For you ifyou don't know your birth time, or you know it only roughly: "in the morning", "around three", a time rounded to the hour.
You receivea written report with your most likely birth time and the range around it, how confident I am and why, and your chart drawn for the new time.

I'll needYour birth date and place, the window you were born in, and 8 to 12 dated events from your life.

What's Inside

  • Your most likely birth time, with the range around it
  • How confident I am, high, medium or low, and the reasons in plain words
  • The runner-up time, if there is one, and what would tell the two apart
  • What the new time changes: your rising sign and degree, your houses, your Lot of Fortune and your daemon
  • The events that confirmed it, one by one, and which technique pointed to each
  • Your chart wheel, drawn for the rectified time
  • A short note to keep with your birth details, so any astrologer you see works from the same time

What to Send Me

It all goes in the order form. The more exact the dates, the better the result.

  • Your birth date and place. The town or city is enough.
  • The window. The earliest and latest time you could have been born, and where that comes from: your mother's memory, a hospital shift, "it was still dark", "just after lunch". Even "the morning" helps.
  • 8 to 12 dated events. Turning points with a day, or at least a month and year: a marriage or divorce, children born, a parent's death, moving to another country, a job or business that started or ended, a serious accident or operation, a big win or loss.

Events that changed the direction of your life work best. Moods and long hard stretches without a clear date help much less.

How It's Done

  1. I map your window. I cast the chart for the start and end of your window and for every change of rising sign in between, and check whether the Sun was above or below the horizon. A day birth and a night birth follow different rules, so if your window crosses sunrise or sunset, that alone splits the candidates.
  2. A first estimate, the old way. Ptolemy gives a rule for correcting the rising degree from the New or Full Moon before birth (Tetrabiblos III.2). Hephaistio of Thebes tested it on a large number of charts and found it "satisfactory in nearly all cases" (Apotelesmatics II.2). I use it as a starting point, never as the answer.
  3. I test every candidate against your life. Each possible time gives a different rising sign and a different order of time lords. For every event, I check:
    • Annual profections: which house and planet ran that year. A marriage should fall in a year that wakes up partnership, a move in one that wakes up home or travel.
    • Zodiacal releasing from Fortune and Spirit (Vettius Valens, Anthology IV): whether the big turns of your life land on the changes of period it marks.
    • Saturn and Jupiter crossing the angles, and eclipses on them. The rising degree and the Midheaven move fastest with the time, so they tell the candidates apart best.
    • Solar returns for the years of your biggest events.
  4. The time that keeps explaining your life wins. I score each candidate event by event, narrow it to a range of minutes where the evidence allows, and write it up with the reasoning shown, the measured astronomy and my judgment kept clearly apart.

Rooted in Ptolemy's rule of the New or Full Moon before birth, Hephaistio of Thebes, the time lords of Vettius Valens, annual profections, solar returns and transits to the angles.

How Exact It Gets

With a window of a few hours and clear dated events, I can often narrow it to a range of 10 to 20 minutes. Sometimes the evidence only settles the rising sign. That is still the part that matters most: it fixes your houses, the planet that rules your chart, and your daemon and Fortune.

Astro-Databank, the best-known collection of birth data, rates every rectified time C, for caution. That is the honest status of any rectification, mine included. If you later find your real time on a birth certificate, use that one. More on this in what rectification is, and what it can't do.

Common Questions

How long does it take? Usually around 7 days from the day you order, sometimes faster. If one of your dates is unclear and it matters, I'll write to you before I finish.

What if I have no idea at all, not even morning or evening? Then the whole day is in play, with all twelve rising signs. It can still work if you have plenty of clearly dated events, but my confidence will be lower. Message me before you order and I'll tell you honestly whether it's worth doing.

My birth certificate says 8:00 exactly. Do I need this? Probably not. A rounded time is usually close enough. It's worth it only if your rising sign or a key planet sits near the edge of a sign, so ask me before you order.

Can an app or calculator find my birth time? No. A calculator can't recover a time from a date. Any tool that claims to does what I do here, testing times against events, only without a person weighing the evidence.

Can I use the new time for my other readings? Yes. Put it in the order form for any reading and say in the form that it's rectified, so I treat it as a best fit.

Can you rectify someone else's chart? Yes, with their window and their dated events. Please check they're happy for you to share their birth details.
