Before sunrise you will see
Two bright stars — planets they be.
The brightest one is Venus.
Outshining Jupiter’s light.
Catch both before they’re consumed

July 4, 1776: Wondering whether the USA is the only country to celebrate its independence on the anniversary of simply declaring it, rather than on the anniversary of winning it. In our case, the British surrender at Yorktown, Virginia: October 19, 1781.
