June 21, 2013 - 1:04 a.m. (Eastern Time Zone) - Summer Solstice

from Old Farmer's Almanac -- www.almanac.com/ The Summer Solstice ____________________________ Each year, the timing of the solstice depends on when the Sun reaches its farthest point north of the equator. This occurs annually on June 20 or June 21 in North America, depending on your time zone. The word solstice is from the Latin solstitium, from sol (sun) and stitium (to stop), reflecting the fact that the Sun appears to stop at this time (and again at the winter solstice).
