Just got back from Japan last night and am catching up on work and emails – as promised I’ll be posting replies to the questions I received. Here is the first one:

Q: “I have the same birthday as Leonardo DaVinci…My question is, recently another astrologer mentioned that DaVinci was a Taurus; however, I am an Aries. Is he a Taurus because of the progression of time, the centuries between us, or some other reason?”

(note: I’m presuming this person was born on April 15th.)

A: Da Vinci’s birth date is April 15th of 1452, but in Florentine Time (which started the ‘new day’ at sunset.) By our reckoning he was born on the evening of April 14th (‘three hours into the night’ according to the biography).

Then we need to account for the difference between Julian Calendar (which was used at that time) and Gregorian Calendar which we use now. At 1452 the difference is 9 days, so this finally gives us April 23, 1452 as the birth data of Da Vinci that astrologers use – which is Taurus.

Technical, but interesting!
