Understanding the display

Each pillar contains a heavenly stem and an earthly branch. The Day Master is the day stem. Elements are shown for the stem and branch, and hidden stems are associated with the branch. Ten Gods describe relationships between other stems and the Day Master; they are traditional technical labels, not literal deities.

When time is unknown, this preview checks 00:00, 12:00, 23:00 and 23:59:59 on the entered date for the stated solar-term and day-boundary rules. The hour pillar remains unknown. The results remain subject to the time-zone and true-solar-time limitations above.
