About AstroHot

A reference for astrology, numerology and divination that shows its arithmetic and labels its sources — including where the tradition ends and the math begins.

About AstroHot — Who Writes This and How It Is Calculated

What this site does differently

Most esoteric sites give you a paragraph and no way to check it. AstroHot was built the other way around: 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.

Who builds it

AstroHot is built by Denis Kataev, a software developer rather than an astrologer. He wrote the calculators and the checks behind them; the interpretations come from the published sources named on each page.

Where the numbers come from

The formulas themselves — solar longitude, lunar phase, the ascendant, the timing of sign changes to the minute — are published in full on the methodology page, together with the accuracy we claim for each and the sources behind every traditional meaning. The short version:

Astronomical positions

In the chart calculators, the Sun, the Moon and the planets for 1900 to 2030 come from NASA JPL’s DE440 ephemeris, accurate to about an arcsecond; outside those years, from JPL orbital elements corrected for precession. The dates and times of events — stations, sign changes, phases and eclipses from 1900 to 2050 — come from NASA JPL’s DE440 ephemeris, checked against Swiss Ephemeris, which is why our sign boundaries are given to the minute rather than as a fixed calendar date.

Statistical claims

Where a page says something is rare or common — a Life Path distribution, or the arcana that never sit at the center of a Destiny Matrix — that figure was produced by enumerating every date in the stated range, not quoted from another site. Births by day and sign come from US Social Security data for 2000–2014. The range is always printed.

Traditional meanings

Interpretations are attributed to their actual origin — Golden Dawn correspondences of 1888 for 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.

The dashed line is today. A figure is only as good as the years behind it, so every page that quotes one of these numbers prints its range next to it.

What we will not claim

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.

How the site is funded

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.

Where AstroHot publishes

The same readings go out as short videos and cards every day. These are the only accounts that belong to us — anything else using the name is not ours.

  • YouTube — @Astrohotcom, daily short readings
  • Instagram — @astrohotcom, readings as reels
  • TikTok — @astrohotcom, daily short videos
  • Facebook — Astrohot — Horoscope & Astrology, reels and cards
  • Pinterest — @astrohotcom, boards by section

Corrections

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.

How we choose sources, check every statement of fact and handle corrections is set out in full in our editorial policy.

The fastest way to see what we mean is to run one and read the working.
