HOW ABOUT YOUR CHART CORRECTION?
A corrected chart is a chart with an estimated hour of birth based upon the correspondence between events in an individual's life, transits and progression. When there is no hour of birth available for you, you could give it a try to find a possible hour of birth. Personally, I have an offical hour of birth and my mother;s time (just 3 minutes later). I have tried to find the exact minute a few times and I ended with possible hours of birth between 12:25 and 12:45. The official time is in the middle:)!
AND THE CHART RATING ON ASTRODATABANK?
A lot of charts of VIP's are corrected or estimated charts. That is why the work of Astrodatabank to find the true hour of birth and mention the source or controversy is so valuable and appreciated.
For example the chart of Joan of Arc, that is a DD-rated chart. An AA-rated chart is one with birth certificate in hand (like Barack Obama's chart:). A DD-rated chart has a date that is not verified. Always check the rating to see if you can use the chart as a tool for understanding transits and progressions!
