URGENT Age / date of birth validation

Hello,

I could really use some help. I am using Classic ASP to develop this.  Can you please help me, I am pretty new to web development?

<input name="SpouseAge" class="text-body" id="SpouseAge" onkeypress ="checkDate(this)" size="8" maxlength="8"> (mm/dd/yy)

I  need to do the two items shown below:
1. Get the users age
2. Make sure they are 18 - 64 years old
3. Make sure they enter a valid DOB in the mm/dd/yy format.

if you write a onkeypress event, every single keypress the validation function will be triggered. No one can write his/her age on a single keypress.

Use onblur event
