How to use it
- Pick your date of birth. Only the month and day matter; the year is ignored.
- Read your sun sign, the usual dates of that sign, its element and modality.
- If the note about the cusp appears, your birthday is the first or last day of the sign.
The twelve signs and their dates
Aries 21 March – 19 April · Taurus 20 April – 20 May · Gemini 21 May – 20 June · Cancer 21 June – 22 July · Leo 23 July – 22 August · Virgo 23 August – 22 September · Libra 23 September – 22 October · Scorpio 23 October – 21 November · Sagittarius 22 November – 21 December · Capricorn 22 December – 19 January · Aquarius 20 January – 18 February · Pisces 19 February – 20 March.
Elements repeat in order: fire (Aries, Leo, Sagittarius), earth (Taurus, Virgo, Capricorn), air (Gemini, Libra, Aquarius), water (Cancer, Scorpio, Pisces). Modalities: cardinal (Aries, Cancer, Libra, Capricorn), fixed (Taurus, Leo, Scorpio, Aquarius) and mutable (Gemini, Virgo, Sagittarius, Pisces).
Worked examples
15 May falls between 20 April and 20 May, so it is Taurus (earth, fixed). 21 March is the first day of Aries, and 20 March the last day of Pisces, so both are marked as a cusp.
About the dates
Printed ranges are a convention, not an exact astronomical fact. For a birth on a cusp, the exact moment the Sun changed sign in your birth year and your time zone decide the sign. Zodiac signs describe a tradition of astrology and are not scientific predictions.
