Every year the National Committee on Pay Equity publicizes its bogus feminist holiday known as Equal Pay Day to bring public attention to a completely spurious, apples-to-oranges comparison of incomes by gender.

According to the NCPE, Equal Pay Day will fall on Tuesday, April 4 this year, based on a 20 percent unadjusted difference in median annual earnings for women and men in 2015 (most recent data available). That data point controls for absolutely nothing relevant that would explain income differences like hours worked, marital status, number of children, education, occupation and the number of years of continuous uninterrupted job experience.
