The Principal
Army School
Delhi 6,

Subject:- Application for leave due to function

Respected Sir,

  I am writing this application to inform you that my father has been promoted to the rank of Associate Professor. The whole family is happy and jubilant. My mother has decided to throw a party on this happy occasion. Since it is a memorable moment of my father’s career, I believe that I should be there for him. So, please grant one day leave in my favor so that I can enjoy this moment of joy with my loved ones. I shall join the school immediately the day after tomorrow 

Thanking you
Yours Faithfully
