What is EDT?
EDT stands for Eastern Daylight Time. Its offset from UTC is UTC-4, 4 hours behind UTC.
EDT is the summer time of the eastern United States and Canada, four hours behind UTC.
In winter these places go back to EST (UTC-5). People often write EST all year, but in summer the right name is EDT.
