Thai lucky days: which day is a good day?
Wan Nai Dee (วันไหนดี, “which day is good?”) is a free Thai website that answers the question Thais ask before moving house, buying a car, getting married or opening a shop. The good and bad days come from the Kala Yok (กาลโยค) in the official Songkran announcement for the Thai year 2569, which runs from 16 April 2026 to 15 April 2027. The site is in Thai; most pages can be switched to English with the EN button.
Good and bad days of the week, 2026–2027
| Day | In the Kala Yok | Meaning |
|---|---|---|
| Saturday | วันอธิบดี (Athibodi day) | Lucky: a day of greatness and authority. No bad day falls on it this year. |
| Monday | วันธงชัย (Thong Chai day) and วันโลกาวินาศ (Lokawinat day) | Lucky for victory and success, but also the Lokawinat day: start at 09:00–10:30 and finish before 10:30. |
| Sunday | วันอุบาทว์ (Ubat day) | Avoided for starting ceremonies and auspicious events. |
| Tuesday to Friday | Ordinary days | Neither lucky nor unlucky in the Kala Yok. |

Good hours
Every day, 09:00–10:30 and 16:30–18:00 are good hours for an auspicious start. We calculate them from the Kala Yok formula; they are not part of the official announcement. Good hours of the year.
Lucky colours by day
From Sawatdiraksa, the poem by Sunthorn Phu: Sunday red, Monday cream white, Tuesday purple or indigo, Wednesday orange, Thursday green or yellow, Friday cloud grey, Saturday black. Lucky colour of the day.

What we don't claim
The days on this site are the general almanac for everyone, not a personal horoscope, and no day guarantees luck. For an important ceremony many Thai families also ask a monk or an astrologer. About Wan Nai Dee and its sources.
