When King Louis XVI of France was a child, an astrologer warned him to be on his guard on the 21st day of each month. Consequently, he never conducted any business on that date. Even so, on June 21, 1791, following the French Revolution, Louis, and his queen, Marie Antoinette, were arrested in Varennes while trying to flee France. Then on September 21, 1792, France abolished the monarchy, and finally on January 21, 1793, Louis was executed by guillotine. (From Ripley’s Believe It Or Not, Beyond the Bizarre)
