expired field in module account and report on calendar

[Matteo87]

Hello everyone,
and sorry for my english.
I have a problem and I hope you can help me.

In the module companies (account) I would like to insert a type called expiry date. In practice it would be a kind of field "calls or meetings" because each due date should be stated on the form calendar.


Example
In the tab company, I go to fill a field called date-type term visits.
Once saved, if I go in the calendar module, I can see the expiry date I entered.

I do not know if my son explained well.

How to create and report this? Some of you might help me?
Greetings
Matthew
