Born on June 30
Sun in Cancer.
Your Sun sign
Anyone born on June 30 has the Sun in Cancer. A Cancer Sun is learning to care without disappearing into it. The work of the sign is protection that does not become control, and a home that includes you.
The decan
June 30 falls in the first decan of Cancer — roughly 0° to 10° of the sign. The first decan is the sign at its most undiluted. Everything the sign is known for shows up here with the least interference — for better and for worse, this is the purest expression of it. Here that sub-ruler is Cancer itself, ruled by the Moon: a double dose rather than a blend.
The Egyptian decan
Long before the Greeks divided the sky into twelve, Egyptian astronomers cut the year into thirty-six decans of about ten days, each marked by the star that rose with the dawn. June 30 belongs to Tms-n-Khentet, decan 18 of thirty-six, whose rising star is Zubenelgenubi and whose traditional quality is the rising flood. This is a separate tradition from the western zodiac above, not a translation of it — the two were built from different sky-watching and they disagree in places.
The deity for this date
The Egyptian deity paired with this date is Anubis (Inpu) — Earth element, sacred animal the Jackal. Guardians of the threshold between worlds, Anubis souls navigate the shadowed places with calm authority. They are deeply loyal, profoundly honest, and possess an uncanny ability to judge character. They guide others through their darkest hours with steady, unwavering presence.
The day number
As a date, June 30 reduces to a 3 — expression, humour, and the need for a creative outlet that other people actually see. This is the day number rather than your full Life Path, which needs the month and year as well — but it is the part of the calculation your birthday alone decides.
What a birth date cannot tell you
One thing worth being clear about: a birth date on its own fixes your Sun sign and very little else. Your Moon sign changes every two and a half days, and your Rising sign changes roughly every two hours and depends on where you were born. Two people who share June 30 can have almost nothing else in common chart-wise.
Two people share this birthday and almost nothing else
Your Moon sign needs a time, your Rising sign needs a time and a place. Six questions, no card.

What zodiac sign is June 30?
June 30 is Cancer. The Sun is comfortably inside Cancer on this date in every year, so unlike the eleven cusp dates there is no ambiguity here.
Which decan is June 30?
June 30 falls in the first decan of Cancer, the 0–10° band, sub-ruled by the Moon. Decans divide each sign into three ten-degree sections, which is how two people of the same sign can read quite differently.
Does my birthday tell you my Moon sign?
No. The Moon crosses a sign every two and a half days, so a date alone cannot fix it — you need at least the year, and usually the time. Zodaiya's Moon sign calculator will tell you honestly when your date is not enough to settle it.
What is special about being born on June 30?
Astrologically: the Sun's position, the decan it falls in, and the Egyptian deity Anubis traditionally paired with this part of the year. What it does not fix is the rest of your chart, which is where most of the personal detail actually lives.
