Before we begin
Western Synastry reads from your birth details
Sign in and we'll keep them for you, so the next reading starts where this one leaves off.
Overlay two natal charts and see the aspects that form between each person's planets, plus how their elements and modes — cardinal, fixed, mutable — line up.
- Both dates of birth
- Both birth times — this fixes each person's Ascendant and houses
- Both birth places — longitude and timezone for each chart

Me needs a complete birth place (latitude and longitude) before Synastry can calculate the Ascendant and houses.
