Is the MC the same as the 10th House Cusp?
In quadrant systems like Placidus, yes. In Whole Sign houses, the MC can fall in the 9th, 10th, or 11th house, but it remains the point of highest culmination.
Can I calculate this without birth time?
No. Like the Ascendant, the MC relies entirely on the Earth's rotation. An accurate birth time is mandatory.
What about polar latitudes?
Our engine handles high-latitude calculations where the MC/ASC relationship can become distorted, prioritizing astronomical correctness.
