A note on August 20 birthdays

Between 26.3 and 28.6 degrees of Leo sits day 29 of the sign's 31. Mars sub-rules this late stretch, named in the triplicity system of decans as Leo's third decan, a sub-rulership the tradition ties to drive and to friction. Fixed and fire together mark Leo, read as a wish to hold firm while giving warmth without holding back. This run of Leo ends on August 22, one day before Virgo begins.
