We celebrate all the festivals here. But the most important and exclusive festival at Bihar is the Chhatt Puja
It is a 4 days festival where people nearly don't eat anything
First day Naha kha where the person eats after having a bath and generally eats only once in the entire day
Second day is Kharna when it is a fast (not even a drop of water ) since morning n people eat in the evening only during the time moon is there (it's on 4th day after Diwali/Amavasya so moon is there for very small duration) and while eatine there can't even be a single voice heard or else you need to leave the food immediately
The third day is a complete fast with no food or water. In the evening the people who are doing chhatt would go in water (preferably Ganga river) and worship the sun during sunset it's probably the only festival in the world where doobte suraj ki pooja hoti hai.
The fourth day in the morning after worshipping the sun during sunrise the festival ends
And yes the people who are fasting for this festival aren't allowed to sleep on bed they can sleep of a bed sheet or a blanket etc. And one person can get only one blanket either use it to keep on the ground or to wrap yourself
