Sun
The Sun is what a person is moving toward rather than what they already are — the direction of a life. This is why sun-sign descriptions so often read as aspirational and slightly ahead of the reader: they describe a trajectory, not a current state.

In Your Chart
The Sun's house shows the area of life where you most need to count for something. A Sun expressing itself well simply feels like being yourself without having to explain it.

Direction, Not Description
The Sun is read as what a person is moving toward rather than what they already are. It describes the trajectory of a life — what somebody orients by and is working out over decades.
This is why sun sign profiles so often read as slightly ahead of the reader, describing someone a little more fully themselves than you feel on an ordinary Tuesday.
It also explains the common experience of a sun sign that seems almost right. It is answering a question about direction, and most people arrive looking for a description of their behaviour.
Why It Dominates Popular Astrology
The Sun's prominence is a publishing accident rather than a doctrinal position. Newspaper columns needed a system that worked from a birth date alone, because that is all a reader can supply in print.
The Sun is the only major placement a date reliably determines. So the layer that got mass distribution is the one that happens to be computable without a birth time, not the one that describes people most sharply.
In a full chart the Sun is one of ten factors. It is important, and it is not the whole reading.
In the Chart
The Sun's house shows the area of life where you most need to count for something — where recognition matters and where a lack of it is felt disproportionately.
A Sun expressing itself well feels like being yourself without having to explain it. A blocked Sun tends to show up as a persistent sense of not being seen accurately.
Aspects from Saturn are traditionally read as delay and eventual substance; from Jupiter as ease that can become excess. The Sun is rarely the difficult part of a chart on its own.
The Boundary Question
Sign boundaries are astronomical events rather than calendar dates, and they shift by up to a day between years because the tropical year is not a whole number of days.
Anyone born within about a day of a boundary genuinely needs it computed rather than looked up, and a great many sources will give them the neighbouring sign with complete confidence.
The Solar Key computes the Sun's actual position for your birth year, and says so when your date falls close enough that the year decided it.
