Wesak, also known as Vesak or Buddha Day, commemorates the birth, enlightenment, and passing away of Gautama Buddha. It is celebrated on the full moon of the lunar month of Visakha, usually in May. Buddhists celebrate by visiting temples, meditating, chanting sutras, bathing statues of Buddha with water, and emphasizing vegetarian meals, simple gifts, and donations to the needy to honor the Five Precepts of non-harming and non-excess. The significance of Vesak lies in recalling Buddha's enlightenment and spreading his universal message of peace, wisdom, and a path from fear and hatred to true love and happiness.
