Maka Bucha is the second most important Buddhist festival in Thailand

Although the events of Maka Bucha date back over 2,500 years to the time when Buddha was teaching, this day was only designated as a holiday in Thailand in 1957. Before 1957, the third lunar month was observed as a Buddhist Holy Day.

This festival ranks as the second most significant celebration in Buddhism. The date of this festival, like many others in Buddhism, is determined by the Lunar cycle. The holiday is also referred to as Magha Puja or Lord Buddha Day.

On this day, the full moon of the third lunar month, known as Tabodwe, marked seven months since Buddha commenced his teachings, drawing over a thousand monks to listen to his sermon.

In the morning, numerous Thai individuals rise early to offer alms to monks. In the evening, temples are bustling with individuals gathered to hear sermons. They frequently engage in a ritual referred to as the candle ceremony, during which they walk clockwise three times around the temple. grasping blossoms, fragrant sticks, and a flickering candle. Each of the three circuits symbolizes one of the three jewels, which are the core concepts of Buddhism: Buddha, Dharma, and Sangha.

Makha Bucha has been observed in contemporary Thailand since the era of King Rama IV, who reigned from 1851 to 1868. Initially, it was observed solely on the grounds of the royal palace, but it later gained national recognition before being established as a Thai public holiday in 1957. The Thai government has enforced a ban on alcohol since 2015.

Buddhists refrain from consuming alcohol and drugs on Makha Bucha Day. The prohibited behaviors encompass gambling, deceit, gossip, causing harm to other living beings, consuming meat, engaging in sexual promiscuity, and theft. Even Buddhists who are not particularly devout may choose to refrain from eating meat and drinking alcohol on this day.

Chakri Day, National Holiday, 6 Apr Sunday

Kings of the Chakri Dynasty

Thailand's people celebrate Chakri Memorial Day on April 6 to remember the start of the Chakri royal dynasty in 1782, which is still in power. This is also a day to honor the Chakri kings for their important roles in Thailand's history.

What if April 6 falls on a weekend? The holiday will still happen on the following Monday. Keep in mind that the holiday falls on the day that Rama I was crowned king.

It wasn't long after the Chakri dynasty began before its first king, Rama I, made Bangkok the capital city of Thailand. In this way, the holiday can be seen as having extra meaning for people who live in Bangkok.

Rathod, the tenth Chakri king, is still in charge today. On Chakri Day, he and the rest of the royal family lead special services at the Royal Chapel. They also pay their respects to past Chakri kings at the Royal Pantheon and lay a wreath by the statue of Rama I.

Songkran, a popular three-day festival, starts just a few days after Chakri Day. This is a very happy time of year in Thailand.

Anniversary of the Death of King Bhumibol National holiday, 13 Oct Monday

In Thailand, October 13 is a public holiday to honor the day His Majesty the Late King died.

People in Thailand only knew King Bhumibol Adulyadej for many years. He stayed in power even as many prime ministers and military coup leaders came and went. He was seen as a stable figure, and the people who lived in his realmhim very much.

He was born on December 5, 1927, and died on October 13, 2016. He became king in 1946 and ruled for 70 years. People called him "Father of the Nation." He finally died at the age of 88, after a long battle with illness.

After a year, the king was burned at the stake and his body was taken to Phra Merumat on a restored golden royal chariot as part of a long and complicated ceremony. There, he was buried with many of his ancestors from the Chakri Dynasty, which began in 1782. All over the country, shrines were built in honor of the king, and people were sad for a whole year after he died.

Chulalongkorn Day National holiday, 23 Oct Thursday

King Chulalongkorn

He was the fifth Chakri king of Siam and one of its greatest.

Thais honor the great monarch by placing wreaths and flowers at the Rama V Statue in their hometown on this day. The Ministry of Interior orders provincial governments to commemorate King Chulalongkorn.

King Bhumibol's Birthday/Father's Day National holiday, 5 Dec Friday

This national holiday in Thailand is held annually on December 5th.

If December 5th falls on a weekend, the holiday will be observed on the following Monday.

The late King of Thailand, Bhumibol Adulyadej, had a birthday on this day. Thailand's National Day is also on this day, which is also Father's Day in Thailand.

The holiday itself is full of bright colors. All over Thailand, buildings will have flags, bunting, and portraits of the late King on display. In the Grand Palace area of Bangkok, the streets are lined with thousands of marigolds.

Yellow is the main color of the celebrations because the King was born on a Monday, and in Thailand, Monday is yellow. This is why marigolds are chosen for their color.

The streets around Ratchadamnoen and Sanam Luang are closed to traffic in the evening, and a lot of people come to watch the fireworks shows.

On this holiday, most government offices are closed, and all banks are closed except for branches in shopping malls. During this holiday, it is not illegal to sell alcohol.

Constitution Day, National holiday, 10 Dec Wednesday

When Thailand's first permanent constitution was signed in 1932, December 10 is Constitution Day, a time to remember that event. Since the holiday is close to the late King's Birthday on December 5, some people take a few days off to make it a long break and enjoy both holidays.

Thai people have always called their country "Mueang Thai," which means "land of the free." However, people from other countries used to call Thailand "Siam." The monarchy has also been around for a very long time. Early Thai kingdoms that stood out were the Kingdom of Sukhothai, which began in 1238 A.D., and the Kingdom of "Ayutthaya," which lasted from the 1300s until it was destroyed by Burma in 1767.

This new kingdom, on the other hand, began with the Chakri Dynasty in 1782. Its capital was Bangkok, and its first king was Rama I. All of these were absolute monarchies. The constitution of 1932 and later ones put more power in the hands of the people's representatives in government and limited the power of the monarchy.

Thailand went through a lot of economic and political change in the 1920s. Then, in 1932, the military, the police, and the intellectual class went to king Rama VII and asked that he be limited in his power. People stopped believing in the king's ability to lead the country because he was too young and there wasn't enough democracy. At first, the king said no, but on December 10, 1932, he finally gave in. The king lost almost all of his power, but his position as king was kept safe.

There have been 20 more constitutions of Thailand since then, but the monarchy has lived through all of them. Bangkok's king is still respected as the official leader of the country, the head of the military, and the "upholder of all religions."

In line with the Gregorian Calendar, Thailand celebrates January 1 as New Year's Day. This is on top of Songkran, the traditional Buddhist celebration of the new year in the middle of April.

Many Thai people who live in cities or somewhere other than their hometown will use the end-of-year holiday to go back to their hometown and see their parents and other family members who still live there.

Thailand has "New Year countdown events," school events, corporate parties, musical concerts, and fireworks shows all over the country. In Bangkok, there is a very large gathering by the Central World mall.

A lot of religious Thai people will still go to temples to "make merit," which means they will give money or gifts to the monks, listen to religious talks from the monks, release birds or fish in a ceremony, or go on "meditation retreats" for the New Year.
