NSE Market Hours Converter

Use this NSE market hours converter to translate a time you enter in IST (India Standard Time) into a selected overseas clock time. Check the limitations before relying on it: Pacific Time currently follows the Eastern Time calculation, and daylight-saving changes use a rough month-based rule. The form has no trading-date input. Confirm the destination city and date with a date-aware clock before planning a session.

What the form asks you to enter

• NSE Time (IST): type the Indian clock time you want to translate, using hours and minutes separated by a colon.
• Your Time Zone: choose one of the listed destinations. The dropdown is a fixed list, with the Pacific issue described above.
• Market Session: selects a session category. Changing it does not replace the time in NSE Time (IST).

The displayed Converted Time refers to your entered time. Market Name and Market Hours refer to the destination market stored in the converter. They are not a current NSE opening-and-closing timetable. Offset From I S T is the amount the tool adds to or subtracts from the Indian time.

For example, selecting a pre-market session while leaving a later source time in the box still converts that later time. Read the source time itself before interpreting the result.

Check the NSE segment before converting its hours

As checked on 15 Oct 2026, NSE’s equity-derivatives table lists normal trading from 09:15 to 15:40 IST and trade modification ending at 16:15 IST. Circular NSE/FAOP/74467, dated 29 May 2026, made the revised normal close effective from 3 Aug 2026. A trade-modification deadline is a separate event from the close of normal trading.

The session menu above still shows an older normal close for equity derivatives. Do not treat those labels as an up-to-date timetable for every NSE segment. Cash equities, equity derivatives and currency derivatives have separate session rules. Check the linked exchange page and any dated notice for your instrument.

Use the official NSE segment timings as the starting point. Our trading-day counter covers a different question: which dates are trading days. A correct conversion does not establish that a particular date is open.

NSE trading hours today: timings by segment

NSE does not have one trading day. Each segment has its own sessions, and in 2026 two rule changes took effect on 3 August. The table gives each window in IST. Every row names its source, and where two NSE pages disagree, both are shown. Timings can change by circular, so check the NSE page for the date you are trading.

These sources conflict. NSE's pre-open page and older market-timings page show order entry closing at 09:08 (random closure in the last minute) and matching from 09:08 to 09:12. News reports say NSE revised this from 7 September 2026: all orders from 09:00 to 09:05, limit orders only from 09:05 to 09:10, matching from 09:10 to 09:12. We could not open the NSE circular for the revision, so we cannot say which version applies to you. Confirm the current pre-open timings on nseindia.com before you rely on a second.

NSE opening time and the pre-open session

For most people, the market opens at 09:15 IST. The 15 minutes before that are the pre-open session for the cash market, where orders are collected and a single opening price is found. It has four steps: an order entry period with all order types, an order entry period with limit orders only, a matching period and a buffer. During the buffer you cannot enter orders, which is why many traders treat 09:15 as the first moment of live trading. Equity derivatives follow their own opening at 09:15.

Worked example: an entered IST time to Singapore

Suppose, as an illustrative clock example, you enter 10:00 in NSE Time (IST) and choose Singapore Time (SGT). This source time is chosen for checking the arithmetic, rather than presented as an exchange opening. CSIR-NPL defines IST as UTC plus 5:30 hours; Microsoft’s time-zone documentation lists Singapore at UTC plus 8 hours.

• The example source time is 600 minutes after midnight.
• Singapore’s offset exceeds the Indian offset by 8 − 5.5 = 2.5 hours, or 150 minutes.
• Add the difference: 600 + 150 = 750 minutes after midnight.
• That gives 12:30 in Singapore, displayed as 12:30 PM.

The existing calculation returns 12:30 PM for that example. The GMT choice needs a separate warning: it currently maps to a UK market entry that applies a seasonal adjustment, so it does not reliably give fixed GMT. Use a date-aware city clock when planning UK sessions.

