    For example,

    2008/01/01 and 2008/05/01 = 4

    2008/01/02 and 2008/05/01 = 3

    I got it.

    now and past are DateTime varaiables.

    int monthsApart = 12 * (now.Year - Past.Year) + now.Month - Past.Month;

    if (now.Day < Past.Day)

    {

    monthsApart--;

    }

    You could use timespan

    Timespan ts =  Date1 - Date2

     convert the result to months.

    Using Timespan, the end result will be in days, not in months, and I cannot just divide it by 30 to assume that each month is 30 days.
