If you know someone’s birthday but don’t know the exact birth time, are there any techniques one can use for trying to make an educated guess for when it might be? Would their first impression indicate their ascendant or their midheaven, i.e. public face?
Studying – I don’t rectify charts. That said, if I was going to do this I would probably forget first impressions. The physical appearance is probably the most reliable marker of the rising sign.
For example, Sagittarius or Jupiter rising (like me) almost always has an overbite. Moon or Cancer rising almost always has a round face, etc.
I would start there, and narrow things down to a rising sign or two or three. Then rotate the chart until the planets in the houses made sense.
Anyone else? How do you go about rectifying a chart?
