What Year Is It in Thailand? Everything You Need to Know About the Thai Buddhist Calendar
12 Dec. 2025
Traveling to Thailand means stepping into a country where time flows differently than elsewhere. In the bustling streets of Bangkok, in the temples of the North, or between the islands of the South, visitors often encounter dates that seem puzzling: 2567, 2568, 2569… Numbers that appear to come from the future. Yet this is no error, but rather the Buddhist calendar, one of the Kingdom's most profound cultural anchors.
But then, why doesn't Thailand use the same year as we do? What is the current year in Thailand? Discover everything you need to know about the Thai calendar...
Which Calendar Does Thailand Use?
Thailand uses the Buddhist calendar (or Buddhist Era, abbreviated BE) as its official calendar. It's a dating system founded on the life of Buddha.
What Is the Buddhist Calendar?
The Buddhist calendar, used in Thailand, originates from a founding event: the passing of Gautama Buddha, which occurred in 543 BCE according to tradition. This date marks the beginning of the Buddhist Era, used to count years in Thailand. Where our Gregorian calendar counts years from the birth of Christ, the Buddhist calendar thus honors the spiritual heritage and teachings of Buddha.
The year 1 of the Buddhist calendar therefore corresponds to the year 543 BCE. It's worth noting that while there's a 543-year gap between the Buddhist and Gregorian calendars, the months and days follow a similar structure in both systems.

Since When Has Thailand Used the Buddhist Calendar?
The use of the Buddhist calendar in Thailand dates back several centuries, but its official adoption solidified during the reign of King Rama V (late 19th – early 20th century). At that time, the sovereign undertook to unify the various dating systems in use and establish the Buddhist Era as the national reference, modernizing administration while preserving the country's cultural identity.
Before this reform, the kingdom followed a traditional lunisolar calendar: months began with the new moon, changed length from year to year, and an extra month was occasionally added to stay in phase with the seasons. A system rich in symbolism, but complex to manage daily.
In 1940, a new milestone marked the transition toward a more modern organization: the government adopted the same months as the Gregorian calendar, while preserving the Buddhist year calculation. From this fusion was born the Thai calendar as we know it today, a singular balance between spiritual tradition and modern practicality.

What Year Is It in Thailand?
The Buddhist year is calculated by adding 543 years to the Western year. In 2025, Thailand is officially in 2568 BE (BE for "Buddhist Era"). For the year 2026, we will be in 2569 BE.
How to Convert a Thai Calendar Year to a Western Year?
Wondering how to convert a Thai calendar year to a Western year? Here's how to calculate which year Thailand is in:
🧮
Conversion Formula
Thai year = Gregorian year + 543
Gregorian year = Thai year – 543
Moreover, to find out which year Thailand is in, simply add 543 to the current Gregorian calendar year. This difference applies from January 1st of each year, just like in our own calendar. The months and days remain identical to the Western calendar, making the conversion even simpler.
How Is the Buddhist Calendar Used in Daily Life in Thailand?
In Thailand, the Buddhist calendar isn't just a temporal reference: it's everywhere, in daily life and administration alike, and it coexists with the Gregorian calendar for international exchanges and tourism.
The Buddhist Calendar in the Daily Life of Thai People
In schools, temples, and certain local services, dates are still displayed in Buddhist Era (BE). For children, learning that the school year begins in 2568 is as natural as it is for us to write 2025. Religious ceremonies, community events, and even municipal displays follow this system, reminding Thai people daily of their spiritual and cultural heritage.
The Buddhist Calendar in Official Thai Documents
It's especially in administration where the use of the Buddhist Era is most visible. Here are the documents where you'll most often see the Buddhist year:
- receipts in local shops and supermarkets,
- rental service receipts (scooters, cars, etc.),
- contracts and official forms,
- medical documents,
- civil status documents such as birth or marriage certificates,
- Thai passports...
This presence of the Buddhist calendar in administrative life testifies to its deep roots in Thai culture, while coexisting harmoniously with international usage.
The Buddhist Calendar in Tourism and Commerce
In sectors oriented toward tourism and international commerce, the Gregorian calendar remains more frequent nonetheless. Hotels, travel agencies, airlines, and booking platforms predominantly use our calendar as a reference, to facilitate exchanges.
Thus, it's common to see the Gregorian calendar year displayed on airline tickets, hotel or excursion reservations, train or bus tickets... This coexistence of the two systems allows foreigners to orient themselves easily, while preserving local cultural richness.
📅
Is the Buddhist Calendar Used in Other Asian Countries?
The Buddhist calendar exists in several Theravāda Buddhism countries – such as Laos, Cambodia, Myanmar, or Sri Lanka – but its official use varies. Thailand is among the rare countries to continue using it as an administrative reference, while its neighbors employ it mainly for religious festivals and traditional events.
Do You Need to Know the Buddhist Year to Travel to Thailand?
As you've gathered, Thai people juggle two temporal references: on one hand, the Buddhist calendar, very present in the State and traditions, and on the other, the Gregorian calendar, used in international exchanges, tourism, bilingual documents, and communications with abroad.
It's not essential to master the Buddhist calendar to travel to Thailand, but a few basic notions can help you avoid small mix-ups.
To avoid any error and confusion, simply adopt a few simple reflexes:
Always check if the date is expressed in Buddhist year: a date beginning with 25 almost always corresponds to the Buddhist calendar, whereas a standard four-digit year is generally Gregorian.
Observe the context: an official form, a shop receipt, or a local receipt is often in BE, while a flight or hotel reservation will be in the Gregorian calendar.
Apply the quick conversion rule: to go from Buddhist to Gregorian, subtract 543; to go from Gregorian to Buddhist, add 543.
Refer to the abbreviations: "พ.ศ." (Phô Sô) indicates the Buddhist year, and "ค.ศ." (Khô Sô) the Western calendar.
These simple reflexes will allow you to read dates without hesitation and avoid any administrative or logistical error.
Understanding the Buddhist Calendar: A Key to Traveling in Thailand
Understanding which calendar Thailand uses is more than just a practical matter: it's a way to enter the soul of the country. The Buddhist calendar tells the story of a nation shaped by spirituality, faithful to its history while opening itself to the modern world. And if a date seems to come straight from the future, remember: in Thailand, time is counted differently, but the welcome remains timeless...
