I am attempting to see if or how the two phenomenon of a 28 day, 13 moon calendar system and the equinoxes, along with solstices can work in conjunction to each other.
I am seeking individuals in the field of astro physics that I may pose a couple of basic questions?
Allow me to reword the question.
Of me investigation for better understanding. I noted that the 28 day 13 moon cycle creates a negative day (losses a day) in relation to the solar equinoxes, solstices cycle. Is this so?

W.D,
This is not a matter of astrophysics - merely celestial mechanics.
Broadly, the orbital parameters of the Moon (ie, its period) are uncoupled from those of the Earth.
The moon has orbited the Earth at quite different distances from the Earth in the past - the present situation is purely circumstantial.
Calendars are basically conventions, usually made on "compromises" based on astronomical events (Earth rotation, Moon-Earth orbit, Earth-Sun orbit) that are mostly uncorrelated, varying over long timescales, and not integer multiples of each other.
Thank you for your input Adrien. I very much appreciate it.
I understand exactly what you are saying. However, I am seeking greater understanding of the relation of the aspects within my question that I need not take the next 6 years of my life learning astronomy to gain the understanding i need to move forward.

W.D.,
The equinoxes, by definition, are equally spaced in the solar year.
Since the Moon's period is not coupled to the Earth's, then there is no reason to expect a 28 day 13 moon cycle to be related in any way to the solar year.
For all intents and purposes, the length of a year and the length of the moon's orbit are random numbers and there is zero connection between them. As James said, there is absolutely no reason the two cycles should be synchronized in any way.
Please do not say "creates a negative day" or "loses a day". You are just inventing confusion that shouldn't be there. You just have two cycles (moon orbit, Earth orbit) that are not integer multiples. This is not hard to understand, and you do not need 6 years of astrophysics to understand this. What you need to understand is simply that the length of Earth's orbit and the length of the moon's orbit are basically random values that come out of planet formation.
I very much understand all inputs and thank each and every one for your interest. I have found a resolution to my quandary. It is not an answer to my question. However, it has resolved my issue. Again. Thank you all for you thoughts and input.
