Aries rising
Aries rising means Aries was crossing the eastern horizon at the minute of your birth, so it is the sign people meet before they meet your Sun. It takes 51.3 minutes to rise at the latitude of London, which gives it 3.57% of ascendants there — 11th of the twelve — and makes Mars your chart ruler.
What Aries rising is read as
Aries rising arrives before it is introduced. The traditional reading is a fast walk, a direct look and a habit of answering the question that was asked rather than the one that was polite. People describe an Aries ascendant as confident on first meeting and impatient on second, and both descriptions come from the same thing: the mask has no waiting stage in it.
The gap between the mask and the person
Because the mask acts first, whatever the Sun is doing tends to arrive late in the conversation. A quiet sign behind an Aries ascendant is the classic mismatch — the person is read as pushy and experiences themselves as private.
Aries as a Sun sign is a different reading again, and the big three together are what most descriptions are actually built from.

How common a Aries ascendant is
Aries crosses the horizon in 51.3 minutes at 52°N — 3.57% of the day, 1× what Pisces takes there, and 11 of twelve. The reason the signs are uneven is on the calculator page.

The chart a Aries ascendant builds
With Aries first, the other three angles follow without a choice being made, and Mars becomes the chart ruler.
Whole-sign angles, as the tradition assigned them; a timed birth chart places the midheaven by degree and can move it a sign either way.

What Aries rising says about your birth hour
Given a Aries ascendant, your Sun sign fixes the hour — the method, and its margin, is on the calculator page.
If your birth time is approximate
Aries holds the horizon 51 minutes at a stretch at 52°N, so even half an hour of doubt can put you outside it. One sign either way is Pisces rising or Taurus rising — another ruler, another set of angles. The calculator returns every sign the recorded time allows; without a time at all, the moon sign is the placement that still holds.
Either side of it on the horizon: Pisces rising, Taurus rising and Libra rising.
