The US stock market opens at 7:00pm IST during US daylight saving and 8:00pm IST when the US is on standard time. This guide lays out both windows, explains why the time shifts even though India's clock never moves, and links out to the mechanics of pre-market and after-hours trading.
What time does the US market open in IST?
What time does the US stock market open in India (IST)?
The NYSE and Nasdaq run their regular session from 9:30am to 4:00pm Eastern time, five days a week.
India Standard Time is fixed at UTC+5:30 all year, so the IST equivalent depends entirely on which US clock is currently in effect.
US daylight time (EDT, UTC-4): the market opens at 7:00pm IST and closes at 1:30am IST.
US standard time (EST, UTC-5): the market opens at 8:00pm IST and closes at 2:30am IST.
Both windows cover the same 6.5-hour regular session. The only thing that changes is where that session lands on an Indian clock, and that comes down to daylight saving on the US side, not anything happening in India.
What is a stock exchange?
How exchanges work, what they list, and why they set official open and close times.
Why do US market hours shift twice a year in IST?
Why do US market hours shift twice a year in IST, even though India's clock never changes?
India does not observe daylight saving. IST has stayed at UTC+5:30 since 1947, with no seasonal adjustment.
The US does observe it, moving its clocks forward in spring and back in autumn, and that is the entire reason the IST window moves.
When the US is on daylight time (EDT), it is 9.5 hours behind IST. When the US switches back to standard time (EST), it falls an hour further behind, to 10.5 hours. Since the market's opening bell is fixed at 9:30am on the US side, an extra hour of separation pushes the IST open from 7:00pm to 8:00pm.
Pre-market and after-hours trading in IST
What are pre-market and after-hours trading, and what time is that in IST?
Outside the 9:30am to 4:00pm ET regular session, US exchanges also run pre-market and after-hours windows with thinner volume and wider spreads.
This article is about the IST conversion and the DST shift, not the mechanics of those extended sessions, order types, or the risks that come with trading in them.
For the full breakdown of how pre-market and after-hours trading actually works, including why brokers often restrict them to limit orders, see the pre-market trading guide. The same daylight-saving shift described above applies to those extended windows too: they simply move an hour earlier or later on the IST clock along with the regular session.
What 24/7 market access changes
What does 24/7 market access change for someone trading US hours from India?
Once you know the IST window, the practical question is what round-the-clock access actually changes.
On Cronos app, tokenized stocks trade 24/7 rather than only during the hours listed above, so a US-listed name is not locked to a session that happens to fall late at night in India.
That does not make any particular hour a better time to place a trade. It means the option to check a position or place an order is not limited to a narrow evening window, which matters if the regular US session runs while most of India is asleep.

FAQ
What time does the US stock market open in India?
7:00pm IST when the US is on daylight time (roughly mid-March to early November) and 8:00pm IST when the US is on standard time. The regular session runs 6.5 hours either way, closing at 1:30am or 2:30am IST.
Does the US market time change with Indian daylight saving?
No. India does not observe daylight saving, so IST itself never changes. The shift happens because the US moves its own clocks twice a year, which changes how far ahead IST is of US Eastern time.
What time is pre-market and after-hours trading for US stocks in IST?
Pre-market and after-hours sessions shift by the same hour that the regular session does when the US changes clocks. For the specific US session times and how those sessions work, see the pre-market trading guide linked above.
Can I trade US stocks from India in the middle of the night?
The regular US session falls late at night or into the early morning in IST, so yes, that is when it runs. Whether trading at that hour suits you is a personal call, not something this guide recommends either way.
