Frequently asked questions
What is the IST time now?
The clock above shows the exact current time in IST (India Standard Time, UTC+05:30). It is synced with internet time and updates every second, so you can read the time with seconds.
What is IST?
IST stands for India Standard Time. It is the one time zone used across all of India and is 5 hours 30 minutes ahead of UTC. Its IANA time zone identifier is Asia/Kolkata, the name phones, computers and calendar apps use for it. Note that IST can also mean Irish Standard Time (UTC+1 in summer) or Israel Standard Time (UTC+2). This page is for India.
Does India use daylight saving time?
No. India stays on IST all year, so the time never changes in spring or autumn. The gap to countries that do change their clocks, such as the USA and the UK, shifts by one hour twice a year.
How do I convert IST to EST?
Subtract 9 hours 30 minutes while New York is on daylight time (roughly March to November) and 10 hours 30 minutes in winter. For example, 6 PM IST is 8:30 AM in New York in summer and 7:30 AM in winter. The IST to EST converter does the maths for any date.
Why is IST 5 hours 30 minutes ahead of UTC?
India uses a single time zone based on the 82.5° East meridian, which is 5.5 hours of sun time ahead of Greenwich. That is why the offset ends in a half hour.
Which cities use IST?
Every city in India, including Delhi, Mumbai, Kolkata, Chennai, Bengaluru and Hyderabad, shows the same time.
