Each study here starts from a sourced birth time and says how good that source is. Every planet, date and period comes from the same engine as our free kundli, checked against our live tools. Then we test the chart against dated public events in the person's life, with a rule fixed in advance, and say plainly when the events cannot confirm the birth time.
These are astrological studies for education and interest. They use only public, sourced facts, are not linked to or endorsed by the people they describe, and make no forecast about health, legal matters or private life. Each study is also written in Hindi.
