# How to Calculate Your Rising and Moon Sign: A Beginner's Guide
Most people know their sun sign, the zodiac placement determined by birth date alone. But astrology offers two other key placements that shape personality and self-perception: your rising sign and moon sign.

If you lack your exact birth time, some calculators allow you to estimate or use noon as a placeholder for moon sign calculation. However, rising sign calculation specifically requires precise birth time since it shifts roughly every two hours as Earth rotates.
