Thanks ! It has given a idea. But actually when I proceed further I find that my problem is different.


I have tried to work with the help provide by you. For calculating months and days the help is ok. But while I was trying to solve the problem relating to banking I
failed to find the exact result. By using help of you & Vladimir Zografski
I am getting different results.Let me consider them one by one.

Rich Pupko Vladimir Zograski
month Days Month Days

d1=(12/01/2005) 11 31 0 364
d2=(11/01/2006)


if d2=(12/1/2006) 11 32 0 365
if d2=(13/1/2006) 12 2 0 366

but where
d1=(12/12/2004)
d2=(12/03/2006) 14 29 3 365


But in our banking system we simply count one year for the period from (1201/2005) to (12/01/2006) and (12/01/2006) is the payment date.
For the given last period the period of deposit is one year 3 months or 15 months.Please help me.
