How to Calculate actual date when starting date and months is given?

I have a series of starting date starting from year 2012 till 2014, and the period given is 54 months, how to calculate actual date after 54 months?

As below example:
Starting date: 23/4/2013

Period : 54 months

Actual date after 54 months is ?

For the 48 months i can calculate manually the days either is 365 or 366 but the balance 6 months is subject to the starting date fall under which month.
I need to calculate the accurate date from each starting date.
Please help and thank you.

You can try the EDATE function.

E.g., if you have the date (23/4/2013) in cell A1, you can use the formula

Formula:

=EDATE(A1,54)

which should give you 23/10/2017.

Thank you. This is the formula i looking at.
