Best Time to Call the UK from India
India's offset of UTC+5:30 does not change, so the gap with the UK moves by an hour when the UK changes its clocks.
In UK winter (GMT)
India is 5.5 hours ahead. UK 09:00 is 14:30 in India, and UK 13:00 is 18:30. The overlap with the end of the Indian working day is therefore the UK morning to early afternoon.
In UK summer (BST)
India is 4.5 hours ahead. UK 09:00 is 13:30 in India, and UK 14:00 is 18:30. You gain half an hour of overlap compared with winter.
Tips
Write meeting times as 'UK time' and add the Indian time in brackets, for example 10:00 UK (15:30 IST). Be careful with 'IST', which also means Irish Standard Time in the UK summer.
