BTT — Bhutan Time

How to Convert BTT to Other Time Zones

1. Open the BTT converter page: Go to https://www.xconvert.com/time-converter/btt-time-zone to load the visual comparison grid with Bhutan Time (BTT) already shown at UTC+06:00. This page is useful when you need to line up working hours in Bhutan with teams abroad, such as scheduling a call with a supplier in South Asia or checking whether a support handoff from Thimphu overlaps with Europe or North America.

2. Add comparison cities with the + Add City button: Click + Add City and search for places you actually work with, such as London for development agencies and NGOs, Dubai for trade and logistics, or Singapore for regional finance and technology coordination. Because BTT is 6 hours ahead of UTC, these comparisons quickly show whether a Bhutan morning overlaps with Gulf business hours or whether a late-afternoon slot in Bhutan is better for Europe-based partners.

3. Drag across the grid to select a meeting window: Use the Select button if needed, then drag across the BTT row to highlight a time range in purple, such as 9:00 AM to 11:00 AM BTT. That selection corresponds to 3:00 AM to 5:00 AM in London during standard time, 5:00 AM to 7:00 AM in Dubai, and 11:00 AM to 1:00 PM in Singapore, which makes it clear that a Bhutan morning is usually better for East and Southeast Asia than for Europe.

4. Export and share the result: After selecting the range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially helpful for remote teams, because an ICS file or Google Calendar link lets everyone see the same meeting in their own local time automatically, while Copy to clipboard is useful for sending a confirmed overlap window in Slack or email.

About Bhutan Time (BTT)

BTT stands for Bhutan Time, the standard civil time used in the Kingdom of Bhutan. Its exact offset is UTC+06:00, which means local time in Bhutan is always six hours ahead of Coordinated Universal Time. When it is 12:00 noon UTC, it is 6:00 PM in Bhutan.

Bhutan Time is used nationally across Bhutan, including the capital Thimphu and other major population centers such as Phuntsholing, Paro, Punakha, and Gelephu. Bhutan has a population of roughly 790,000 people, and the country is located in the eastern Himalayas between India and China, so BTT is important for cross-border coordination in government, tourism, hydropower, and regional trade.

Because BTT stays fixed at UTC+06:00 all year, it has a straightforward relationship to other major time standards. It is 30 minutes ahead of India Standard Time (IST, UTC+05:30), 2 hours ahead of Gulf Standard Time (GST, UTC+04:00), and 6 hours ahead of GMT/UTC. That means 9:00 AM in Bhutan is 8:30 AM in New Delhi, 7:00 AM in Dubai, and 3:00 AM in London during winter.

Several other abbreviations also use the same UTC+06:00 offset, including ALMT, BST, F, IOT, KGT, OMST, QYZT, VOST, and YEKST, but they do not all refer to the same region or the same daylight-saving behavior. For accurate scheduling, it is better to compare by city or IANA time zone in the grid rather than relying only on abbreviations, because abbreviations can be ambiguous across countries and seasons.

BTT and Daylight Saving Time

Bhutan Time does not observe Daylight Saving Time. The current DST status for BTT is false, so Bhutan does not switch forward in spring or back in autumn. In 2026, there are no DST transition dates for BTT, and the offset remains UTC+06:00 from January 1, 2026 through December 31, 2026.

This fixed offset makes BTT easier to use for recurring scheduling than time zones that change seasonally. For example, a weekly meeting set for 4:00 PM BTT will always stay at 4:00 PM Bhutan local time, but the corresponding time in places like London, New York, or Berlin may shift when those regions enter or leave daylight saving time.

That seasonal difference matters in real business coordination. A Bhutan-based tourism operator, development organization, or regional operations team may notice that a call with London moves by one hour relative to UK local time between late March and late October, even though Bhutan itself never changes clocks.

Frequently Asked Questions

What does BTT stand for?

BTT stands for Bhutan Time, the national standard time used in Bhutan. It is set at UTC+06:00, so Bhutan is always six hours ahead of Coordinated Universal Time and does not use seasonal clock changes.

Is BTT the same as GMT?

No, BTT is not the same as GMT. GMT is effectively UTC+00:00, while BTT is UTC+06:00, so Bhutan Time is 6 hours ahead of GMT; when it is 9:00 AM GMT, it is 3:00 PM BTT.

Which cities use BTT?

BTT is used across Bhutan, including Thimphu, Phuntsholing, Paro, Punakha, and Gelephu. Since Bhutan uses one national time standard, the same local clock applies throughout the country, which is useful for domestic travel planning, public administration, and nationwide business operations.

What is the UTC offset for BTT?

The UTC offset for BTT is +06:00. This means you add 6 hours to UTC to get Bhutan local time, so 10:00 UTC becomes 4:00 PM BTT on the same calendar day.

When does BTT change?

BTT does not change during the year because Bhutan does not observe daylight saving time. In 2026, there are no spring-forward or fall-back dates, so the offset remains UTC+06:00 every day of the year.

Is BTT the same as India Standard Time?

No, BTT and India Standard Time (IST) are different. IST is UTC+05:30 and BTT is UTC+06:00, so Bhutan is 30 minutes ahead of India; when it is 9:00 AM in Thimphu, it is 8:30 AM in Kolkata or New Delhi.

How far ahead is Bhutan Time from UTC?

Bhutan Time is 6 hours ahead of UTC. A simple way to calculate it is to add six hours to UTC, so 6:00 AM UTC equals 12:00 noon in Bhutan.

Does Bhutan use daylight saving time?

No, Bhutan does not use daylight saving time at all. That means BTT stays consistent for year-round scheduling, which is helpful for recurring meetings, airline planning, hotel operations, and coordination with neighboring South Asian markets.
