About English and Thai
English (English) is written in the Latin script and spoken by about 1.5 billion, mainly in the UK, the US, Canada, Australia, Ireland, India and most international organisations. US documents write dates month-first (04/10/2026 is April 10) while British and most other documents write them day-first, so check dates carefully when moving between regions.
Thai (ไทย) is written in the Thai script and spoken by about 60 million, mainly in Thailand. Thai writes no spaces between words, and official Thai documents date years in the Buddhist Era, 543 years ahead of the Gregorian calendar (2026 is B.E. 2569).
