About GMT to IST
GMT to IST is a heavily searched conversion driven by the UK's longstanding business ties with India, including extensive outsourcing, finance, and technology coordination.
A note on daylight saving
The UK itself shifts to British Summer Time (BST) for part of the year, even though the search term "GMT" is commonly used year-round to refer to UK time generally. Since India has no daylight saving, the real gap is 5.5 hours in UK winter (GMT) and 4.5 hours in UK summer (BST).
Common questions
How many hours is GMT to IST?
5.5 hours in UK winter (GMT), and 4.5 hours in UK summer (when the UK shifts to BST) — India's clocks stay fixed year-round.
Is GMT the same as UK time all year?
Not technically — the UK only uses GMT in winter and shifts to British Summer Time (BST, one hour ahead) from late March to late October, though "GMT" is commonly used informally to mean UK time regardless of season.
What is a good meeting time between the UK and India?
Late morning UK time (roughly 9-11 AM) typically overlaps with early-to-mid afternoon in India (2:30-4:30 PM IST).
