Difference Between EST and EDT Explained Simply
EST and EDT represent the same physical geographical region at different times of the year! During standard time (November to March), the clock is set to EST (UTC-5). In the spring (second Sunday in March), clocks "spring forward" by one hour to EDT (UTC-4) to capture more evening sunlight.
Daylight Saving Time (DST) Transitions
