Hindu festivals and celebrations focus on happiness

Hindus have no festival which is indicative of a state of mourning.  One can give felicitations to a Hindu on any day of mass-celebration. Hindus do celebrate the birthdays of Ram and Krishna with great pomp and show but do not remember even days of their demise. There are three great festivals of Hindus-

1. Vijaya Dashmi

2. Deepavali

3. Holi or Holika or Holaka
