What Is Wan Ubat? Why Did Ancient People Warn Against Holding Auspicious Events on This Day? Plus Ways to Avoid It

What is "Wan Ubat"? Why is this day, according to ancient beliefs, forbidden for new beginnings? A deep dive into the prohibitions and remedies to avoid misfortune for spiritual followers.

Explaining the meaning of "Wan Ubat" and why ancient people feared it.

In Thai astrology, the concept of "Kalayok"—determining auspicious and inauspicious days—is deeply ingrained in Thai life and culture. Especially when starting something new, many check the calendar to avoid a day known as "Wan Ubat." Strictly so.

Wan Ubat (pronounced 'U-bad') is classified as an inauspicious day. The term "Ubat" means something evil, unlucky, or an unexpected event. Astrologically, it signifies a day filled with obstacles and difficulties; actions taken on this day are often not smooth and may lead to accidents or financial loss. It is considered the opposite of auspicious days like "Wan Thongchai" and "Wan Athabodi."

Check the prohibitions: why shouldn't auspicious events be held on this day?

According to ancient beliefs, starting something new is like planting a tree; if planted on a bad day, the tree struggles to grow. Therefore, ancient people forbade holding auspicious ceremonies or major beginnings on Wan Ubat, including

  • buying a new car, which is believed to bring accidents or frequent repairs.
  • Registering a marriage or holding a wedding ceremony, which is thought to cause marital problems, obstacles, and conflicts.
  • Moving into a new home or opening a business, which is believed to cause business difficulties, losses, or unrest for residents.
  • Important business negotiations, which may lead to misunderstandings or failed agreements.

Ways to avoid and remedy "Wan Ubat".

For believers, the best way to avoid Wan Ubat is to consult the annual Kalayok calendar before setting important dates. However, sometimes convenience or unavoidable circumstances make avoidance impossible. In such cases, the following remedies can be applied:

1. Use auspicious hours to assist. Although the day is inauspicious, certain time periods within it (such as 'Yam U-Keng') are auspicious. It is recommended to consult an astrology expert to find the most suitable time for ceremonies.

2. Make a major merit before starting the event. Chant prayers, pay respect to Buddha, offer alms, or give charity before commencing important activities to enhance good fortune and dispel negative energy.

3. Rely on the merit of respected elders. If buying a car or moving into a new home, have parents or respected benefactors be the first to enter the house or sit in the car to bring auspiciousness.

Frequently asked questions: Is it okay to hold events on Wan Ubat?

Can you buy a car on Wan Ubat?

Ancient belief strongly advises against it. But if unavoidable, it is recommended to sprinkle holy water from a respected temple on the car and invite a monk to bless it for good fortune. Also, choose a personal auspicious time for driving the car out.

Is it bad to register a marriage on Wan Ubat?

Astrologically, it is considered inauspicious and may bring challenges to the marriage. If possible, postpone the date. If already booked and cannot change, couples are advised to make merit together in the morning and sign the registration during the day's most auspicious time.

Although "Wan Ubat" is traditionally forbidden according to Thai Kalayok and astrology, in modern times personal readiness and convenience are important factors not to be overlooked. Understanding these beliefs helps us plan our lives more thoughtfully and with greater peace of mind.
