Try this:

int months = 0;
for (; months< 12; )
{
    td = td.AddMonths(1);
    if (td > next)
    {
        td = td.AddMonths(-1);
        break;
    }
    months++;
}

Insert that just before your "int d..." line. It should give you the number of months, and your day calculation should be < one month.

Problem is, that "a month" is not "a month" but a count of days between 28 and 31.

However, by applying AddMonths you can get fairly close to a uniform and useful method:

DateTime birthday = new DateTime(1980, 11, 19);
DateTime today = DateTime.Today;
int months = 0;
int days = 0;

DateTime nextBirthday = birthday.AddYears(today.Year - birthday.Year);
if (nextBirthday < today)
{
    nextBirthday = nextBirthday.AddYears(1);
}

while (today.AddMonths(months + 1) <= nextBirthday)
{
    months++;
}
days = nextBirthday.Subtract(today.AddMonths(months)).Days;

Console.WriteLine("Next birthday is in {0} month(s) and {1} day(s).", months, days);

Result:

Next birthday is in 2 month(s) and 4 day(s).

Please note, that you have to use `AddYears` as shown to get a precise calculation for the next birthday. — Gustav, Sep 15 '15 at 08:17
