  • What do the moon phases mean? At new moon the moon stands between sun and Earth and cannot be seen. A week later it is half lit (first quarter), after about 15 days it is full, and then it wanes to the last quarter. One cycle takes 29.5 days on average.
  • How accurate are the times? They are computed with Jean Meeus' formulas and accurate to a few minutes – for New York in local time, daylight saving included.
