Global Market Hours Mapper: Sessions in IST

Global stock-market hours depend on the date, exchange and session. The table below compares selected New York, London, Tokyo and NSE sessions in Indian Standard Time (IST), including seasonal clock settings and closes on the next Indian date. The mapper itself shows fixed cards: it cannot check holidays, early closes or clock changes. Its US premarket card is not a universal opening time. Confirm the exchange calendar for the intended trading day.

What the controls actually change

Select Region offers Americas, Europe, Asia-Pacific, Middle East and All Major Exchanges. In the current tool, that selection mainly changes the Best Time For Style wording. It does not produce a separate exchange-by-exchange table for every country listed in the menu.

Show NSE Overlap hides or reveals the Europe Overlap card. That card uses the same stored window across region selections. Us Premarket Start and Pre Market Watch are also fixed text. The form has no trading date, exchange holiday, local-time input or time-zone selector.

Treat Best Time For Style as an unsupported preset, not a measured opportunity or a recommendation. An exchange opening time does not establish predictable volatility, a correlation with another market or the direction of its next price move.

Global market timings in IST: quick table

Indian Standard Time (IST) is UTC +05:30 and does not change with the seasons. The table converts regular sessions on a normal full trading day. Subtract the exchange's UTC offset from IST to see the gap: Hong Kong and Shanghai are UTC +08:00, so their clocks run 2 hours 30 minutes ahead of India.

Hong Kong has an extended morning session between 12:00 and 13:00 on full days, so there is no lunch break there. HKEX also states there is no extended morning or afternoon session on the eves of Christmas, New Year and Lunar New Year. Shanghai's continuous trading runs until 14:57, followed by a closing call auction to 15:00, which is 12:27 to 12:30 in India. Tokyo and Shanghai keep a lunch break.

Selected regular sessions, converted to India time

The table below is a reference comparison for normal full trading days, checked 16 October 2026. The selected session matters: NYSE core equities, London Main Market, Tokyo domestic stocks and NSE equity derivatives are different services. Opening auctions, order acceptance and extended sessions need separate checks.

NYSE’s hours page distinguishes core sessions and earlier sessions across its different venues. Its core equity session is not the same thing as a broker’s available premarket window. A single card labelled US premarket cannot describe every venue or product.

LSEG’s announcement keeps the London Main Market’s existing hours separate from its planned new venue. Do not substitute a future extended-hours proposal for the Main Market timetable.

Japan Exchange Group lists separate morning and afternoon sessions. The lunch interval is not continuous domestic-stock trading. For the Indian session, use NSE’s current segment-specific timings; a cash-market timetable cannot automatically stand in for equity derivatives.

Clock changes fall on different dates

UTC is the global reference clock. Indian Standard Time is UTC +05:30, as maintained by CSIR-NPL. The conversion changes when the foreign location changes its clocks, even when the exchange keeps the same local opening time.

GOV.UK lists the autumn change on 25 October 2026. NIST lists the US daylight-saving end on 1 November 2026. The London and New York conversions therefore change on different dates. Confirm which rule applies to the exchange’s local trading date.

Eastern Time is a regional clock label that can mean daylight or standard time. Eastern Standard Time is specifically UTC −5, while Eastern Daylight Time is UTC −4. Keeping the word EST on a year-round schedule can cause an incorrect India-time conversion.

Daylight saving dates in 2026 and the weeks in between

The UK clocks went back on Sunday 25 October 2026, so London is now on Greenwich Mean Time. NIST states US daylight saving time runs from 8 March to 1 November 2026. Between 25 October and 1 November, London is on standard time while New York is still on daylight time. In that week, London trades 13:30-22:00 IST and New York trades 19:00-01:30 IST.

The same gap appears in spring. US clocks moved forward on 8 March 2026 and UK clocks on 29 March 2026, so for those weeks New York was on daylight time while London was still on standard time. Always read the date, not the season. Japan, Hong Kong, China and India do not change their clocks, so their IST times stay fixed all year.

