time zone. GMT used to be based on the position of the sun at the Prime Meridian (0 degrees longitude) in Greenwich, London. UTC is a more precise time standard, but for practical purposes, they are considered equivalent.
