The Republic of India uses only one time zone across the whole nation and all its territories, called Indian Standard Time (IST), which equates to UTC+05:30, i.e. five and a half hours ahead of Coordinated Universal Time (UTC). India presently does not observe daylight saving time (DST or summer time).
