I am an happy Indian, and yes, we do celebrate Diwali in our country...
It is basically like a festival of lights.
We decorate our houses with lamps and candles and on the previous night, we create a bonfire...


We even pray to our gods and goddesses. It is actually celebrated as in our myths and legends of our holy books, it is an auspicious day as Ram (an avatar of krishna) returns back to his kingdom after 14 years of his exile in the forest after killing the tyrant ruler, Ravana.
The best and the worst part is people burst firecrackers as though their is no tomorrow (but I never created such pollution, nor do I approve of it...
)
