What the calculator shows

  • Six placements

    Your Sun, Venus and Moon signs and theirs, calculated from each birth date and city.

  • An honest note when a sign is uncertain

    Without a birth time, the sky is read at local noon. If the Sun, Venus or the Moon changed sign that day, both signs are shown and marked, and adding the birth time settles it.

  • Placements, not a verdict

    There is no score. LoveSigns focuses on the patterns behind a connection, with space for your own understanding.

Your Sun signs, or your birth charts?

Your Sun Sign Compatibility starts from your Sun sign and theirs and offers a free reflection on how they may meet. This calculator starts from birth details instead, and shows where the Sun, Venus and the Moon were for each of you.
