In India, we have multiple festivals around the year -
1. Holi. This festival signifies the victory of good over evil when Prahlad defeated Holika. It is mainly celebrated in March
2. Durga Puja. This festival is mostly of my state, again it signifies the victory of good over evil when Goddess Durga defeated Mahishasur. It is mainly celebrated between October - November
3. Krishna Janmashtami. This festival signifies the birth of Lord Krishna, the eighth avatar of Lord Vishnu. As he was born on midnight 12, the days of this festival changes year after year. It is mainly celebrated in August.
4. Raksha Bandhan. This festival signifies the brother - sister bond. The sister ties a "Rakhi" around her brother's hand while her brother gives her the promise to protect his sister forever. It is mainly celebrated between August - September. This festival is also known as Rakhi. Fact: I was born in the Rakhi of 2009 🙂
5. Diwali. This festival signifies the return of Lord Ram, Goddess Sita, and Lakshman in Ayodhya after their 14 years exile in the forest. It is mainly celebrated in November. Durga Puja and Diwali are celebrated side - by - side.
Note - These all are religious festivals. As there are multiple religions in India, each religion has its own customs, religions and beliefs
