If you subtract the number of months or days from the end date, you will get the start date. There's methods on the DateTime class to AddDays, I'm not sure about months, but if you mean literal months ( irrespective of how many days they had), you can just use the existing day and change the month, right ?

thanks for your reply..
yes there is a method DateTime.Now.AddMonths, but in this case, I want to Subtract months from current date.
Day and date is not a problem, I just want to calculate months and years (an estimated start date).

You can still subtract months using the DateTime.Now.AddMonths method. Just use a negative value, i.e. DateTime.Now.AddMonths(-3) would subtract three months. I believe this works the same for the other Add methods too.
