Dear Mr [surname],
This is to inform you that I am going to be married on December 3rd in Hyderabad. During this occasion, I would like to spend some days with my family, so I would like to leave here on November 28th and return on December 9th.
Please grant me leave for this period and wish us well.
Thank you for your consideration.
I am glad to inform you that my sister's marriage has been fixed for date
Hence please grant me 8 days leave from date(date to date).
I would like to request one day's leave on 16th May, because it is the occasion of my cousin's engagement. Thank you very much for your assistance.
Best wishes, Clive
With due respect it is stated that I can't attend my office duties or any other duties because I have to attend a marriage ceremony of my younger sister. I would be highly obliged if you sanction me leave from 24th Nov to ....
