Readers will recall our sporadic and profoundly frivolous interest in pulp astrology, predicated on nothing more than the fact that often people who seem quite similar share birthdays.

Indira Gandhi and Zeenat Aman, both indisputably powerful women, were born on November 19; Aishwarya Rai and Nita Ambani share their birthday on November 1; Rupert Murdoch and Samir Jain (and ahem, yours truly) were born on March 11 and so on and so forth.
