The short answer: your minute of birth decides whether a reading is about you or about someone else. In a few minutes the sky shifts, and the chart shifts with it. A four-minute difference moves the dates in a forecast by about a year. So we don’t read a chart until the time is established: first we find the minute, then comes the reading.
How it started
Octant began with a search for a birth time. We did our first readings for people we knew, and with almost every one of them the same thing came up: they didn’t know their exact birth time. The birth certificate said one thing and mom remembered another, and some people had neither a record nor a memory. So the first job in every reading became finding the minute to build the chart on. We still start there.
That’s why there’s no form for your birth date and time on this site: we ask for them once we’re in touch, establish the time first, and only then read the chart.
What the moment of birth is
Birth isn’t a single instant. In astrology, the moment of birth is the first breath: the baby starts breathing on their own, and that’s the point the chart is built on. Hospital staff write down what someone managed to notice, often a little after the fact, once the baby is breathing and someone has a free hand. The time gets rounded, most often to the nearest five or fifteen minutes, sometimes to the nearest half hour. With a long labor, the gap between the recorded time and the actual moment of birth can be bigger.
A time relatives remember is one step further removed. “Born in the morning” covers several hours, and “around eight” is about an hour. Memories can shift over decades, too.
So for us, a recorded time is a good starting point, not the answer. We check it the same way we check a time relatives remember. There’s just usually less work.
What one degree changes
The sky turns one degree every four minutes or so, and in the calculation of a forecast one degree is about one year of life. So a four-minute difference in the birth time moves the dates in a forecast by about a year.
In a few minutes the sky shifts, and the chart shifts with it: someone born ten minutes earlier has a different chart. The full arithmetic is in the article “Why four minutes can move your forecast by a year.”
A birth time check is part of every reading we do. Check whether your case is a good fit
How the minute is found
The method works backward, from your life to the minute rather than from the record to your life. It needs dated events that have already happened: moves, marriages and breakups, the birth of children, big changes at work, surgeries. The month and year are enough. Each event is a test: with the right time it fits the calculation, with the wrong time it doesn’t. One event rules out very little; ten can rule out a lot.
There’s a second layer too: everyday questions. How you dress, how organized your paperwork is, how you treat your car, what the atmosphere was like in the home you grew up in. Times a few minutes apart describe appearance, manner, and childhood differently, and habits work like a fingerprint that shows which of the options is yours. So answer honestly: an answer shaped by how you’d like to be seen sends the search off course.
The system works through the options, and the astrologer decides which one is yours. For each event in your life, the document shows how it confirms the minute we found. It lists the other times that were considered and says why each one was ruled out. It also says how confident we are in the result.
Astrologers call this work rectification. We call it finding your birth time.
When the minute can’t be found, and when it’s hard to find
In some cases, a search won’t give an answer. Before you pay, we tell you whether we can take your case.
- You know only the date and the part of the day: morning, afternoon, evening, or night. Or only the date. We don’t take cases like these. Unless you know your time to within three or four hours, any minute we found would be made up. Instead, we’ll offer a personality reading without a birth time: it covers your character and strengths, but without tying them to areas of life like work or home, and without dates.
- Children and teenagers. The search needs dated events from adult life, and a child doesn’t have them yet.
- An adult with no dated events at all: there’s nothing to go on. If you can date only a few events, we look at your situation case by case: sometimes everyday answers and two or three dates are enough, sometimes not.
- For now, we don’t take cases for people born near or above the Arctic Circle, for example in northern Alaska or northern Scandinavia, because there a small error in the time makes a large error in the chart. A personality reading without a birth time is still possible in that case.
- Your time falls in a window of three to four hours, or you can date fewer than five events. We consider a case like this individually.
What this means for you
If you know your time exactly, we still check it, and then build the reading on it. If you know it roughly, it can be pinned down from events in your life. That’s where the work starts, and the Find your birth time page explains what the search needs and what you get. If there’s no reference point at all, we’ll tell you so.
You can see where you stand in a minute: a few questions on the home page show whether we can take your case. Short answers to questions about birth time are on our FAQ page.
