I would just like to comment that when we are not sure of our time of birth and especially our date of birth, any analysis is bound to be flawed.
This isn't true for me. Any chart is worth analysis until such information comes to light that that would cause us to adjust it. If everything that happens in any moment in time, has the
qualities of that moment in time, the precept that all astrology is based upon and cannot survive without, then surely if we are given a chart, whatever the time, then it has significant information to yield to that person
at that time. Everything happens for a reason, that's what astrology is all about. I once used a chart for myself for the wrong time, willfully in fact, and I found out all sorts about myself as a result.
Refer to the thread 'Tampering with the Natal', in the natal section. I would provide a link but I don't know how. I am sure that there are other relevant threads about this, perhaps AM could direct you to them?
until a rectfication is done and the chart is as accurate as possible
When rectifying a chart is it a case of determining what is
accurate or what is
significant? Rectification of a chart is dependent upon what is most significant according to observations, whether or not it is 'accurate' or not according to the mathematics of clock time, would be impossible to ever ascertain.
If a chart is rectified, the surely there ought to some sort of time to which the rectified chart can be compared and contrasted, otherwise, where is the control factor in the experiment?
I dont even read a chart if the day is right and the time is not known within at least half an hour or so.
This is a shame. Lately I have been thinking that it is very worthwhile, when looking at a persons chart, to first just look at a solar chart, and thouroughly consider the placement of the planets and the aspects between them, even before going on to consider the ascendant and houses. This gives an outside-in approach, observing the major themes before zeroing in on the finer details.
It is a terribly disheartening experience for anyone interested in astrology to be told that the cosmos has singled them out to never be able to learn any insight upon themselves, because they do not know the precise time that they were born. Also, without a thorough as possible consideration of the chart without a birth time, then how can it be determined what area of this chart is the most appropriate place to put the ascendant in relation to who that person is and the nature of their life, and a control birth time against which this can be compared?
Another thing that I consider is, even if a person does not know the time of birth, then they often know the general part fo the day they were born in. There are four pivotal moments in a twenty four hour period, dawn, noon, dusk and midnight. Many work with a noon chart for unknown birth time, but I find this quite arbitrary, it can get finer than this. I know my birth time, but sunset was the first of the four pivotal moments to occur after my birth, so I consider the sunset chart to be a secondary chart for me, and this is the secondary chart also of everyone who was born at the same location as me between noon and sunset, it isn't as fine tuned as a specific birth time, but it is certainly better than nothing. I would only use the noon chart had I been born before sunrise and noon, sunrise had I been born between midnight and dawn.
I will need to explain this further, but this method is a theory I have, not only for birth times that are not known, but I think that such charts make interesting comparison to the chart for the known birth time.
