Your Sun sign is the zodiac sign the Sun occupied at the moment of your birth. In Vedic astrology this is the sidereal Sun sign, calculated against the actual position of the stars, while the Western Sun sign you already know is tropical, tied to the seasons. Because the two systems differ by about 24 degrees (the ayanamsa), your Vedic Sun sign is often the previous sign to your Western one — which is why a Western Scorpio is frequently a Vedic Libra. The Sun represents your soul, ego, vitality, confidence and your bond with your father and authority. Knowing your true sidereal Sun sign is essential for accurate Vedic predictions and remedies.

Your date of birth (and time if known) — the Sun stays in one sign for about a month, so the date is usually enough.

Most people know their Western (tropical) Sun sign from newspapers and apps. But Vedic astrology uses the sidereal zodiac, measured against the fixed stars. Over centuries the two zodiacs have drifted about 24 degrees apart, a gap called the ayanamsa. This means that if you were born in the last week or so of a Western sign, your Vedic Sun sign is usually the sign before it. A Western Scorpio often becomes a Vedic Libra, a Western Leo a Vedic Cancer, and so on. For any genuine Vedic reading, your sidereal Sun sign is the one that matters.

A strong Sun brings confidence, vitality and success. You can strengthen it by offering water to the rising Sun (Surya Arghya) at dawn, especially on Sundays, chanting the Sun’s mantra "Om Ghrini Suryaya Namah", respecting your father and elders, and honouring authority. A ruby (Manik) can strengthen a weak Sun, but only after proper consultation — the wrong gemstone can do more harm than good.
