Aquarius, a fixed air sign is on my 7th cusp, ruled by Saturn in Leo in 12.
This pairing works well because the air sign constantly breathes life, by way of ideas and imagination, into the fire sign's plans and aspirations.
People born between May 21 and June 21 are included in the mutable air sign of Gemini.
An Air sign (Libra, Gemini and Aquarius) can rationalize just about anything.
An air sign needs to analyze things and although it can have deep emotions, especially when the moon sign is in a fire sign, it will be more mental than emotional throughout life.
