Write An Application To Manager Regarding Leave For Daughter’s Marriage In English

To 
The Manager
Subject: Request of leave for daughter’s marriage

Sir/Ma’am

My daughter’s wedding has been fixed for 20th June. I am writing this leave application in advance so you can give me a long leave. I have also attached an invitation card for you. It would be more than enough to have two weeks for this occasion in my life. 

I will be very grateful to you.

Sincerely
Arpita Dwivedi
