They're the same length on either side of the date of the equinox, which falls in March and September. In 2009 those dates were 3/20 and 9/22, respectively. Just count days on either side of those dates, to answer our question.
What ends up happening, is that the first 20 days of March will have roughly the same length of daylight as the 20 days AFTER the September equinox (i.e. 9/22 thru 10/11). Similarly, the first twenty days of September will have the quality of daylight shown for the first 20 days after the spring equinox (3/20 thru 4/9)
