4. Why Exact Birth Time Matters on Boundary Dates
Because the Earth takes approximately 365.25 days to orbit the Sun, the exact hour the Sun crosses into 0° Leo moves by several hours each year.
If you were born on July 22 or July 23, or on August 22 or August 23, checking a standard calendar is not enough. Calculating a precise birth chart with your time and city of birth ensures accurate placement of your Sun and neighboring planets.
Frequently Asked Questions About Leo Dates
What are the exact dates for Leo season?
In standard Western tropical astrology, Leo season runs from July 23 through August 22. Anyone born during this period generally has their Sun in Leo.
When does Leo season start and end each year?
Leo season starts on or around July 23 when the Sun enters 0° Leo and ends around August 22 when the Sun moves into Virgo. Exact entry times vary by up to 24 hours depending on leap years.
What if I was born on July 22, July 23, August 22, or August 23?
These are boundary dates (cusps). Because the Sun moves into Leo at a precise minute on those days, calculating your exact birth time and birth location with an astrological chart is necessary to confirm whether your Sun is in Cancer, Leo, or Virgo.
What is a Decan and how does it relate to Leo dates?
The 30-degree span of Leo is divided into three 10-degree segments called Decans. Each 10-day birthday window is ruled by a different sub-planet (Sun, Jupiter, or Mars), giving your Leo personality distinct traits.
Can you have traits of two signs if born on a cusp?
While your Sun is technically in only one sign at the exact moment of birth, being born near a sign boundary often means inner planets (like Mercury or Venus) may reside in the neighboring sign, creating a blend of characteristics.
Does the Leo date range ever change in sidereal vs tropical astrology?
Yes. Tropical astrology (used here) bases Leo dates on Northern Hemisphere seasons (approx. July 23 – Aug 22). Sidereal astrology bases dates on visible constellation alignment (approx. August 16 – September 16).
