Sia was literally 17 years older, that means she was born on August 15, 1990. This is a Wednesday which matches with John's birth date.

    $\begingroup$ I just looked up 2007 August calendars and 1990 August calendars to determine the day of the week :) @DiculSmerd $\endgroup$ – QuantumTwinkie Feb 11 at 15:22
