Why today matters

Today is 21 May BE 2569. Thailand is the only country in the world that uses the Buddhist Era as its primary civil calendar — appearing on every Thai passport, ID card, birth certificate, newspaper headline, school certificate, and lottery ticket. While the Gregorian (Christian Era / คริสต์ศักราช, ค.ศ.) calendar is used in business with international partners, the Buddhist Era (พุทธศักราช, พ.ศ.) is the legal and cultural default for daily Thai life.

ปีพุทธศักราช — "the year of the Buddha's era" — counts Thailand's years from the Buddha's parinibbāna.

How we compute this

Thai Buddhist Era (Suriyakati) is a solar (gregorian-aligned) calendar. Each year contains 365 or 366 days — same as Gregorian, with each month averaging Same as Gregorian (31, 30, or 28/29 days). Years are counted from 1 January 543 BCE — Thai-specific Buddhist Era baseline (era: BE — พุทธศักราช (Phutthasakkarat)).

Thailand adopted the Buddhist Era as its sole civil calendar in 1912 under King Rama VI (Vajiravudh), as part of a broader modernization that included shifting the new year from April to January in 1941 under Field Marshal Phibun. The Thai BE differs by one year from the BE used in Sri Lanka, Myanmar, Cambodia, and Laos: Thailand counts from 543 BCE (the year of the parinibbāna under the local reckoning), while other Theravāda countries count from 544 BCE. To convert any Gregorian year to Thai BE: simply add 543. So 2026 CE = พ.ศ. 2569.

Used by: ≈70 million in Thailand and Thai diaspora communities. Regions: Thailand (sole official civil calendar for government documents, contracts, news, and education).

Frequently asked

What is the Thai date today?
Today's Thai date is 21 May BE 2569. In Thai notation: 21 May พ.ศ. 2569.
How do I convert a Gregorian year to a Thai year?
Add 543 to the Gregorian year. For example, 2026 CE = พ.ศ. 2569. To go from Thai BE to Gregorian, subtract 543.
Why is the Thai BE different from the Sri Lankan BE?
A one-year offset. Thailand counts the year of the Buddha's parinibbāna (final passing) as year 1 of the Buddhist Era — so 543 BCE = BE 1. Sri Lanka, Myanmar, and other Theravāda countries instead count the year *following* the parinibbāna as year 1 — so for them, 544 BCE = BE 1. This produces a permanent 1-year difference: Thai BE 2569 = Sri Lankan BE 2570.
Is January 1 actually the Thai New Year?
Officially yes — since the 1941 reform under Phibun. But culturally, the traditional Thai New Year is Songkran (สงกรานต์), held on 13–15 April. Songkran is when Thai families gather, water-throwing celebrations fill the streets, and most businesses close. The Songkran water festival is inscribed on UNESCO's list of Intangible Cultural Heritage of Humanity (2023).
What about Thai astrology and the 12-year cycle?
Thailand also uses a Chinese-derived 12-year animal cycle (the same Rat/Ox/Tiger/... sequence as in China), with names in Thai (ปีชวด, ปีฉลู, ปีขาล…). 2026 is the Year of the Horse (ปีมะเมีย, Pi Ma-Mia). This cycle is used for personal birth-year identification but does not replace the BE year on documents.
