Chhath Puja, which is celebrated on the sixth day in the month of Kartik of the Hindu calendar, is celebrated to worship Sun God Surya Shashti, or Dala Chhath, and his wife Usha, who is also known as Chhath Maiya. Devotees offer their gratitude to Sun God for his protection and seek his blessings along with good health and happiness.
This year, Chhath Puja started on October 24 and will continue till October 27 and the main puja will be observed on October 26.
The Shashthi Tithi will begin at 9:37 am on October 25 and finish at 12:15 pm on October 26. On the day of the main puja, the sun is expected to rise at 6:41 am, while sunset will likely happen at 6:05 pm.
Chhath Puja has been mentioned in Mahabharat and Ramayan. It is believed that Draupadi along with the Pandavas, upon advice from the noble sage Dhaumya, performed Chhath Puja.
Chhath Puja is celebrated mainly in Bihar and Uttar Pradesh, but with many people from those states moving to Delhi, it has become an important festival in the national capital as well.
