The Thai calendar

What are the days of the week in Thai?

The days of the week in Thai are wan-aa-tít (Sunday), wan-jan (Monday), wan-ang-kaan (Tuesday), wan-pút (Wednesday), wan-pá-rúe-hàt-sà-bor-dii (Thursday), wan-sùk (Friday) and wan-sǎo (Saturday): wan, "day", followed by the day's name.

In casual speech the wan is often dropped, and Thursday is shortened to pá-rúe-hàt. A Thai calendar starts the week on Sunday, and a calendar or a timetable writes each day in its short form.

What are the months in Thai?

The months in Thai are twelve names whose endings give their length: -kom for the months with 31 days, -yon for the months with 30, and -pan for February.

So you can tell September, gan-yaa-yon, has 30 days just by its name. In speech the ending is often dropped: mii-naa for March, mee-sǎa for April. Written in short, each month is two or three letters with periods, as in the table.

What year is it in Thailand?

It is 2569 in Thailand during 2026, and 2570 during 2027, because Thailand counts years in the Buddhist Era, which runs 543 years ahead of the Common Era.

To find the Thai year, add 543 to the Western year. The Buddhist Era is written with the abbreviation พ.ศ.por-sǒrbefore the year on documents, receipts and newspapers, and the year is said as one whole number, sǒrng-pan-hâa-rói-hòk-sìp-gâo for 2569. The Thai year starts on January 1, like the Western one. You will see Western years too, on flights and international sites.

How do you write and say the date in Thai?

You write and say the date in Thai as wan-tîi, then the day's number, then the month, then the Buddhist Era year, so April 13, 2026 is wan-tîi sìp-sǎam mee-sǎa-yon sǒrng-pan-hâa-rói-hòk-sìp-gâo.

Put the day of the week in front to say it in full. Most dates are written with the same digits as English, and some official documents use Thai digits. Pick a date in the converter below to see it written, hear it said word by word, and find its color, season and any holiday.

What are the seasons in Thailand?

Thailand has three seasons: the hot season from mid-February to mid-May, the rainy season from mid-May to mid-October, and the cool season from mid-October to mid-February.

Those are the Thai Meteorological Department's dates. The Thai names use the words for summer and winter, but the cool season is only cool by Thai standards, mostly in the north. Spring and autumn are words for seasons elsewhere.

What color is each day in Thailand?

Each day in Thailand has its own color: red for Sunday, yellow for Monday, pink for Tuesday, green for Wednesday, orange for Thursday, light blue for Friday and purple for Saturday.

The colors come from astrology, and many Thais know the color of the day they were born on. You will see a lot of yellow on Mondays, the day King Bhumibol and King Vajiralongkorn were both born on. The color of the day is สีประจำวันsǐi bprà-jam wan.

How can you learn the Thai days and months fast?

You can learn the Thai days and months fast by learning their patterns first, saying today's date out loud every morning and listening as you go, which is what Mooteach's calendar reference is for, with every day and month in a male and a female voice.

Start with the days, since each is wan and one more word, then learn the months by their endings, which tell you their length. Say the whole date with the year, and the numbers get practice too.

Is there an app for learning the Thai calendar?

Yes, there is an app for learning the Thai calendar: Mooteach, whose calendar reference teaches the days, the months, the Buddhist Era year and how to say a date, with audio for every word.
