Welcome to the forum.
One small correction which i would like to specify to your last post.6th 8th and 12th houses from ascendant are called as dushanas in which the natural malefic planets gives out positive results and benific planets give negative results / neutral. And 1 4 7 10 are kendra stanas where benific gives good and malefic planets give bad results and 5 9 and 11 moola trikona or sextile house gives the same results as later.
And most of the time if ones birth time is not accurate then best practice is to analyse by moon position as moon is connected to our mind and if you dont know the exact date, however month is known then its good to analyse from the sun position who is atma karka or our soul.
