Madison Beer and Justin Herbert were born in March, five calendar days apart: she on March 5, 1999, in Jericho, New York, and he on March 10, 1998, in Eugene, Oregon (Madison Beer, Justin Herbert). Both are Pisces Suns. The singer-songwriter and the Los Angeles Chargers quarterback announced their engagement on July 28, 2026 (PEOPLE; corroborated by HollywoodLife).
"Two Pisces" is where a Sun-sign compatibility score would stop. The calculated charts point somewhere else: their closest contacts aren't in Pisces at all. They're in the first few degrees of Aries.
How this was calculated
Both charts are date-only. Madison's catalogue profile stores a birth time, but it isn't used here. Justin doesn't have a profile in our catalogue, and no time is used for him either.
Each birthday was sampled 25 times in local time, every hour plus 23:59, with Lunara's central Swiss Ephemeris engine. Each contact between the two charts was then checked across all 625 pairings of those samples. These are sampled bounds, not a continuous proof. There are no houses, no Rising sign and no Moon contacts.
Orb convention: 8° for a conjunction between the Suns. For contacts between the charts, this article only highlights pairs that stay within 3½° at every pairing.
The Suns: close, but not the main event
- Madison: Sun at about 14–15° Pisces
- Justin: Sun at about 19½–20½° Pisces
That's a gap of about 4½–6½°, inside an 8° conjunction orb all day. It's real, but it's wide, and it's what being born a few days apart in March almost always gives you.
The observation: an early-Aries meeting point
Both charts put several planets near the start of Aries:
- Madison: Mercury at about 2–3° Aries, Jupiter at about 4½–5° Aries.
- Justin: Mercury at about 3½–5½° Aries, Mars at about 4½–5° Aries.
Laid side by side, that cluster produces the tightest contacts between the two charts:
- Her Jupiter on his Mars: 0–0.6° apart across all pairings.
- Her Jupiter on his Mercury: 0–1.2° apart.
- Her Mercury near his Mercury: about 1–3½° apart.
In astrology, Mercury is read as how someone thinks and talks, Mars as how they act, and Jupiter as encouragement and enlargement. Aries is read as direct, quick and first-to-move. A Jupiter–Mars contact between two charts is traditionally read as one person's optimism amplifying the other's drive. That's a symbolic description of how two placements meet. It's not a statement about how this couple talks, decides or behaves, and it predicts nothing about their marriage.
Where the charts differ
A Sun-sign score treats two Pisces as near-identical. The rest of these charts don't agree:
- Venus: Madison's is in Aries, about 14–15°. Justin's is in Aquarius, about 4½–5½°.
- Mars: Madison's is in Scorpio, about 11°. Justin's is in Aries, as above.
- Moon: Madison's stays in Libra all day. Justin's is in Leo for almost the whole day, moving into Virgo at about 23:35 local time, so strictly it's Leo or Virgo.
Different Venus signs, different Mars signs and different Moons. That's why "Pisces + Pisces" is a weak summary of either person, let alone of two people together.
How two charts defeat a Sun-sign score
A Sun-sign score uses one planet per person. A comparison of two real charts looks at all of them, so it can find contacts the Sun signs never mention, like these in early Aries. It also shows the differences the shared sign hides.
Neither approach can tell you whether a relationship will work. What a full comparison can do is give you a more specific starting point for a conversation than a single label.
A question for your own chart
If you and someone you care about share a Sun sign, ask a better question than "are we compatible?":
- Where do your Mercury, Venus and Mars sit, and do any of them land near the other person's planets?
You can explore Madison's chart in full at Madison Beer's natal chart. To compare two charts of your own choosing, use the synastry chart. If you'd like to see how a written relationship reading handles contacts like these, start with the sample relationship reading. If you and a willing partner want your own, there's an optional paid relationship reading. It's a set of prompts for conversation, not a verdict, and what's included and the price are shown before you buy.
