IST to UTC converter
UTC never changes for daylight saving time, and neither does India Standard Time, so this gap stays the same all year.

UTC is 5 hours 30 minutes behind India Standard Time all year.
Right now IST is UTC+5:30 and UTC is UTC+0. Neither changes its clocks, so this never changes.

UTC: Coordinated Universal Time
Coordinated Universal Time is UTC+0.
