Frequently Asked Questions

How do I know if I am a "real" Leo?

If you were born when the Sun was between 0°00' and 29°59' Leo (typically July 23 through August 22), you are an authentic astrological Leo. Your exact degree further reveals whether you belong to the Pure Solar 1st Decan, the Expansive Jupiterian 2nd Decan, or the Martian Warrior 3rd Decan.

What if I was born on July 22 or July 23?

Because the Earth’s orbit takes approximately 365.25 days, the Sun crosses the threshold from Cancer into Leo at a slightly different hour every year (usually between late July 22 and early July 23 UTC). If you were born on these dates, you are on the Cancer-Leo "Cusp of Oscillation" and carry both empathetic intuition and royal fire.

What if I was born on August 22 or August 23?

You fall on the Leo-Virgo "Cusp of Exposure". If your Sun is at 29° Leo, you are a final-degree Leo with Regulus star power and early Virgo discernment. If your Sun has crossed into 0° Virgo, you are technically a Virgo Sun with a powerful Leo energetic residue.

Can someone be a Leo without being born in Leo season?

Yes! While your Sun sign defines your conscious vitality, having your Moon, Ascendant (Rising sign), Venus, or Mars in Leo imparts unmistakable Leo traits: a golden heart, natural charisma, dramatic self-expression, and unyielding loyalty.
