Ascendant
Point of the ecliptic rising above the horizon at birth. Marks the boundary of the first house and depends on time to the minute.
What it means
Ascendant — the degree of the ecliptic that rose above the horizon at the moment of birth. It defines the start of the first house, and thus the whole house system, and is therefore the most time‑sensitive point in the chart: it moves by one degree every four minutes and completes a full circle in a day.

- HouseOne of the twelve sectors of the chart, representing an area of life: the first – how a person is seen, the seventh – partnership. The house boundaries depend on the time and place of birth, so without a known time the houses are not constructed.
- House systemThe rule by which the chart is divided into houses. MIRA calculates using Placidus, and beyond the polar circle, where this method loses meaning, switches to Porphyry and indicates which system is applied.
- UTCCoordinated universal time to which the birth moment is converted. Calculations are performed in it, not in local time.
