I grew up in a Sabbatarian religion where we practiced Sabbath observance as a matter of law. My religious community was conscious of the minute that the sun set on a Friday evening. We made sure that moment didn't catch us still at work or at the grocery store. It was expected that we would make every effort to ensure we were adequately prepared to rest from physical labors. Our homes and cars were cleaned, errands were run, and food was prepared.
