Despite its large size, India follows a single time zone, called the Indian Standard Time (IST). IST maintains a 30 minute offset from UTC. This means that when it is 12:00 UTC, it is 5:30 AM anywhere in India. This can be particularly confusing to travelers who are accustomed to integer time zone changes.
