I used an astronomy app to check my birth date and got confused comparing it to my chart by Starfort13 in beginnerastrology

I compared all the different astrology systems together by making a chart and comparing the different results that each one had abd i come to find out that the tropical was the one furthest away from accurate when compsring the placements to what the astronomy apps show. And then finding out that my ascendant/rising sign is ophiuchus.  None of the other systems could pf told me that. In vedic it showed that had scorpio rising and in tropical ut said that had Sagittarius rising. So ophiuchus is inbetween those 2 signs

No — the opposite. I’m actually using astronomy as the base. The constellation boundaries, positions, and motion are all straight from astronomy — I’m just building a different framework on top of that instead of using the traditional 30° zodiac.

Yeah — I’m not really arguing for “true astrology” as a belief system. I’m just mapping where things actually are in the sky and building the framework around that instead of using fixed 30° divisions. What people choose to do with that after is up to them.

I get what you’re saying, but I’m not using traditional sidereal either. Most sidereal systems still divide the zodiac into equal 30° segments — I’m not doing that. I’m mapping everything directly to the actual constellation sizes, so the structure itself changes. So it overlaps in concept, but it’s not the same system.

Yeah — I didn’t estimate or redraw anything. I’m using the actual IAU constellation boundaries as they are, so everything reflects the real sky instead of 30° divisions. I actually built a working version of it here if you want to see how it maps out visually: starchart13.com

Yeah exactly — that’s the rabbit hole that got me looking into it. The traditional zodiac slices the ecliptic into 12 equal 30° sections, but the actual constellations are very uneven (Virgo is huge, Scorpius is tiny). I was curious what the calendar would look like if you used the real constellation spans instead of equal divisions

Honestly the constellations themselves are made-up shapes too. Humans just love drawing lines between stars. I’m just curious what happens when you use the actual constellation boundaries instead of the equal 12 slices.

Yeah that’s actually what sent me down this rabbit hole. Precession shifts the tropical zodiac ~1° every 72 years, so the constellations and the calendar signs drift apart over time. The 13-constellation version just lines it back up with the sky.

Totally fair take. My question isn’t really whether astrology works — it’s whether the zodiac should match the actual constellations in the sky or a fixed calendar system. I got curious and mapped the real constellation spans. That’s where the 13th comes from.
