Your Sun sign

Your Sun sign is the zodiac sign the Sun was passing through on your birthday. It is the best-known part of astrology and describes your core identity, your energy and the person you are growing into.

The full deep dive

What the Sun shows

In astrology the Sun stands for your centre: your sense of self, your vitality, your pride and purpose. Its sign describes the flavour of that core self. It is the part of you that shines when you feel most yourself.

How it is worked out

Over a year the Sun appears to travel through all twelve signs, spending about a month in each. The dates shift by a day or so from year to year, so if your birthday is on the change between two signs (a “cusp”), the exact time and year decide which sign you are. Starlight works this out precisely.

The twelve Sun signs

Aries 21 March to 19 April Fire
Taurus 20 April to 20 May Earth
Gemini 21 May to 20 June Air
Cancer 21 June to 22 July Water
Leo 23 July to 22 August Fire
Virgo 23 August to 22 September Earth
Libra 23 September to 22 October Air
Scorpio 23 October to 21 November Water
Sagittarius 22 November to 21 December Fire
Capricorn 22 December to 19 January Earth
Aquarius 20 January to 18 February Air
Pisces 19 February to 20 March Water

Cusps

People born on the day the Sun changes sign sometimes say they are “on the cusp” and feel like a blend. Astronomically you are always one sign or the other, but neighbouring planets in your chart may well bring in the next sign’s flavour too.
