Holi, the liveliest of all Hindu festivals, marks the end of the winter gloom and rejoices in the bloom of the spring time. It falls at the end of this week on 3 March.
The night before full moon, communities gather around huge bonfires to sign and dance and burn residual debris of winter.
Singing and dancing continues into the next day when coloured powders are thrown over everyone in merriment. People, young and old are drenched in colour.
The BBC has information on the festivals as well as curriculum ideas.
