Current Time in Guwahati, India
How to Check Current Time in Guwahati, India
Open the Guwahati time converter page: Go to https://www.xconvert.com/time-converter/india/guwahati to load Guwahati pre-selected on the comparison grid in the India time zone. This is useful if you are planning a call with a client in Assam, checking a train or flight timing through Northeast India, or coordinating with a remote team that works on India Standard Time.
Add comparison cities with the “+ Add City” button: Click + Add City and search for cities such as London, New York, or Dubai to compare Guwahati against major business and travel hubs. These are practical choices because UK and US teams often work with Indian IT, consulting, and support operations, while Dubai is a common trade and aviation connection point for Indian business travelers.
Drag across the grid to select a meeting window: Use the Select button if needed, then drag on Guwahati’s 24-hour timeline to highlight a time range in purple, such as 9:00 AM to 11:00 AM IST. On the same grid, you will immediately see that this corresponds to 3:30 AM to 5:30 AM in London during standard time, or 4:30 AM to 6:30 AM when the UK is on British Summer Time, which helps confirm that a Guwahati morning slot is usually too early for Europe.
Export or share the selected time range: After selecting a range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially helpful when sending a confirmed meeting slot to a distributed team, because the calendar export lets everyone see the event in their own local time automatically without manually converting Guwahati time.
About Guwahati Time Zone
Guwahati uses the IANA time zone Asia/Kolkata, which is the standard time zone for all of India. Its UTC offset is UTC+05:30, meaning Guwahati is 5 hours and 30 minutes ahead of Coordinated Universal Time throughout the year. India does not use multiple official civil time zones, so Guwahati follows the same clock as Delhi, Mumbai, Bengaluru, Kolkata, and Chennai despite being far to the east.
Guwahati is the largest city in Assam and a major gateway to Northeast India, but it does not have a separate regional time standard. Although sunrise and sunset occur earlier in Assam than in western India because of longitude, official time remains India Standard Time under Asia/Kolkata. This matters for practical scheduling: local daylight in Guwahati starts earlier than in cities like Mumbai, even though both display the same clock time.
Guwahati does not observe daylight saving time. The offset stays at UTC+05:30 in January, June, and every other month, so there are no seasonal clock changes to track locally. Compared with neighboring countries, Guwahati is 30 minutes behind Bangladesh Standard Time (UTC+06:00) and 1 hour 30 minutes behind Thailand (UTC+07:00), while being 15 minutes ahead of Nepal Time (UTC+05:45).
Guwahati City Details
Guwahati is a major urban center in northeastern India with a population of 899,094. It serves as a commercial, educational, transport, and administrative hub for Assam and the wider Northeast region, making it a common reference point for domestic business coordination, university schedules, logistics planning, and regional travel.
The city is located at 26.1844° N, 91.7458° E, on the southern bank of the Brahmaputra River. These coordinates place Guwahati well east of India’s political and financial capitals, which helps explain why daylight begins relatively early compared with western Indian cities even though the official time zone remains the same.
Guwahati uses the Indian rupee (INR) for all local transactions, including hotels, taxis, retail purchases, and business payments. The country dialing code is +91, so international callers would dial India first and then the relevant local or mobile number when contacting businesses, hotels, universities, or residents in Guwahati.
Time Differences from Guwahati
Guwahati is 10 hours 30 minutes ahead of New York during Eastern Standard Time (UTC-05:00) and 9 hours 30 minutes ahead during Eastern Daylight Time (UTC-04:00). For example, when it is 9:00 AM in Guwahati, it is 10:30 PM the previous day in New York during EST, or 11:30 PM the previous day during EDT. This large gap means Guwahati morning hours usually align only with late evening in the US East Coast.
Guwahati is 5 hours 30 minutes ahead of London during Greenwich Mean Time (UTC+00:00) and 4 hours 30 minutes ahead during British Summer Time (UTC+01:00). When it is 9:00 AM in Guwahati, it is 3:30 AM in London during winter and 4:30 AM in summer. For UK-India coordination, late afternoon in Guwahati often works better than Guwahati morning.
Guwahati is 3 hours 30 minutes behind Tokyo, because Japan Standard Time is UTC+09:00 year-round. When it is 9:00 AM in Guwahati, it is 12:30 PM in Tokyo. This makes Guwahati mornings and Tokyo lunchtime overlap well for manufacturing, electronics, shipping, and regional Asia-Pacific business communication.
Guwahati is 4 hours 30 minutes behind Sydney when Sydney is on Australian Eastern Standard Time (UTC+10:00) and 5 hours 30 minutes behind when Sydney is on Australian Eastern Daylight Time (UTC+11:00). So 9:00 AM in Guwahati is 1:30 PM in Sydney during AEST or 2:30 PM during AEDT. This is useful for education, travel, and corporate scheduling between India and Australia, especially because the offset changes seasonally on the Australian side, not the Indian side.
Guwahati is 1 hour 30 minutes ahead of Dubai, since Gulf Standard Time is UTC+04:00 year-round. When it is 9:00 AM in Guwahati, it is 7:30 AM in Dubai. This is a practical overlap for aviation, trade, recruitment, and family communication, because both locations avoid daylight saving time and keep a stable difference all year.

From the US, especially the East Coast, many live calls require either US late evening or Guwahati early morning, because the gap is 9.5 to 10.5 hours; for smoother coordination, teams often use shared slots around 6:00 PM to 8:00 PM Guwahati time.

What currency does Guwahati use?
