Khmer Concept of Days in Cambodia

Before we used to THNGAI MUOY ROUCH or THNGAI MUOY KOEUT, we used RONOUCH and KHNOEUT according to the Chanda Gita (the movement of the moon).
Today, we use the elements of the Solar System to name the days of the week. This kind of counting is the Suriya Gita way.
1st day = ADITYA (Read: Atit) Sunday - Sun Color KRAHAM HKCHEI or KRAHAM CHHAS (Dark red or light red)
2nd day = CHANDA (Read: Chant) Monday - Moon Color LOEUNG TUM (Orange or Yellow-Orange)
3rd day = ANGARA (Read: Ankear) Tuesday - Mars Color SVAY (Purple, Violet, Mauve)
4th day = BUDH (Read: Put) Wednesday - Mercury Color SILEAP (Green-Yellow)
5th day = BRAHASPTI (Read: Prahos) Thursday - Jupiter Color TROUY CHEK-BAI-TANG KHCHEI (Green or Light Green)
6th day = SOKRA (Read: Sok) Friday - Venus Color = KHIEV (Blue or Dark Blue)
7th day = Sao-Sunday-Saturn Color PRING TUM )Color of Jambolan Plum or Crimson)
These days have different powers on the life of the living things on Earth. So everything is done according to these days for the best condition and for the right way.
We must wear clothes according to these days (Seven Colors) in formal way, at the official ceremony, or at the traditional ceremony (especially when we go to see the king at his palace in the old time).
