Currently observing EST â Eastern Standard Time. Observes EST â Eastern Standard Time part of the year, but not currently. Currently has same time zone offset as EST (UTC -5) but different time zone name. Eastern Standard Time (EST) is 5 hours behind Coordinated Universal Time.

The Eastern zone is one hour ahead of the Central zone. If it's 5:00 P.M in the CST zone, then it is 6:00 P.M in the EST zone. Always add one hour to the Central time to convert to the Eastern one. Both of these locations observe Daylight Saving Time, therefore there is a period of each year from March until November where the clocks are moved forward an hour.
