What GMT and IST mean here
GMT (Greenwich Mean Time) is UTC+0 and never changes. The UK only uses GMT in winter: from March 29 to October 25, 2026 London is on BST (British Summer Time, UTC+1). If you want the actual time in the UK, use a London page instead; this page converts strict GMT.
IST here means India Standard Time, UTC+5:30, used across all of India with no daylight saving time. The half hour means India is never a whole number of hours away from the US or UK. IST is also used for Israel Standard Time (UTC+2) and Irish Standard Time (Ireland's summer time, UTC+1); to convert those, search for Tel Aviv or Dublin.
