Surya Shasthi Puja- The Worship of Sun God
“Surya Shasthi Puja” (also known as Chhath) comes after “Deepavali” on “Kartik Shukla Paksha Shasthi” which coincides with October- November. “Chhath” is celebrated twice in a year “Kartik Chhath” is more important because fasting is easy in this month. The second occasion comes in the summer season in March- April which is called “Chaiti Chhath”. Waterless fasting is difficult in the summer season.
