There are hundreds of festivals throughout the year in India! Here are a few that I am particularly interested in.
Holi Festival of Colors! It is one of the most popular festivals of the country. This year the festival will be celebrated on March 27 according to the Hindi lunar calendar. I can look forward to spraying colors, dancing on traditional Holi songs, rhythmic drum beats and wild processions. The festival is associated with various legends but the most popular among them is the tale of Hollika.http://www.holifestival.org/holi-in-india.html
Deccan Festival: A 5 day festival in Hyderabad starting on February 25. Deccan culture is highlighted in arts, crafts, and Nawabi cuisine. There are also poetry readings, singers, and dancers.
Makar Sankranti: Celebrated in mid-January to commemorates the beginning of the harvest season and cessation of the northeast monsoon in South India. It marks the end of an “inauspicious phase” which according to the Hindu calendar begins around mid-December. Scientifically, this day marks the beginning of warmer and longer days compared to the nights. Each day of the festival has different rituals and festivities to take part in.
International Kite Festival: Traditionally held at Ahmedabad/Gurajat on January 14 (coincides with Makar Sankranti). The festival is a time of thanksgiving for the religious, since it marks the awakening of the gods from their long slumber. The festival draws expert kite-makers and flyers not only from cities of India but also from around the world. Designer’s Kites of infinite variety are displayed at the venue.
