Durga Puja in the year 2020 began on October 21 with Panchami and continued through October 26 with Vijayadashami as the last day. The main days of celebration included Shashthi on October 22, Saptami on October 23, Ashtami on October 24, and Navami on October 25, 2020. This five-day festival is celebrated annually to honor Goddess Durga, typically in the Hindu month of Ashwin (September-October) according to the lunisolar calendar, but in 2020 notable variations due to a special lunar phenomenon shifted the dates into Kartik month.
