Free tools

By Andrey Tadevosyan · Published 4 September 2026

Eleven free tools for questions worth examining. Calculate a base rate, plan a concrete action, or keep an experience separate from your interpretation. Choose the tool that fits your question; entries stay in your browser.

• Observe and reflect Experience notebook Keep an experience, possible explanations and an optional prediction together. Return to the original wording when you review what happened.
• Name and date Numerology chart calculator All seven core numbers from a name and a birth date, computed under both letter tables in print, so you can see where they disagree.
• Birth date Life path calculator Your number under both standard methods, and how common it is across every calendar date since 1900.
• Birth date Personal year calculator This year’s number and the next nine laid out in a table, which is the whole cycle.
• Two dates Compatibility calculator Two life paths, how many couples share your pairing, and how often the verdict flips between methods.
• Glances a day Angel number calculator How often chance alone predicts you will catch 11:11 and its cousins.
• Odds and days Coincidence calculator Enter how unlikely a thing is per day and how long you watched. It tells you how surprised to be.
• Birth date Sidereal sign calculator The sign the Western chart gives you and the one the constellations give you, and why both are right.
• Odds and attempts Attempts calculator How much of “it attracted the outcome” is simply more attempts. Five versus twenty, with your own odds.
• Plan and timers The 1089 protocol One priority, zero assumption, eight minutes of process, nine of action. A number turned into a plan.
• Four answers Experiment designer Writes the preregistration for your own thirty days: criterion first, misses logged, decision rule fixed.

Start with a record or a question

The Experience notebook begins with what you noticed. You can add personal meaning, other explanations, and a prediction with a deadline. Original wording stays visible when you return. The notebook saves only when you choose to and exports JSON or text.

What a calculator can clarify

A number on its own is not information. If a calculator tells you that your life path is 7, you have learned something only if you also know what share of everyone else is a 7. It is one ninth. That single fact changes how the sentence lands, and it is the fact almost every numerology site leaves out, because the sentence lands better without it.

The probability tools put the assumptions next to the answer. The life path and compatibility tools enumerate every real calendar date from 1900 to 2025 in your browser when you press the button, which is 46,021 dates, and count. The angel number and coincidence tools work the odds forward from a rate you choose. Nothing is looked up, nothing is estimated, and you can download the underlying tables from the open data page and check them.

Two systems, shown side by side

Most of the numerology in print comes in at least two versions. A life path can be computed by summing every digit of the date at once, or by reducing the month, day and year first, and the two disagree for about one birthday in seven. A name can be scored on the Pythagorean table, which cycles the alphabet through 1 to 9, or on the Chaldean table, which assigns values by sound and has no 9 at all. A compatibility chart in one book contradicts the chart in the next.

A calculator that silently picks one system is telling you about the system, not about you. Where two are in common use, the tools here compute both and say so when they differ. That is the honest version, and it happens to be the more interesting one: watching your own number change when the method changes teaches more about what the number is than any reading can.

What these tools will not do

The tools do not tell you who you are, who you should be with, or what this year holds. They will not grade you. There is no score anywhere on this site and no database column to hold one. Where a number carries a traditional meaning, the tool names it as what the codebook assigns, not as a finding.

If you want to know whether any of it predicts anything about your own life, that is not a question a calculator can answer and it is not a matter of opinion either. It is a thirty-day question with a criterion written down in advance, and the free experiment on this site exists to run exactly that.

Privacy

Calculations and notebook entries stay in your browser. The notebook keeps one device copy only when you explicitly save it; JSON exports let you keep a collection. Other tool entries are not stored by the site. Once loaded, the tools work without a network connection. The privacy page describes the two third-party scripts the essays carry; neither one receives anything you type into a tool.
