Koh Samui’s Major Holidays

Holidays in Koh Samui are categorized into four types: traditional, royal, Buddhist, and tourist holidays. How they are celebrated differs, such as banks closing on public holidays, businesses reopening, or all businesses and government offices being closed on major public holidays.

Whether it’s a significant holiday or not, these dates and occasions offer festive and exciting times to come and enjoy a vacation on the island.

Traditional Thai holidays are celebrated nationwide, including Songkran and Loy Krathong. Songkran will be celebrated from April 13 to 15, 2025, and it’s considered the Thai New Year festival. Locals throw water at each other on the streets to symbolize the cleansing of bad luck.

On the other hand, Loy Krathong is celebrated in November and is taken as the 2nd most well-known holiday after Songkran. It’s a Buddhist holiday where locals have small banana leaf containers floating on the river.

2. Royal Holidays

Royal holidays are usually the birthdates of the royal family of Thailand. This includes the King’s Birthday on July 28, Queen Sirikit’s birthday on August 12, and the commemoration of death anniversaries of past royals. Some activities held during royal holidays include ceremonies, religious traditions, and cultural shows.

3. Buddhist Holidays

Thailand consists of over 90% Buddhists and some of its most important holidays are Buddhist traditions. The Makha Bucha, for example, is held every February or March, commemorating the gathering of over 1000 monks to hear the teachings of the Buddha. The Visakha Bucha, held every May or June, celebrates the life of Buddha, which includes his birth, enlightenment, and death. The third most crucial Buddhist holiday in Thailand is the Asalha Puja, commemorating Buddha’s first sermon and the introduction of the Four Noble Truths.

4. Tourist Holidays

Tourist holidays include Christmas and New Year, which are not part of Thai culture but are still celebrated and considered national holidays.
