A .net 7.0 maui app for calculating when all YHWH appointed times, including the weekly sabbath, is based upon the sun and the moon.
Genesis 1:14 And God [Elohim] said, Let there be LIGHTS [SUN and MOON] in the firmament of the heaven to DIVIDE the DAY FROM the NIGHT; and let them be for signs, and for SEASONS [MOED: appointed times/meetings], and for DAYS, and YEARS:
Genesis 1:16 And God [Elohim] made TWO GREAT LIGHTS; the GREATER LIGHT [SUN] to rule [dominate] the day, and the LESSER LIGHT [MOON] to rule [dominate] the night: He made the stars also [stars rule nothing, but they do teach the Gospel see Mazzaroth].
SabbathsThe day starts at sunrise, the moonth starts the sunrise after the dark conjunction, the year starts at the moonth after the spring equinox.
