Buddhist Holy Days and Gon Days: 5 Prohibitions on These Powerful Days to Avoid Mistakes!

Many people may have heard elders say, “Don’t cut your hair on a Buddhist holy day,” or “Don’t quarrel on a Gon day.” Have you ever wondered why? It’s not just a cautionary tale, but relates to "energy" , and "life’s timing" that our ancestors have observed for many generations.horoscopeThairath Online Horoscope introduces Gon days and Buddhist holy days along with 5 prohibitions believed to be powerful days when certain acts must be avoided.

What is a Gon day?

A Gon day is the day before a Buddhist holy day (either the 7th or 14th lunar night). It is the day monks traditionally shave their heads, and in belief, it is a day when "the gate to the spirit world opens." Yin energy (cool or dark energy) is especially strong.

What is a Buddhist holy day?

A Buddhist holy day is when sacred energy is at its strongest in the week. It is a day for merit-making, but if one does wrong, negative energy’s effects are multiplied.

5 prohibitions on Gon and Buddhist holy days: Why are these acts forbidden?

1. No cutting hair or nails

It is believed that Buddhist holy days are auspicious, and cutting hair or nails is like shortening one’s lifespan or blocking good fortune.

From an energy perspective, the body undergoes elemental changes on holy days, and trimming excess parts may disrupt balance or cause illness.

2. No sexual activity

Belief holds that holy days are for keeping precepts and purity. Sexual relations disturb mental peace, are thought to cause guardian angels to withdraw, and weaken one’s fate.

3. No quarrels or cursing

It is believed that the mouth is especially sacred on Gon and holy days. Speaking ill or cursing others reflects negative energy back quickly and causes a gloomy mind throughout the month.

4. No committing sins, killing animals, or indulging in vices

Doing sinful acts on holy days is considered far more serious than usual because it violates a time when Dharma’s power is strong—like dirtying a clean place. The resulting karma appears clearly and swiftly.

5. No shady business dealings (on Gon days)

Gon days are believed to be when spirits and negative energies are abundant. Non-transparent dealings are easily obstructed, with a high chance of fraud or loss.

What should you do on Buddhist holy and Gon days to boost your luck?

Chant loving-kindness prayers, especially the Na Metta or Chinabanchorn chants, to increase positive energy and protect the mind. Clean your altar and spirit shrines to welcome good fortune into your home, offering fresh water and fragrant flowers to enhance charm and auspiciousness for a smooth life.
