Jeffrey Leonard (born September 22, 1955) is an American former professional baseball left fielder. He played fourteen seasons in Major League Baseball (MLB) from 1977 to 1990 for the Los Angeles Dodgers, Houston Astros, San Francisco Giants, Milwaukee Brewers, and Seattle Mariners.
Jeffrey Leonard was born four day after September 18, 1955. 
It's correct because he was born on September 22, 1955, which is exactly four days after September 18, 1955 (18+4=22). I think it has difficulty comprehending the concept of time and numbers.
