Why evening and morning, not morning and evening?

And there was evening, and there was morning—the first day. Genesis 1.5b NIV

Ever wonder why the evening is stated before the morning? Normally we'd say we work from morning to evening, right? Was God doing these things at night?

All I can figure is that it was dark when he started--before the light was born. As that was the original condition, it gets first billing. Or maybe it's because God reckons the same as his chosen people, the Jews.
