EDT and EST are not the same. EST stands for Eastern Standard Time, observed during the fall and winter months, and is 5 hours behind UTC. EDT, or Eastern Daylight Time, is used in the spring and summer, 4 hours behind UTC. The one-hour difference results from Daylight Saving Time, designed to make better use of daylight during the evening in the warmer months.
