Dates of New Moon:
To use the night-by-night charts of the Moon in these web resources and in the Turn Left at Orion Moon chapter, you need to know how many nights you are into the lunar month.
To learn that, count backwards from tonight’s date to the most recent Full Moon date in the table below.
Remember that this calculation is only approximate, for a couple of reasons. First, these dates are in UT (roughly the same as Greenwich Mean Time) - not necessarily for your time zone. Second, the non-circular orbit of the Moon produces librations (apparent wobbles) of the Moon that can advance or delay the appearance of lunar features by up to about a day.
