22nd June Friday is Ganga Dasahara/Papahara Dasami
The holy River Ganga came down to Earth on Jyeshta Sukla Dasami. Hence it is named as Ganga Dasahara or Papahara Dasami. The scriptures talk about several yogas in reference to this day. 1. The month of Jyeshta 2. Suklapaksh ( Waxing fortnight) 3. Dasami Tithi 4. Wednesday 5. Hasta Nakshatra 6 Vyatipata Yoga 7. Garaja Karana 8. the Moon in Kanya 9. Sun In Vrishabha Rasi 10. Ananda yoga( Hasta on a wednesday). All of these are not possible together. So whatever maximum of these happen on a Dasami is celebrated as Papahara dasami. There is an opinion that Dasahara shall be celebrated even in Adhika maasa.
If you are in Kasi you should take a dip in Dasaswamedh ghat on this day. In other places bath any nearby river with Ganga puja.
After bathing, one should pary to Gangaji with salutations Dasapapharayai Bhagavatyai Gangayai Namo namah:, one should then pray to Narayana, Rudra, Brahma, Surya, Bagirath and Himachal to remove efects of any evil karma.
It is customary to feed ten Brahmins and ten Sumangali ( Suhagan) ladies on this day.
