Thai culture stories for Monday
Monday: the Moon, the horse, and a day of yellow
Monday (วันจันทร์, wan Chan) belongs to the Moon, and its guardian animal is the horse. Monday’s color is yellow. Some sources describe the moon deity’s body as white or cream, but the weekday color chart most widely used in Thailand assigns yellow to Monday. On the taksa diagram the Moon sits in the east and is number 2.
Monday’s Buddha image shows the Buddha stopping a quarrel among kin, Pang Ham Yat (ปางห้ามญาติ). Some sources call the same posture Pang Ham Samut (ปางห้ามสมุทร). The tale goes that relatives were fighting over river water when the Buddha appeared and, raising both hands, brought the dispute to an end. The image is known for the hands held out in front, and a scene of calming angry hearts is said to match the quiet mood of the Moon.
Monday’s yellow is one of the most visible colors in everyday Thai life. For a long time it was common to wear a yellow shirt in honor of the late King Bhumibol, who was born on a Monday, and plenty of office workers and students still wear yellow on Mondays. For that reason yellow is often read as a color of respect and warmth.
The question the Monday star offers is closer to “Am I looking after my own heart, too?” The Moon waxes and wanes, so its image is used for the ebb and flow of feelings and for time to rest. It does not decide your mood or your character today. Please meet it lightly, as one cultural symbol.
In the taksa, the planet of Monday takes the first seat and the eight bodies are laid out in a fixed order. The chart for someone born on Monday places the Moon in the seat of The People Around Me, Mars in Life Force, Mercury in Influence, Saturn in Fortune, Jupiter in Foundation, Rahu in Effort, Venus in People Who Help You, and the Sun in What to Watch Carefully. This layout is carried over from a published traditional table, and this site only reads the color of each planet from it. Please remember that astrologers interpret even the same table differently, and that no seat is fixed as good or bad.
