Question

why we should tell the national anthem in 52 seconds ​

Answer 1

Answer:

I don't know about that but we sing it in 52 seconds

Answer 2

Answer:

Because that is how long it takes to recite it. There is a tempo that needs to be maintained while reciting it. Exceeding 52 second won't land you in jail.

Prime example is the National Anthem that plays at PVR Cinemas. That is disrespectful. They 'sing' it like it is a song! Especially the lady, giving it variations!
