Description

Package with a few extra astronomical / calendar / epoch features that mathematica does not have.

supports multiple calendars (julian, gregorian, synodic, anomalistic) supports JDN conveniently, shows moon phase est. NEW: supports day number from 0 of any calendar too many (new/different) functions to list.

conversion all-way between supported calendars

supports multiple epochs and epoch generation convert between some epochs without calendar support ie, J2000.0, JDN create new epoch with a datum + other epoch (can work with TAI/clock epochs but cannot import TAI from solar only)

done all throughout with arbitrary precision (many new functions that add a few new features in all)

timeDeduce is a minor extra: deduce and show other times / angles, from simple time equations, but hardly tested (new).

quick examples:

{PrettyDate[], PrettyDate[calendarChange2[Date[], gregorian, julian], julian], MoonPhase[]}

{"Saturday, July 12 2014. 6:38:20 p.m. -4 GMT", "Friday, Iunius 29 2014. 6:38:20 p.m. -4 GMT", "Full Moon"}

timeDeduce input: GMT,lon,tz,arieslon output: input + SHA,Ra,LHA ; (* is in dn and tm or ang *)
