A reference for astrology, numerology and divination that shows its arithmetic and labels its sources — including where the tradition ends and the maths begins.
Most esoteric sites give you a paragraph and no way to check it. AstroHot was built the other way round: every reading is generated from a calculation, and the calculation is printed next to the result. If a page tells you your Sun sits at 18°42′ Leo, the sums that produced that figure are on the same screen.
That means you can disagree with us. A birth chart is arithmetic — positions of bodies at a moment in time — and arithmetic is verifiable. What those positions mean is tradition, and tradition is not verifiable. We keep the two apart and say which is which.
Solar longitude is computed from the mean longitude plus the equation of centre; the Moon from the synodic month of 29.530588 days measured against a known reference new moon. Sign ingress times are found by binary search on the longitude function, which is why our sign boundaries are given to the minute rather than as a fixed calendar date.
Where a page says something is rare or common — a Life Path distribution, the share of births falling under each sign, which arcana can never sit at the centre of a Destiny Matrix — that figure was produced by enumerating every date in the stated range, not quoted from another site. The range is always printed.
Interpretations are attributed to their actual origin — Golden Dawn correspondences of 1888 for the Tarot, the Chaldean and Pythagorean letter tables for numerology, published dream-content research where prevalence figures are given. Where schools disagree, we say so instead of picking one silently.
There is no known mechanism by which the position of a planet at your birth could determine your character, and no evidence that it does. We do not pretend otherwise, and we do not dress the material up with fake credentials or invented ancient pedigrees. The Destiny Matrix, for instance, was assembled in the 2010s — we say that on the page, even though it sells better without the sentence.
Nothing here is medical, legal, financial or psychological advice. See the disclaimer for the plain version.
AstroHot is free and requires no account. It is paid for by advertising. We do not sell readings, do not run a psychic hotline, and do not pass your birth date to anyone — it is used to render the page you requested and then discarded. The privacy policy sets that out formally.
If a calculation is wrong, we want to know — that is the one kind of error on a site like this that is genuinely fixable. Write to us via the contact page with the date you entered and the figure you expected, and we will check the working.
The fastest way to see what we mean is to run one and read the working.
