I did read the links very thoroughly, but there are a lot of things that can be conflicting.
like:
Moon Void of Course
The Void of Course Moon indicates nothing to worry about or nothing will happen. If you begin a project during this time, it may not succeed or ever develop; decisions made may never be acted upon. Disturbing news heard at this time may not be worth worrying about. This is a good time to gather information while detaching from the outcome. The void period ends when the moon enters the next sign.
The moon will be VOC 5 times between Dec. 16-24 including
on the 16th & 24th
... That coupled with the days where the moon will be in unfavorable zodiac signs will leave 3 days (17th, 22nd & 23rd) when hair cutting will achieve length.
Is this correct or am I making this complicated?
