Just a question came into my mind . Since I belong to North India for us Karwa Chauth is the most important.
I think Maharashtrian don’t celebrate karwa chauth so this must be as special as karwa chauth or Teez . Everyone in my family celebrate vat Savitri except me ( since my in-laws family don’t follow the ritual yet I always had a choice to follow it ) . As a kid I observed that vat Savitri is not as important as karwa chauth for North Indian but they do celebrate it .
