How To Calculate Someone's Age Based On Birthday
> Here we consider how to Calculate Age From Birthday.
> For that we have to compare the Birth Date with respect to the Current Date.
> Suppose One person's Birthday is on 12/2/1998.
> And we wants to calculate the age of this person.
> First of all, get the Year of the Current date -
Current Year.
> Second get the year of the Birth date. -
Birth Year.
> Then just subtract the Current Year from Birth Year.
> Assign the difference to an integer variable
age.
> Now we can do the following comparison for getting the exact age.
if (birthDate > todayDate.AddYears(-age))
> After Comparison, if birthdate is greater, then subtract one from the current age.
> The full code is as follows.
DateTime birthDate = Convert.ToDateTime("12/2/1998");
DateTime todayDate = DateTime.Today;
int age = todayDate.Year - birthDate.Year;
if (birthDate > todayDate.AddYears(-age))
age--;
