Jia Zi through Gui Hai — all sixty, written one at a time.
Personality · the marriage seat · life stage · void branches · markers · compatibility.
A BaZi chart takes the year, month, day and hour you were born and writes each as two characters — four pillars, eight characters. The pair for the day is your day pillar. The top character is you; the bottom character is the ground you stand on and the seat your partner occupies. It is the first pillar anyone reads.
The day pillar is fixed by the date you were born, so it comes out the same whether or not you know the hour. (The one case worth checking is a birth after about 11:30pm, where the date rolls over.) Only the hour pillar is lost without a birth time — the day pillar is not.
Your day master is the character that stands for you in the chart. Pillars sharing a day master share a base; the branch underneath changes the grain.

Two people born on the same day can read very differently once the year, month and hour are in.
A full reading computes all four pillars and writes them up - about 5 minutes, delivered as a report you keep.
A day pillar is one of four. Two people with the same day pillar can read very differently once the year, month and hour are in. This dictionary sets out the grain each day pillar points along; an accurate reading takes the whole chart.
