What is the difference between hoisting the flag on Independence

*First difference*

On the occasion of 15 August Independence Day, the flag is pulled up from the bottom by a rope, then unfurled, which is called flag hoisting because it is done to honor the historical event of 15 August 1947 when The Prime Minister did this. In the constitution it is called Flag Hoisting in English.

whereas

On the occasion of 26 January Republic Day, the flag remains tied at the top, which is unfurled, in the constitution it is called Flag Unfurling.
