Free Moon Sign Calculator | Find Your Lunar Sign Online | Astraia
See your Moon sign from your birth date, optional time, and birth place. We highlight your Moon first and show your Sun and Rising alongside, plus a chart wheel when it’s available. Add your email if you’d like a personalized PDF about your Moon.
What this Moon sign calculator shows
- Your Moon sign—the zodiac sign the Moon occupied at your birth—with degree and house when the chart supports it.
- Your Sun and Rising (Ascendant) in a compact summary so you can see your “big three” at a glance.
- Western tropical zodiac—the same system as most Western birth chart tools.
- Optional birth time: if unknown, we use noon local time; the Moon sign is usually still correct, but double-check if you were born near a sign change.
- Optional: a personalized Moon-focused PDF by email when you request it.

Moon sign calculator FAQ
Is this Moon sign calculator free?
Yes. You can view everything on the page without signing up. Email is only for the optional PDF.
Is my Moon sign the same as my Sun sign?
Usually not. Your Sun sign is where the Sun was when you were born; your Moon sign is where the Moon was. They describe different parts of your chart.
Do I need my exact birth time for my Moon sign?
Often no—the Moon changes signs roughly every two days, so the date and place are usually enough. Near a sign change, birth time helps confirm.
Is this Vedic or sidereal?
No—this page uses the Western tropical zodiac, same as our main birth chart calculator.
Can I get my full birth chart too?
Yes. This page can email a Moon-focused PDF. For a PDF with equal emphasis on Sun, Moon, and Rising, use our full natal chart calculator.
Why do you still show Sun and Rising?
So you can see your big three together. The page is optimized for Moon sign searches, but the calculation is a full natal chart behind the scenes.
