What the song is about
7 วัน 7 สีjèt wan jèt sǐi, “7 Wan 7 Si (Seven Days, Seven Colours)”, is a Thai children's song by MomKids. A sing-along that teaches Thai children the seven days of the week and the colour Thailand gives each one, from red Sunday to purple Saturday, and then quizzes them. The singing is slow and clear, so it is an easy way to learn the days, a few colours and how to ask what colour something is.

Key lines, explained
Tap a line to hear it. Once the video is playing, lines jump to their moment in the song.
- สัปดาห์ sàp-daaหนึ่ง nùengมี miiเจ็ด jètวัน wan
A week has seven days.
สัปดาห์sàp-daa = week, the word you'll see in writing; in conversation Thais more often say อาทิตย์aa-tít. A noun + หนึ่งnùeng (one) means 'a, one': สัปดาห์หนึ่งsàp-daa nùeng = a week, in a week, and วันหนึ่งwan nùeng = one day. มีmii = to have, there are. (The video's subtitles write หนึ่งสัปดาห์นั้นnùeng sàp-daa nán, but she sings it this way.) She goes on to say it the other way round. - วันอาทิตย์ wan-aa-títสี sǐiแดง daeng
Sunday is red.
วันอาทิตย์wan-aa-tít = Sunday, the day of the sun (อาทิตย์aa-tít). สีsǐi = colour, and a colour word follows it: สีแดงsǐi daeng = red, the colour red. Thai needs no 'is' here: วันอาทิตย์สีแดงwan-aa-tít sǐi daeng, 'Sunday, colour red'. - วันจันทร์ wan-janสี sǐiเหลือง lǔeangช่างสดใส châang sòt-sǎi
Monday is yellow, so bright.
วันจันทร์wan-jan = Monday, the moon's day. เหลืองlǔeang = yellow, with a rising tone. ช่างchâang before a describing word means 'so, how…!', a little poetic: ช่างสดใสchâang sòt-sǎi = so bright and cheerful (สดใสsòt-sǎi = bright, fresh). Careful: on its own, ช่างchâang is a mechanic or a craftsman. - ก็ gâwครบ krópเจ็ด jètวัน wanเจ็ด jètสี sǐi
And that makes all seven days, seven colours.
ครบkróp = complete, all there: ครบเจ็ดวันkróp jèt wan = the full seven days. You'll hear it all the time: ครบไหมkróp mǎi = is everyone (everything) here? ก็gâw at the start = and so, so then. It's also the song's title: เจ็ดวันเจ็ดสีjèt wan jèt sǐi. - วันอาทิตย์ wan-aa-títสี sǐiอะไร à-raiคะ ká
What colour is Sunday?
Now the quiz: the singer asks and the children answer. สีอะไรsǐi à-rai = what colour?, with the question word at the end, where the answer goes: วันอาทิตย์สีอะไรwan-aa-tít sǐi à-rai → สีแดงsǐi daeng. Ask it about anything: รถสีอะไรrót sǐi à-rai = what colour is the car? She ends her question with คะká, high, the polite particle a woman puts after a question; after a statement she says ค่ะkâ, falling, as in the Thursday line. - วันพฤหัสบดี wan-pá-rúe-hàt-sà-baw-diiค่ะ kâสี sǐiส้ม sôm
Thursday. Orange!
The teacher calls out the day, politely, with ค่ะkâ, and the children answer with its colour. วันพฤหัสบดีwan-pá-rúe-hàt-sà-baw-dii is Thursday's full name, the day of Jupiter; in everyday speech everyone says วันพฤหัสwan-pá-rúe-hàt. ส้มsôm = orange, the fruit and the colour.

The culture behind it
Why every Thai day has a colour. The colours come from Hindu astrology: each day belongs to a planet and its god, with his own colour, which is why Monday, the moon's day, is yellow and Sunday, the sun's, is red. Many Thais know the colour of the day they were born on, and some still wear the colour of the day. The song runs through all seven, starting from Sunday, then goes over them again as a question-and-answer quiz. Our page on colours in Thai has many more colour words.
MomKids is a Thai channel of learning songs for small children, and the song's credit at the start of the video names Sombat Kajonchaikul as its creator (สร้างสรรค์sâang-sǎn, 'created by'). The video went up in October 2015, and its subtitles come in twenty languages; the song itself is older, as a blog of children's songs had its words in March 2012.
