🇮🇳 Time Zones in India
India uses a single time zone (IST, UTC+5:30) despite spanning what would naturally be two time zones. The 30-hour offset is one of the most distinctive in the world — only a few countries use half-hour offsets. India's IT industry operates on IST, and the 10.5-hour difference with US Eastern Time means most trans-Pacific calls happen in India's evening.

Time in Daily Life
India uses a single time zone, UTC+5:30, shared by Mumbai, Delhi, and Kolkata, so the entire country runs on one half-hour-offset clock with no daylight saving.
The uniformity is practical for a vast population, though the western state of Gujarat and the far east can see the sun several hours apart while the clock stays the same.
Office hours in Bangalore and Mumbai commonly run 09:30 to 18:30, and the film and tech industries keep late schedules, with dinners often after 21:00.
