"so we are to work six day because God created in six unspecified periods of time"

No, you are to work six light / dark cycles because God created the universe in six light dark cycles. You have plenty of empirical data to support that your light / dark cycle is approximately 24 hours, but you have no direct or indirect evidence as to the duration of the light / dark cycles of Creation.
