Each day’s colour comes from the deity of its planet in Thai astrology. Many Thais wear their birthday colour, or the colour of the day — yellow on Monday, light blue on Friday and so on.
What is Wednesday night?
Thai astrology starts the day at sunrise (about 06:00), not midnight, and splits Wednesday in two: born 06:00–17:59 on Wednesday is Wednesday day; born from 18:00 Wednesday until dawn on Thursday is Wednesday night (Rahu). Anyone born after midnight but before dawn belongs to the previous day.
Yearly lucky and unlucky colours differ between astrologers; this site shows only the traditional birthday colours.
