Guru Purnima holds profound spiritual and cultural significance across India. For Hindus, it marks the birth anniversary of the sage Ved Vyasa, the revered author of the Mahabharata. Buddhists observe this day as Dhamma Chakra Day, commemorating the Buddha's first sermon after attaining enlightenment. Jains celebrate it as the day Mahavira's first disciple attained omniscience. The simultaneous occurrence of the Full Buck Moon, a supermoon, adds an astronomical dimension to these spiritual observances. However, the monsoon season across much of India presents a challenge for optimal viewing of this celestial spectacle. Despite potential cloud cover, regions like Ladakh, Rajasthan, and the Rann of Kutch are expected to offer clearer skies, providing a better chance for enthusiasts to witness the larger and brighter moon. The best viewing window is anticipated to be between 8 PM and 10 PM IST.
