Sarah (above chart) gave birth to a Son on 5 Nov 2005 during the dasa of JU-RA-JU-ME. Combust Mercury, tightly conjunct 5th lord Sun in 11th house of "Gains", occupies nakshatra (constellation) of antardasa lord Rahu who in turn occupies nakshatra of sookshmar lord Mercury - a powerful exchange! The two luminaries (Sun and Moon) also sit in Rahu's nakshatra and they, along with Mercury, occupy Taurus saptamsha...divisional chart for children. In transit chart (left), Rahu, in sign of Jupiter again occupies nakshatra of Mercury. Shaun (below chart) was, at this time, running sookshmar dasa of Saturn who (alone) is inimically placed in 8th bhava in sign of Scorpio. Saturn also occupies Scorpio saptamsha... There should be no doubt that, although many (not only twins) may seemingly have the same horoscope, no two have the same destiny. When astrologers come up against this situation (often) their first reaction is to make alterations to the birth time in order to explain the (apparently) unexplainable differences. Of course there's always the possibility of incorrect birth data; but in situations where T.O.B. is confirmed to be correct we do need to look deeply into the dasas/transits to find the answer.
