Hindu religious festivals are widely celebrated throughout India, varying between regional and national levels. Some festivals are determined by the Hindu lunisolar calendar, while others occur annually on fixed dates of the Gregorian calendar.

India’s rich diversity across states, each with its own language, customs, and festivals, ensures that Hindu celebrations differ widely. While certain festivals are observed nationwide, such as Deepavali, Ganesh Chaturthi, Navaratri, and Maha Shivaratri, others remain specific to particular regions, like Vishu, Karva Chauth, and Ugadi.

Advance knowledge of festival dates is crucial for planning festivities and holidays. These occasions play a significant role in uniting families, friends, and communities, fostering a deep connection to ancestral Hindu traditions.
