Three things most free charts get wrong

The time zone your city actually used

Clocks have not always followed today’s rules: summer time began and ended on different dates, and some places changed time zone altogether. Solstaria looks up the offset in force on your birth date, in your birth city.

No ascendant when the time is unknown

Houses and the rising sign move roughly a degree every four minutes. Without a birth time they cannot be known, so we leave them out rather than print a guess you would take seriously.

Compatibility as five readings, not one number

A single percentage tells you nothing you can act on. Two charts get compared across attraction, conversation, daily life, values and friction, and each one is explained.
