Fire signs: Aries, Leo, Sagittarius
Fire is associated with initiative, enthusiasm and expression. Aries starts with direct action; Leo sustains creative expression; Sagittarius looks for exploration and meaning.
Elements are symbolic categories in Western astrology. They do not measure physical composition or establish personality scientifically.
| Sign | Typical dates | Modality | Ruler |
|---|---|---|---|
| Aries | Mar 21 – Apr 19 | Cardinal | Mars |
| Leo | Jul 23 – Aug 22 | Fixed | Sun |
| Sagittarius | Nov 22 – Dec 21 | Mutable | Jupiter |
One element, three modalities
Each element contains one cardinal sign (initiating), one fixed sign (sustaining) and one mutable sign (adapting). Aries is cardinal; Leo is fixed; Sagittarius is mutable. This is how the tradition distinguishes signs that share an element.
Does sharing an element mean compatibility?
The three fire signs are 120° apart in the zodiac: a trine by sign. Astrology traditionally associates that geometry with ease, but a Sun-sign pairing cannot predict a relationship. Compare the actual birth charts with the synastry calculator or browse the compatibility chart.
Is my whole chart fire?
A Sun sign describes one placement. Your Moon, Ascendant and planets may be in other elements. The birth chart calculator shows those placements individually.
