I've changed the formula used to calculate the moon phase if you have not installed pyephem. For 15-Sept-2018, this version gives 37% illumination (versus 24% for the old version).
Interesting project. I learned a lot about lunations and how to calculate the phases of the moon. The root problem is that the time between new moons is not a constant value. So, as time marches on, the approximations get worse and worse. This new version starts with the first new moon of 2018 (16-Jan-2018) and calculates forward from that.
