Question 1

What information do I need to calculate my birth chart?

Accepted Answer

You need your exact birth date, birth time (ideally from your birth certificate), and birth location (city and country). The more precise your birth time, the more accurate your chart will be.

Question 2

How accurate is this free birth chart calculator?

Accepted Answer

Our calculator uses the Swiss Ephemeris, the same astronomical algorithms used by professional astrology software, providing planetary positions accurate to within 1 arc minute.

Question 3

What if I don't know my exact birth time?

Accepted Answer

You can use 12:00 noon as a default. Your Sun, Moon, and planet signs will still be accurate, but the Ascendant and house placements may not be precise. For exact results, check your birth certificate or hospital records.
