Getting this one in 1 attempt is virtually impossible, there's a hidden condition you would never expect (birthdate must be accurate to the millisecond).

Also, be careful if using Boolean.getBoolean(); It didn't behave the way I assumed it did and I wasted a ton of time.

LOL never thought I can pass with 2 attemps, be careful when parsing the Date, using debugger to see it clearly if you don't know why having error.

Be sure to store and retrieve the birthDate in milliseconds. It doesn't say that in the conditions, but validation will fail if you store only the day, month and year.
