Tāksā houses for people born on Sunday: Boriwan, Ayu, Decha, Si, Mula, Utsaha, Montri, Kalakini
Tāksā-Pakorn sorts Thai consonants and vowels into eight groups, then lets the day of birth rotate those groups into the eight houses. For someone born on Sunday, the groups land as shown in the table below.
The first seven houses are the auspicious ones; the eighth is kalakini — the group tradition says to avoid in the formal name of anyone born on Sunday. That applies to newborns and to adults considering a change alike, because Tāksā is computed from the name-holder's birth day, not the day the name is chosen.
Kalakini letters for Sunday
ศ ษ ส ห ฬ ฮ
keep out of the name
By Thaksa-Pakorn, someone born on Sunday avoids these letters in their formal name. If the name in use carries even one of them, that name has a letter sitting in the kalakini house.

What each house means
Whichever house a name's letters land in, tradition reads the name as leaning toward that house's affairs. The meaning of each house is the same for every birth day; what changes is which letters sit there — for Sunday, these:
- Boriwanะ า ิ ี ุ ู เ แ โ ใ ไ ฤ ฦ
- Boriwan is the letter group of the birth day itself. Tradition ties it to the people around you — followers, staff, and being someone the family leans on. A name heavy in these letters is described as one that attracts helpers.
- Ayuก ข ค ฆ ง
- Ayu covers life, health, and long-run steadiness. It is the house elders most often weigh when a name is chosen for a newborn.
- Dechaจ ฉ ช ซ ฌ ญ
- Decha covers power, standing, and honour at work. It is one of the three houses tradition prizes most, and the one people changing their name for career reasons usually reach for.
- Siฎ ฏ ฐ ฑ ฒ ณ
- Si covers dignity, wealth, charm, and grace. It is the prized house most often mentioned alongside money and social standing.
- Mulaด ต ถ ท ธ น
- Mula covers foundations, capital, inheritance, and tangible assets — the settled base rather than Si's visible shine.
- Utsahaบ ป ผ ฝ พ ฟ ภ ม
- Utsaha covers diligence, persistence, and what comes from your own effort.
- Montriย ร ล ว
- Montri covers patrons, teachers, and the people who back you up. It is the third of the prized houses.
- Kalakiniศ ษ ส ห ฬ ฮ
- Kalakini is the one house to avoid. These letters are held to be inauspicious for someone born on that day, so tradition says not a single one should appear in the formal name.

Changing your name — born on Sunday (2026)Frequently asked questions
- Which letters are kalakini for someone born on Sunday?
- For Sunday the kalakini letters are ศ ษ ส ห ฬ ฮ, per the rule set DekDuangDee uses on both the website and the app. A formal name for someone born on Sunday should contain none of them.
- What are the eight Tāksā houses?
- In order: Boriwan, Ayu, Decha, Si, Mula, Utsaha, Montri and Kalakini. The first seven are auspicious and the last is the one to avoid. Tradition prizes Decha, Si and Montri most.
- Why is Wednesday split into day and night?
- Thai tradition treats Wednesday as two groups — Wednesday-day (before 18:00) and Wednesday-night (from 18:00) — with different kalakini sets. You need the time of birth to land in the right one.
- Is avoiding kalakini letters enough on its own?
- Clearing the kalakini letters is the first step most people take; after that they look at which houses the remaining letters lean into, plus meaning, pronunciation and sound. All of it is cultural tradition, not a provable prediction.
