Frequently asked questions
Which zodiac system does this calculator use?
It uses common Western tropical date ranges, not sidereal astrology or a calculated birth chart.
Why can another source show a different sign?
Boundary dates, timezones and zodiac systems can produce different results, especially near a transition date.
Does the calculator use birth time or birthplace?
No. It matches only the entered month and day to a general date range.
Is a horoscope scientifically validated?
No. This tool is for cultural and recreational interest, not scientific, medical or financial guidance.
Limitations
Astrology is cultural and recreational rather than scientific guidance, and boundary systems can vary.
