Time zone. The current moon calculations are based on your computer's clock, which is assumed to be correctly set for your time zone (date and time)
A 'lunation' i.e. the cycle from each new moon to the next one takes 29.5305882 days, but the actual orbital period of the moon is only 27.3217 days. That is the time it takes the moon to return to approximately the same position among the stars.
A 'moon day' i.e. the time interval between two successive earth meridian crossings, is approximately 24 hr. and 50 min.
A meredian crossing is also called 'southing of the moon'
Waxing means growing.
Waning means shrinking.
Gibbous is more than half but less than fully illuminated.
