If there's an equal pay day, shouldn't there also be an equal work day? [View all]

The President proclaimed April 9th as Equal Pay Day, to reflect the BLS data for average weekly earnings which report a raw gender wage gap($854 weekly wage for men vs $691 for women) of 23.5% for 2012. I'm not entirely sure where they come up with April 9th. 23.5% of 365 days is about 86 days and the 86th day of the year is March 27th, so perhaps someone can explain this to me.

Also from the BLS there's a raw gender work gap of 40%(3.74 average hours per day for men vs 2.67 for women). 60% of 365 is 212 days. This means that by August 7th, men will have worked as much as women will all year.

Is my math correct here?
