Unix Timestamp to IST — Indian Standard Time Converter
Convert Unix timestamps to Indian Standard Time (IST, UTC+5:30) and vice versa. IST is used throughout India and does not observe daylight saving time. Essential for developers working with Indian services, APIs, and databases.
What is Indian Standard Time?
IST (Indian Standard Time) is UTC+5:30, the time zone used across India. It does not change for daylight saving time. Converting Unix timestamps to IST is common when working with Indian services and users.
Why Use This Tool
- API debugging — Convert API timestamps to readable IST.
- Log analysis — Translate server logs to local Indian time.
- Database queries — Convert stored timestamps for display.
- Scheduling — Plan events in IST from epoch times.
- Cross-timezone work — Coordinate between UTC/US times and IST.
Tips
- IST = UTC + 5 hours 30 minutes.
- India has no daylight saving time.
- Use "Asia/Kolkata" in code for IST.
- Timestamps are in seconds (not milliseconds).

Frequently Asked Questions
What is the IST offset?
IST is UTC+5:30 (5 hours and 30 minutes ahead of UTC). This offset never changes as India does not observe daylight saving time.
Does IST have daylight saving?
No. India does not observe daylight saving time, so IST is always UTC+5:30 year-round.
How do I handle IST in code?
Use the IANA timezone identifier "Asia/Kolkata" for IST in most programming languages and libraries.
Is IST the same as Asia/Kolkata?
Yes. "Asia/Kolkata" is the IANA timezone database identifier for Indian Standard Time.
