An ephemeris calculates sky positions according to an astronomical model. An astrology reading then attaches a symbolic interpretation. These are different claims and should be presented separately.
Understand the method
A computed longitude can be checked against another ephemeris. A statement about personality, luck or a future relationship is not made scientifically valid simply because an accurate longitude appears beside it.
Use the information carefully
Use the tools for entertainment and reflection. Do not infer another person's private beliefs, feelings, health or future from a birth date or a card. Avoid important decisions based solely on these outputs.
Why explain uncertainty on a free calculator?
Clear limits let you understand the result. Unknown birth time, time-zone ambiguity and a sign boundary are reasons to narrow the claim rather than display false precision.
