Today is the vernal equinox, when the day and night hours are approximately equal. The sun will rise at 7:03AM and set at 7:08PM. The days will continue to lengthen until the Summer Solstice, June 21st, at which time we'll have 14 hours and 59 minutes of daylight.
In case you're wondering why the day and night not exactly equal today (I did), you'll find the explanation on TimeandDate.com.