NSE closing time and the closing auction session

Two changes took effect on 3 August 2026. Equity derivatives now close their normal market at 15:40, as shown above. For the cash market, NSE brought in a closing auction session (CAS), a short session that sets the closing price. NSE circular NSE/CMTR/75479 is cited for the equity-segment changes going live on 3 August 2026. Sources give different circular dates (30 July 2026 on our reading of the circular reference, 29 May 2026 in some news reports), so confirm the circular and its date on nseindia.com.

NSE's CAS page describes the session as running from 15:15 to 15:35, with these steps. Parts of this table come from search quotes of that page, since the circular itself would not open for us.

CAS applies at first to cash-market stocks that have listed F&O contracts. Other stocks keep the older method, a volume-weighted average of late trades. Lessons for traders: do not use one universal close for the whole market, and do not assume a cash stock, a CAS stock and an F&O contract all stop at the same minute. The older NSE page also lists a post-close closing session at 15:40 to 16:00 for the cash market; check which applies to your stock. These timings conflict: the older page's cash close of 15:30 and post-close session of 15:40 to 16:00 do not match the CAS page's 15:15 to 15:35 auction and 15:35 to 15:50 transition. Treat each as unconfirmed until you check nseindia.com for the current timetable.

Pacific Time, GMT and daylight saving need a separate check

The Eastern and Pacific choices currently point to the same destination-market calculation. The Pacific result therefore cannot be used as a dependable US West Coast clock. The regions have different local times; this form maps them incorrectly.

The calculator also guesses daylight-saving status from the current month. Real changes occur on specific dates, and the relevant dates differ between regions. NIST describes US changes on particular Sundays; a month-only approximation cannot reproduce those boundaries. There is no date field here to calculate a past or future session’s offset.

Around a clock change, confirm both the Indian date and the destination’s local date. When conversion crosses midnight, the day can change too. This form prints a clock time without a reliable accompanying destination date. For example, midnight entered as 00:00 is also mishandled: the calculation substitutes a stored morning time. Check that conversion elsewhere.

NSE timings in GMT, UK, Singapore, Dubai and US time

India Standard Time is UTC plus 5:30 all year, since India does not use daylight saving. To convert, subtract 5 hours 30 minutes to get UTC (which is the same as GMT), then add the other place's offset. The table shows four IST moments. UK time is GMT now because UK clocks went back on 25 October 2026. US Eastern is still on daylight time until 1 November 2026, and then moves one hour back. Singapore (UTC plus 8) and Dubai (UTC plus 4) have no daylight saving.

The converter tool above handles Singapore, but its Pacific and GMT choices have faults, as described earlier, so use this table or a date-aware city clock for those. In the US, the Eastern times above move back by one hour on the same clock moments after the change, which is why the table has two columns.

Is NSE open on weekends and holidays?

NSE's normal trading days are Monday to Friday. Saturdays and Sundays are closed unless NSE announces a special session by circular. Public holidays are also closed. The 2026 holiday dates in our project's calendar that remain after today are 10 November, 24 November and 25 December. Verify them on NSE's holiday page, because a holiday list can be revised.

Special sessions exist too. Muhurat trading on Diwali is a short evening session whose date and time NSE announces each year, and the exchange can also announce a special live session on a weekend. Do not assume a normal day's hours apply to these. If a holiday falls on an expiry day, the expiry moves to the previous trading day, as our expiry day calculator and expiry rules reflect.

NSE vs BSE timings

BSE and NSE usually run similar hours for equities and derivatives, but each exchange issues its own circulars, and a change can take effect on different dates. Read BSE's own notice for BSE-listed contracts such as Sensex options, and NSE's for NSE contracts. Do not copy one exchange's timetable to the other.

A short checklist for overseas planning

• Identify the exchange segment and the event: opening, normal close, auction or a broker’s own deadline.
• Copy the current official IST time into the source field yourself.
• Check the intended destination city and trading date separately.
• Confirm holidays and special sessions with the exchange.
• Keep the time zone beside any time you record in a trading note.

For broader comparisons, see the global market-hours mapper. For expiry planning, the expiry-day calculator addresses dates rather than time-zone conversion. Review their stated limits before combining results.
