Why Your Rising Sign Is Probably Wrong
Nine in ten horoscope sites compute your Ascendant from your birth date alone. That is impossible by definition — and the fix takes one extra field.
01
The four-minute problem
The Ascendant is the degree of the ecliptic rising over the eastern horizon at the exact moment you were born. It moves one degree roughly every four minutes, and the entire zodiac crosses it every 24 hours. A birth time off by ninety minutes is a different rising sign — often a different everything. Any calculator that asks only for a date is not computing your Ascendant; it is guessing one.
02
Where the guess comes from
The habit dates back to newspaper astrology: one sun sign per date range, mass-printed, free of computation. It survived the internet because it is easy. But the math has been public for centuries — given a date, a time, and a coordinate, the rising degree is a fixed triangle problem. There is no reason to guess in 2026, and we do not.
03
What we do instead
Alfalaki computes your Ascendant from three inputs — date, time, and location — using the same VSOP87 series observatories use. If you do not know your birth time, we tell you plainly that the Ascendant and houses are omitted, rather than inventing one. A chart with an honest gap is worth more than a complete-looking lie.
