What is GMT?
GMT, or Greenwich Mean Time, is at UTC +0. The United Kingdom, Ireland, Iceland, and some countries in West Africa use it. GMT is a reference time for the world. It stays the same all year, but the UK does use British Summer Time (BST) in the summer.
What is IST?
IST, or Indian Standard Time, is at UTC +5:30. All of India and Sri Lanka use it. IST doesn't change for daylight saving time, so it's the same all year.

IST is 5 hours and 30 minutes ahead of GMT. For example:
- 12:00 PM GMT → 5:30 PM IST