Worked conversion: New York’s core opening

For a normal full session while New York uses daylight time, its 09:30 opening is UTC −4. India is UTC +05:30. The difference is 9 hours 30 minutes, so 09:30 plus that interval becomes 19:00 IST. The 16:00 close becomes 01:30 IST on the following calendar day.

Use the worked conversion to check official local hours against Indian time. The mapper’s fixed US premarket card does not perform that conversion or change with the season.

US market hours in India, including extended sessions

NYSE's core session runs 09:30 to 16:00 Eastern. Outside it, the exchange group lists early and late sessions that differ by market. NYSE Arca's early session starts at 04:00 Eastern. For several other NYSE markets the early session starts at 07:00. Late sessions run 16:00 to 20:00 Eastern. Your broker may offer only some of these, so check what your broker accepts.

NYSE lists two early closes in 2026: Friday 27 November and Thursday 24 December, both at 13:00 Eastern. It also lists Thanksgiving on 26 November and Christmas on 25 December as holidays.

An overlap means simultaneous open sessions

For the London Main Market and NSE equity derivatives shown above, the normal-session overlap is 12:30–15:40 IST during British Summer Time and 13:30–15:40 during Greenwich Mean Time. A holiday in either market removes that ordinary-day comparison.

NYSE’s regular core equity session opens after the stated NSE equity-derivatives session closes. They do not overlap on a normal full day under either US clock setting. US futures, an early equity session and a later regular stock session are different comparisons; name the exact product before calculating overlap.

Tokyo’s domestic-stock afternoon overlaps the start of the stated Indian session, while Tokyo’s morning has already ended. Do not draw an uninterrupted Asia window across the Japanese lunch break or treat a regional label as a common holiday calendar.

Which markets are open during Indian trading hours

Using the table above, these are the overlaps with the NSE equity derivatives session of 09:15 to 15:40 on a normal day.

• Tokyo: the afternoon session (09:00-12:00 IST) overlaps the first part of the Indian morning.
• Hong Kong: the session runs from 07:00 to 13:30 IST, so it overlaps from 09:15 until 13:30 IST.
• Shanghai: the afternoon continuous session ends 12:27 IST and its lunch break covers 09:00 to 10:30 IST, so the overlap with the NSE session runs from 10:30 to 12:30 IST including its closing auction.
• London: 13:30 to 15:40 IST in the winter months, or 12:30 to 15:40 IST in summer.
• New York: the core session does not overlap the NSE session. NYSE Arca's early session (13:30-19:00 IST in daylight time, 14:30-20:00 IST in standard time) overlaps the last part of the Indian session, until 15:40 IST.

An overlap says two markets are open together. It says nothing about direction, volume or the quality of trading in either one.

GIFT Nifty session timings

GIFT Nifty trades on NSE International Exchange in GIFT City. NSE says its contracts are accessible for almost 21 hours a day, which overlaps Asian, European and US hours. Traders watch it before the NSE open because it trades while Indian cash markets are shut.

Websites disagree on the exact session times. Some give a first session from 06:30 to 15:40 IST and a second from 16:35 to 02:45 IST. One broker-fund page that cites an NSE IX circular dated 1 September 2026 gives 05:15 to 15:40 IST and 16:05 to 02:45 IST from 12 October 2026. We could not open the circular, so none of these times is confirmed. Check the current NSE IX circular on trading hours before you rely on a time. Exchange holidays and special sessions can change it.

Keep date and session beside the observation

• Choose the exchange and product before choosing a region label.
• Check the exchange’s own calendar for its local date, including holidays or an early close.
• Identify regular trading, auction, order-entry and extended sessions separately.
• Apply the correct seasonal clock offset and keep any next-day marker.
• Compare the converted interval with the exact Indian segment you mean.
• Record the actual observation time separately from the exchange schedule.
