GMT to IST Time Converter
This page converts Greenwich Mean Time (UTC) (GMT) to India Standard Time (IST). India is 5 hours 30 minutes ahead of GMT all year. Neither zone changes its clocks relative to the other, so the difference never moves.
Pick a date and time above for an exact conversion that accounts for daylight saving, or use the table below for a quick look-up.
