Sun
In a horoscope, your Sun sign is your basic identity, the role you keep coming back to. It is what most "What's your sign?" answers point at.
In classical astrology the Sun is the chart's identity-bearer — your core self, the role you instinctively step into. In modern usage, the Sun sign (the zodiac sign the Sun was in at your birth) is what people mean when they ask "what's your sign?" — and what every Sun-sign horoscope on the internet, including ours, is based on.
The Sun moves through one sign each month, so its position in any given chart is shared by everyone born in that month. That is the strength and the weakness of Sun-sign astrology at once: it captures something real about a broad slice of people, but it does not capture you specifically. For that you would need the full chart with rising sign and Moon.
In our daily forecasts the Sun is the anchor. AIstra writes for the twelve Sun signs because that is the level at which "today's astrology" stays meaningful without requiring birth data.
