Eastern Daylight Time is one hour ahead of Central Standard Time. So 1:00 (1 a.m.) EDT will be 0:00 (midnight) in Central Standard Time.
The Eastern Time Zone of the western hemisphere is a time zone that falls mostly along the east coast of North America. This zone’s clock time is based on the mean solar time of the 75th meridian west of the Greenwich Observatory. The Eastern Standard Time (EST) is specifically used when observing standard time (winter). This is in comparison to the Eastern Daylight Time (EDT), which is used when observing daylight saving time (spring - autumn). Since 2002, the local time changes on the second Sunday in March at 02:00 EST to 03:00 EDT and returns on the first Sunday in November at 02:00 EDT to 01:00 EST. The Eastern Time Zone is used primarily in Canada but is also used in 16 states of North America. Quintana Roo in Mexico followed EST until 1998 and some countries in the Caribbean use it all year round.
The Central Time Zone is also used in North America and refers to national time zones which subtract six hours from UTC to observe standard time and subtract five hours to observe daylight saving or summer time. The standard time is based on the mean solar time of the 90th meridian west of the Greenwich Observatory. The American and Canadian zones that use Central Standard Time are observing standard time in the winter months and Central Daylight Time when observing daylight saving time in the spring, summer and autumn months. The summer time in Mexico is indicated as horario de verano (summer schedule). The standard clock time in the Central time zones is one hour ahead of the Mountain time zones, an hour behind the Eastern time zones and two hours ahead of the Pacific time zones.
