I visited a few temples before it was explained that there are seven different Buddhas or Buddha postures, one for each day of the week. To determine the Buddha or Buddha posture that represents you, you need to know what day of the week you were born. Before you start visiting the temples or Thailand in general, know which Buddha represents you by looking up what day you were born on by just typing your date of birth into Google. My day ended up being Saturday.
Throughout Bangkok and Thailand, you will see the different postures represented, like the Reclining Buddha at Wat Pho which represents those born on Tuesday. Each of these seven poses represent certain significances and different personality traits.
Sunday Buddha – Pang Thawai Net – The Sunday Buddha translates to “Seven Days Looking”. The Sunday Buddha is always in a standing position with its arms crossed in front with the right hand always covering the left. This Buddha represents time soon after obtaining enlightenment after standing for 7 consecutive days in front of a Bodhi tree without blinking.
Being born on Sunday means you are deemed to be respected, wise and loved by friends and family.

Tuesday Buddha – Pang Sai Yat – The Tuesday Buddha is represented by the reclining Buddha which lays on its right side with its head resting on its right hand with its toes perfectly aligned and pointing straight out. This represents Buddha trying to make himself bigger than the evil Asura Rahu to lower the pride of Asura Rahu. In Thia Buddhism, Asura Rahu is the asura (evil being) who is portrayed with a black half body and is usually shown swallowing the sun or the moon. Seeing the size of Buddha in its relaxed position led to Asura Rahu succumbing to Buddha and accepting the Buddhist teachings.
Being born on Tuesday means you are an active person, brave and serious in nature.
