UTC to IST Converter
Coordinated Universal Time to India Standard Time: live clocks, today's full conversion table, and the best hours to call. Daylight saving is handled automatically.
About UTC and IST
Coordinated Universal Time (UTC) is the global reference clock used in aviation, servers and log files. UTC never changes for daylight saving.
India Standard Time (IST) is used across all of India, including Mumbai, Delhi, Bengaluru, Chennai and Kolkata. India does not observe daylight saving time.
Time difference between UTC and IST
IST is 5 hours 30 minutes ahead of UTC throughout the year. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.
Best hours for meetings
Scan the table for rows where both sides land inside working hours (9:00 to 18:00). Rows where one side is early morning or late evening are workable for a quick call; avoid rows where either side is in the middle of the night. To line up three or more cities at once, use the time zone converter and meeting planner.
