subtract two datetime

I use these following codes in the winform for subtracting two datetime. these are complete datetime which includes day and month and year in it. I want to know how can I subtract two date time only with day and month. For example subtract of 5/12 and 6/12 without any year in it.

        DateTime date1 = new DateTime(byear, bmonth, bday, 0, 0, 0);
    DateTime datenow =  DateTime.Now;
TimeSpan timeSpan = datenow - date1;

Please give me some codes so that I can subtract two datetime with its day and month.

Thanks in advance

You can use some default year like datetime.now and do the subtraction like normal. This wouldnt work for non leap years though as 2012 is leap year.

 DateTime dt1= new DateTime(DateTime.Now.Year, month1, day1);
 DateTime dt2= new DateTime(DateTime.Now.Year, month2, day2);
 TimeSpan t= dt1 - dt2;

Try this:

int year = DateTime.Now.Year;
DateTime dt1 = new DateTime(year, month1 , day1);
DateTime dt2 = new DateTime(year, month2,  day2);
int days = (int) Math.Round((dt1 - dt2).TotalDays);
