Questions
What’s the time difference between the UK and India?
India Standard Time (UTC+5:30) is 5 hours 30 minutes ahead of GMT. From the last Sunday in March to the last Sunday in October the UK is on BST (UTC+1), and India is 4 hours 30 minutes ahead. India has no daylight saving time, so only the UK’s clock changes move the gap.
When are both offices open?
In the UK morning. With 9-to-5 days, 9:00 to 11:30 AM GMT is 2:30 to 5:00 PM in India; in summer, 9:00 AM to 12:30 PM BST is 1:30 to 5:00 PM IST. Afternoon meetings in London land after the working day in India.
Is UTC to IST the same as GMT to IST?
In winter, yes: UTC and GMT are both UTC+0, so IST is 5 hours 30 minutes ahead of either. In summer UK time moves to UTC+1, but UTC itself never changes, so UTC to IST stays 5 hours 30 minutes all year.
