Without a birth time we calculate the planets for noon; the Moon may be a sign off and houses/rising are skipped.

Frequently asked questions

What is a birth chart?

A birth chart (natal chart) is a map of where the Sun, Moon and planets were in the zodiac at the exact moment and place you were born. Astrologers read it to describe personality, emotional needs and relationship style.

Do I need my exact birth time?

For the Sun and planets, no. For your rising sign (Ascendant), houses and an exact Moon position you need the time — the rising sign changes roughly every two hours. Your birth certificate or a parent may know it.

What are the big three in astrology?

Your Sun sign (core identity), Moon sign (emotional needs) and Rising sign (how others first experience you). Together they give a much fuller picture than the Sun sign alone.

Which planets matter most for love?

Venus shows what you find attractive and how you show affection, Mars shows desire and how you pursue, and the Moon shows what you need to feel safe. Comparing these between two charts is called synastry.
