My favourote holidays are related to Indian and non Indian festivals.

Top three would be
1. Festival of lights (Diwali).
-celebrated on the beginning of the first month of the Hindu calendar/ Hindu New year. (Falls between 20th October and 10th November usually)
-is celebrated by lighting up the entire home and vicinity with tiny lamps, lanterns and diyas.

2. Kite Flying Day (also called Makar Sankranti)
-celebrated by filling up the skies with colourful kites, and old folk music of India playing in the background)
-marks the day after or around winter solstice to celebrate the increase in daylight in the days to follow, with colour music and life.

3. Laughter day (10th January).
Not a holiday... But a day when people all over the world, who believe in it and know about it, celebrate it.
It is a day that is based on the science that, expression has an effect on the mood.
