Raksha Bandhan is celebrated on the full moon day of the North Indian Hindu Calendar
(July-August). It is the Hindu Sister's Day when brothers and sisters reaffirm their bonds of affections. Sisters tie colorful threads or rakhis on their brother's wrists. The brothers, in turn, promise to protect their sisters and give them gifts.
The sister-brother relationship symbolized by the rakhi represents more than the immediate ties of brothers and sisters. It also represents the shared connections of a harmonious and intertwined social order.
