Today's day pillar is 庚辰 (geng chen), a yang Metal day in the sixty-day cycle. The month pillar is 甲辰 (jia chen), governed by the term 清明 (qingming).
The day master is the heavenly stem of the day pillar you were born on, and in a BaZi chart it stands for you.
日主 (ri zhu), sometimes 日元 (ri yuan), is the single character a whole reading is organised around. Everything else in a chart is described by how it relates to that stem: what feeds it, what it controls, what controls it. Someone born on a 丙 (bing) day has a yang Fire day master, and that is what people mean when they say they are a Fire person in this tradition.
It is worth being exact about the difference between that and this page. Today's day stem is today's, not yours. It only becomes a day master for the people who happen to have been born on this date.
Finding your own means having a birth date, and, if you were born late in the evening, a birth time as well, because of where the day boundary falls for birth charts.
