This question already has an answer here:
Genesis 1:14 says that all Appointed Times (מועדים) are determined by the Sun and the Moon Phases. For example, all Holy Meetings (מקרא קדש) in the 1st or 7th months fall on moon phases.
However, Leviticus 23:27 says that Yom Kippur is on the 10th which does not fall on any moon phase.
So which verse is correct? Genesis 1:14 or Leviticus 23:27?
