Born on March 30
Sun in Aries.
Your Sun sign
Anyone born on March 30 has the Sun in Aries. An Aries Sun is becoming someone who starts things and holds their ground. The work of the sign is courage without recklessness — learning that going first is a strength and going alone is a habit.
The decan
March 30 falls in the second decan of Aries — roughly 10° to 20° of the sign. The second decan blends the sign with the next member of its own element, which softens the edges and adds a second register. People born here are often told they "do not seem like a typical" version of their sign. The sub-ruling sign is Leo, ruled by the Sun, which adds warm and generous to the Aries base.
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. March 30 belongs to Sah, decan 9 of thirty-six, whose rising star is Orion (Sah) and whose traditional quality is celestial navigation. 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 Isis (Aset) — Water element, sacred animal the Kite bird. The most magical of all signs, Isis children are gifted with deep intuition and an almost supernatural ability to perceive hidden truths. They are devoted, passionate, and fiercely protective. Their love is legendary, capable of reassembling what the world has torn apart.
The day number
As a date, March 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 March 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 March 30?
March 30 is Aries. The Sun is comfortably inside Aries on this date in every year, so unlike the eleven cusp dates there is no ambiguity here.
Which decan is March 30?
March 30 falls in the second decan of Aries, the 10–20° band, sub-ruled by the Sun. 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 March 30?
Astrologically: the Sun's position, the decan it falls in, and the Egyptian deity Isis 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.
