Pick Birthdays between 2 dates Irrespective of Year of Birth in C#

Many times we come across situations where we have to get birthdays of employees between 2 given dates irrespective of year of birth.

Here is a small piece of code in c# that does the trick:

public bool IsBirthdayBetweenDates(DateTime birthdate, DateTime beginDate, DateTime endDate)
{
     if (birthdate != null & beginDate != null && endDate != null)
     {
         DateTime temp = birthdate.AddYears(beginDate.Year - birthdate.Year);

         if (temp < beginDate)
         {
             temp = temp.AddYears(1);
         }
         return birthdate <= endDate && temp >= beginDate && temp <= endDate;
     }
     return false;
}

Here beginDate is the start date for search
endDate: end date for search

The logic is simple,Just bring the birthdate to the year of begindate by adding years and then compare the dates.
