Buddha's Birthday, known as Seokga Tansinil in South Korea, is observed on the 8th day of the 4th month in the Korean lunar calendar. The holiday is a significant celebration in the Buddhist religion and holds particularly high importance in South Korea where over 22% of people identify as Buddhist. While the exact date varies each year due to differences in the lunar calendar and the Gregorian calendar, it typically falls in May.

During Buddha's Birthday, the whole of South Korea turns into a festive mood with temples adorned with colorful lanterns and lively events taking place. Buddhists make special food offerings at home and at temples and perform Ancestors Memorial Services. Some temples also hold Lotus Lantern Festivals, known as Yeondeunghoe, to pay tribute to Buddha, where participants light lotus-shaped lanterns. This represents the enlightenment offered by the Buddha.

On this day, it is common for people to visit temples to pay their respects and join the celebrations. Various cultural and traditional programs such as rituals, exhibitions, and folk games are conducted in the temples. Additionally, in the days leading up to the holiday, practitioners often participate in 'street bathing Buddha ceremonies' where a statue of the child Buddha is paraded and adorned with offerings. Buddha's Birthday in South Korea is not just a religious holiday, but a cultural event that brings people together in joyous celebration.
