According to Wikipedia:
"Holi (होली) is a colourful and happy Hindu holiday celebrated primarily in India on the last full moon of the lunar month of Phalguna at the end of the winter season. It falls in either late February or early March. It is also known as the Festival of Colours."

At shuktara Holi has a long history - every year everyone at shuktara throws coloured powder and liquid colour in bright, vibrant hues at each other, the staff and friends who come by. For days afterward the colour is still visible on faces, hands, and clothes as it slowly fades. Holi is a wonderful holiday, one that everyone participates in and completely enjoys.
