Narrow down your birth time using life events

Over a day the planets barely move, but the angles of the chart — the Ascendant and the Midheaven — go all the way round the circle. So if you know the dates of events, you can cut out the times of day at which those events don’t hit anything in the chart. That’s how rectification works: an astrologer does it by hand, going through charts, and we go through every minute.

What this calculation can and can’t do

It won’t name your minute of birth. We tested the method on seven charts where the time is known from documents: the true time lands, on average, in the top 12% of the ranking — so the day narrows down to a few hours, but not to the minute.

Worse, on made-up dates the calculation also finds a nice peak — weaker than a real one, but it finds it. So we always calculate the background too: we plug in random dates and see whether your result is stronger. If it isn’t, we’ll say so instead of showing you a convincing picture.

Whose time are we looking for

What you remember about the time

The narrower the window, the more accurate the result. If you have no idea at all, leave “No idea at all” and the calculation will cover the whole day.

Life events — eight fields, fill in as many as you rememberEight isn’t a requirement — it’s the margin at which the calculation becomes reliable; we’ll calculate from three. Sharp events with an exact date work best. At least six months should pass between any two: closer ones check the same thing and inflate the result. Other people’s events work too: your parents’ divorce, a grandmother’s death, your family moving when you were a child.

Tick the box — the calculation won’t start without it.

The dates you enter aren’t stored on the server: the calculation runs in memory and isn’t written to a database or to logs, and they don’t go into the payment either. After payment, a PDF with the reading and these dates will arrive by email at the address from your order; we keep a copy of the email for no longer than 30 days. So you don’t have to type everything again, they’re saved in your browser — on this device and only for you. You can erase them with the “Forget the data I entered” button at the bottom of any page.

Events filled in: 0. There’s nothing to search dates with yet — you need at least three: with one or two, a fitting time can be found for any chart. You can still calculate: we’ll show what we know for sure — what in your chart depends on the time at all.
