On July 4, 2025, Assumption College held a traditional candle casting activity in celebration of the upcoming Buddhist Lent. Representatives of parents, students, school administrators, and teachers joined hands in creating two elaborately crafted Lent candles.

   Continuing this meaningful tradition, the school organized a formal candle offering ceremony on July 9, 2025, at Wat Muang Khae in Bang Rak District, Bangkok. The event aimed to preserve Thai cultural values and foster spiritual awareness among students, while strengthening the connection between the school and the community.
