Aloha lunarwind,
You will find different systems/masters using each.
Marie uses the lunar calendar because in her experience it appears to work out best in most situations.
She would however say that if your birth date is on that new year cusp and it changes depending on whether the solar/lunar calendar is used, check both numbers out for you. What personality traits seem to align better? Muscle test it.
Much Love,
Shawn
