India uses India Standard Time (IST), which is UTC+5:30 hours.

India does not observe Daylight Saving Time. The country remains on IST, UTC+5:30, throughout the year.

The UTC+5:30 distinction stems from historical decisions made during British colonial rule to establish a single standard time for administrative convenience. Geographically, the nation spans a wide longitudinal range, and the chosen standard meridian (82.5 degrees east) is roughly central, providing a balanced equilibrium for the entire nation. This half-hour offset is a compromise that accommodates the vast country's needs while maintaining administrative simplicity.

IST is unique and is 30 minutes ahead of Pakistan Standard Time (PST, UTC+5) and 15 minutes behind Nepal Time (NPT, UTC+5:45).
