New Moon Dates -Calculates moon date and time lunar latitude for a given year.
Version: 2.0Calculates and displays the Date, time and Lunar Latitude per month for a given year (includes offsets from Prime Meridian and either UT or local time).
Operating System: Mac OS X
The routines are written in BASIC, are not object oriented and make some assumptions about both software and hardware platforms.
Lunar orbital accuracy is a non-trivial task. The equations for New Moon Dates are derived from the equations used in the book: "Astronomy with Your Personal Computer" by Peter Duffett-Smith.The accuracy claimed in the book is accurate to within two minutes (page 172 of the second edition). The information that New Moon Dates displayes is the date of the New Moon and the New Moon's latitude, but only you can decide if this is accurate enough for your needs.
