How To Determine The Accuracy Of Ancient Moon Phases? (Answer: Read On!)

I am doing research for the period of 1446 BCE - 960 BCE.  I have created a timeline of events and now I am attempting to add the moon phases to the timeline.  I just last week purchased the Starry Night Pro Plus 8.  I had been using the free Stellarium software up until this download.  What I am puzzled by is that the moon phases do not match at all.  Some are off by days, and others are off by hours.  For instance, on April 27, 1446 BCE in Stellarium the 1st quarter is at 4/27 12:17:3.  In Starry night is shows 4/27 10:12PM (1447?).  I love the ease of clicking on "show events" in Starry night, but the inaccuracy will have me using Stellarium to complete this portion of the project. Is there something that can be done to correct this discrepancy?  In fact, I could not even find the Full Moon on March 7, 1446 in Starry Night. In Stellarium it is shown to be March 7, 1446 1:42:35.  And is there some way to add the seconds to the time?  I have found that the seconds are important information to verify calculations.  Thank you.  - Lisa

    Lisa, 

    When exploring archeoastronomy it is advisable to consult multiple reputable resources to cross-reference data points.

    Check with NASA as well.  And, any other astronomy software you can access.

    What decides that Stellarium is accurate when differing from Starry Night?

    Regarding seconds, I do not understand the question.  Starry Night time includes seconds.  Please clarify.

    Thanks!
