Um, read Leviticus 23:1-3.  

And YHVH spoke unto Moses, saying,
Speak unto the children of Israel, and say unto them, Concerning the
feasts (mo'edim) of YHVH, which ye shall
proclaim to be holy convocations, even these are my
feasts. (mo'edim)
Six days shall work be done: but the seventh day is the sabbath of rest, a holy convocation; ye shall do no work
therein: it is the sabbath of YHVH in all your dwellings
.

If I'm reading this as it is written, YHVH calls the Sabbath one of His mo'edim TWICE in verse 2.  Mo'ed means set
feast or time appointed.  And if I can read
Genesis 1:14 and Psalm 104:19, the MOON regulates YHVH's calendar
appointments in time (calendar mo'edim).
10.  The Creator never calls the weekly Seventh-day Sabbath a mo’ed or one of the
Mo'edim.  This is a term used to describe the annual feasts.
