Why the date matters
The Day Master follows the 60-day stem-branch cycle, not the weekday or the animal assigned to your birth year. A correct calendar conversion is required.
Every BaZi pillar has a Heavenly Stem above an Earthly Branch. In the Day Pillar, the stem is your Day Master and the branch is your Spouse Palace. The other seven chart characters are interpreted in relation to this center.
