Hi. I am having problems finding the age of a person using today's date (user input) and their birthday (also user input). I have created my code but it doesn't give the correct answer. I am having a problem getting an accurate age. Here is my code below:

' Program:   Hours and Years Slept
' Author:    Jacquelyn Donnelly
' Date:      September 19, 2010
' Purpose:   This application calculates and displays
'            the total amount of hours slept in the user's
'            lifetime in years, months, days and hours.

Option Strict On

Public Class frmHoursandYearsSlept
    ' How many days in a year - used in multiple procedures
    Const _cintYearInDays As Integer = 360
    ' How many months in a year - used in multiple procedures
    Const _cintYearInMonths As Integer = 12
    ' How many days in a month - used in multiple procedures
    Const _cintMonthInDays As Integer = 30
    ' How many hours in a day
    Const _cintDayInHours As Integer = 24
    ' How many hours slept in a day
    Const _cintSleep As Integer = 8

    Private Sub frmHoursandYearsSlept_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ' This even handler is executed when the form is loaded
        ' It displays the heading, clears the text property of the
        ' Total Years, Total Hours, Total Months and Total Days labels
        ' and sets the focus on the txtFirstName text box object.

        Me.txtFirstName.Focus()
        Me.lblTotalDays.Text = ""

        ' Then, it sets the focus on the txtFirstName text box object.

        Me.lblDaysSlept.Visible = True
        Me.lblMonthsSlept.Visible = True

    End Sub
End Class

The program runs fine, but gives garbage as result. I am new at this and have been looking for a solution. We haven't covered IF statements yet. I have seen a lot of answers with DateDiff but we haven't gone over that either and I'm not sure how to implement it. If anyone could point me in the right direction I would very much appreciate it!

Thanks
