What is the midheaven (MC)?
Astrology, explained straight
The Midheaven — abbreviated MC, from the Latin Medium Coeli, 'middle of the sky' — is the highest point in your birth chart, sitting at the cusp of your 10th house. It marks your public role, your reputation, and the version of you the world sees when you're operating at your most visible.
The MC is calculated from your exact birth time and location — it's the degree of the zodiac that was at the very top of the sky the moment you were born. The sign it falls in colors how your ambition and public persona express themselves, and any planets near it get a megaphone in your career and reputation story.
Your sun sign tells you who you are; your MC tells you what you're here to be known for — those aren't always the same thing. It's the placement that shows up in how colleagues, bosses, and the public perceive you, and ignoring it means building a career without reading half the blueprint.
If you don't know your birth time, get it — no birth time means no MC, and the most career-relevant point in your chart just disappears.
