Anyone coordinating work across borders eventually needs a reliable picture of Indian business hours, and the answer is less uniform than a single national time zone might suggest. India runs on one clock, Indian Standard Time at UTC+5:30, but it does not run on one schedule. Office hours differ between sectors, the length of the working week differs between industries, and the holiday calendar varies from one state to the next in ways that surprise most foreign teams the first time a Bengaluru office answers and a Kolkata one does not.

This guide sets out the typical office day, the banking and stock market timetable, the truth about the six-day week, and the holidays worth marking in your own calendar. Treat it as a working model of Indian business hours rather than a rule. Everything is given in IST, which you can read live on the IST clock.

What Are Typical Indian Business Hours?

Typical Indian business hours run from 09:30 or 10:00 in the morning to 18:00 or 18:30 IST, Monday to Friday, with a lunch break of about an hour around 13:00. Central government offices generally open at 09:00 or 09:30 and close by 17:30 or 18:00.

Those figures describe the white-collar norm in the major metros. In practice Indian business hours often run longer than the stated ones. IT services and product engineering firms in Bengaluru, Hyderabad, Pune and Noida commonly expect people to stay until 19:00 or later, and a late call with a foreign client is treated as ordinary rather than exceptional. Business process outsourcing is a different world again, running rotating night shifts specifically to cover American and European daytime, so a support line answering at 03:00 IST is entirely normal even though the client-facing project team behind it is not awake.

Banking and Market Hours

Bank branches typically serve customers from 10:00 to 16:00 IST on weekdays, with shorter Saturday hours where they open at all. Equity trading on the National Stock Exchange and the Bombay Stock Exchange runs from 09:15 to 15:30 IST, Monday to Friday, with a pre-open session beforehand. Because India sits ahead of Europe and well ahead of the Americas, the Indian market closes before London reaches midday and long before New York opens.

Indian Business Hours and the Six-Day Week

India is split on the length of the working week. Central government offices, most large corporates, IT services and business process outsourcing work five days, Monday to Friday. Retail, manufacturing, logistics, construction and a great many smaller firms work six, with Sunday as the common day of rest.

Banks sit between the two. Indian banks close every Sunday and on the second and fourth Saturday of each month, which means the first and third Saturdays are ordinary working days for them. That alternating pattern catches out foreign counterparts who assume a fixed weekend, and it is worth checking against the specific month before promising a payment date.

The practical rule when dealing with an unfamiliar Indian organisation is to ask about its working hours rather than assume them. A single company may run a five-day week at its head office and a six-day week at a plant a hundred kilometres away, and both are entirely normal.

Which Holidays Close Indian Offices?

India has only three holidays observed nationwide without exception: Republic Day on 26 January, Independence Day on 15 August and Gandhi Jayanti on 2 October. Everything else, including Diwali, is decided regionally or by the employer, and most dates move each year.

Beyond those three, a second tier is widely observed across most of the country:

  • Diwali: the festival of lights, falling in October or November on a lunisolar reckoning. In the north and west it can close offices for several consecutive days, and it is the single largest planning risk in the Indian year.
  • Holi: the spring festival of colour, falling in March, usually one or two days.
  • Dussehra: ten days before Diwali by the traditional count, and a major holiday in much of the north.
  • Eid al-Fitr and Eid al-Adha: set by the lunar Islamic calendar, so they move roughly eleven days earlier each year.
  • Christmas Day and Good Friday: both are public holidays in India, and Christmas is a substantial one in Kerala, Goa and the Northeast.

Regional Variation Is the Hard Part

The third tier is genuinely local, and this is where cross-border plans usually come unstuck. Durga Puja closes much of West Bengal for four or five days each autumn. Ganesh Chaturthi is a major holiday in Maharashtra and barely marked elsewhere. Onam empties offices in Kerala, Pongal does the same in Tamil Nadu, Ugadi and Gudi Padwa mark the new year in the Deccan and Maharashtra, Baisakhi is central in Punjab and Bihu in Assam. A company with offices in four cities will therefore have four different holiday lists, and the Government of India's own calendar adds a set of restricted holidays from which individual employees choose two or three of their own.

How Do You Plan Around All This?

Ask each partner organisation for its published holiday calendar in December or January, for the year ahead, per office. That single request removes most of the uncertainty, because Indian employers publish these lists formally and treat them as fixed once issued.

Three further habits help. Avoid launching anything in the last week of March, because the Indian financial year ends on 31 March and finance, audit and compliance teams are fully committed. Treat the Diwali fortnight as unavailable rather than merely busy. And when a deadline sits near a movable festival, confirm the date rather than working from last year's, since Diwali can fall anywhere from mid-October to mid-November.

Fitting Indian Business Hours to Yours

Whether Indian business hours are convenient depends entirely on where you are sitting. Against the Gulf the fit is almost perfect: Dubai is only 1 hour 30 minutes behind India and Riyadh 2 hours 30 minutes, with no daylight saving anywhere in the region, so the two working days overlap almost completely. Note that the weekend differs, with Saudi Arabia, Qatar and Kuwait resting on Friday and Saturday. Both sides can be compared on the India and Gulf time page.

Against the United Kingdom the overlap is comfortable, covering an Indian afternoon and a British morning. Against the United States it is narrow and sits at the edges of both days, which is why the calling windows in the best time to call India from the US matter so much, and why the practices in scheduling with India are worth adopting deliberately. The clocks for both countries sit side by side on the India and USA time page.

Conclusion

Indian business hours are typically 09:30 to 18:30 IST on a five-day week for offices and government, a six-day week across much of retail and manufacturing, and 10:00 to 16:00 for bank branches with alternate Saturdays closed. Only three holidays are truly national; everything else, Diwali included, is regional and movable, so the published holiday calendar of the specific office is the document that matters. Get that list early, avoid the Diwali fortnight and the end of March, and the rest is straightforward. Check the current time on the live IST clock or work through any conversion on indiatime.now.
