Which dates can be Leo

Since 1920 the sun has entered Leo on 22 July or 23 July, and left it for Virgo on 22 August, 23 August or 24 August (UTC). On those dates the sign depends on the year, and in a crossing year on the hour; each date's page gives every year.

In the tradition

In Western astrological tradition, Leo is classed as a fixed fire sign. Fixed signs are the signs that hold the middle of a season, traditionally read as sustainers, and fire signs are traditionally associated with energy, initiative and self-assertion. Its ruling planet in that tradition is the Sun.

These are associations reported from tradition, not claims about anyone born under the sign.
