Resignation Notice - Company Notice Period

Dear all,
I am working in the Administration division of my company. I want to know that while accepting a resignation, if a person has given one month's notice which is as per the requirement of the company, how can we count the notice period for eg. somebody has given resignation with one month's notice on 5th Feb. 08, when will his notice period be completed, on 4th of March or 5th of March. Generally, we take it one day prior in the next month. Is it correct?
I also want to know that can we accept resignation on a back date.
Regards,
Jyoti Negi

Dear Sender
In this case, you can consider the date of 4.3.2008 as one month notice period completed.
If management wishes to relieve the employee, then there is no problem in accepting back dated resignation letters.

Dear Jyoti,
If someone has suppose given the resignation today i.e 5th Feb then his last date would be 5th March only. But incase if the person has completed his tasks prior then it will be advisable to releive the person depending on the date when he/she has completed his assignments.
