EST to CST Converter
Last updated: May 31, 2026
Written by Blake Boege
An EST to CST timezone converter maps time offsets between the Eastern and Central time zones, accounting for daylight saving transitions.
Convert Eastern Time (EST/EDT) to Central Time (CST/CDT). Check current time zones, offsets, and view the hourly conversion table.
Quick Answer
Convert Eastern Time (EST/EDT) to Central Time (CST/CDT). EST is 1 hour ahead of CST. Updated dynamically relative to live clocks.
Convert time from EST
Current Live Offset: CST is 1 hour behind EST.
Select any custom hour or date above to compute the corresponding time in CST.

How it works
To convert time from EDT (Eastern Standard Time (EST) / Eastern Daylight Time (EDT)) to CDT (Central Standard Time (CST) / Central Daylight Time (CDT)), calculate the offset difference between the two timezones.
Current Timezone Offset
smCDT is sm1 hoursm behind smEDT.
Calculation Rules
Formula: Time in CDT = Time in EDT - 1 hour
Current Time Offset between EST and CST
The current relationship between Eastern Standard Time (EST) / Eastern Daylight Time (EDT) and Central Standard Time (CST) / Central Daylight Time (CDT) is that smCDT is sm1 hoursm behind smEDT. The offsets dynamically update depending on whether Daylight Saving Time (DST) is active in the United States.
How to convert EST to CST
To convert any local time between these zones, find the offset difference and shift the hours accordingly. If you cross a midnight boundary, the calendar date will shift forward or backward by one day.
Why Times Differ Between Regions
Time zones are structured based on longitudinal divisions around the globe, with solar noon aligning roughly with 12:00 PM local time. Daylight saving policies cause offsets to shift.

Frequently asked questions
Currently, smsmCDT is sm1 hoursm behind smEDT. For example, when it is 12:00 PM in smEDT, it is sm11:00 smAM in smCDT.
No, both timezones observe Daylight Saving Time (DST) on the exact same schedule in the United States. Therefore, the time difference between smEDT and smCDT remains constant at sm1 hours throughout the year.
To convert smEDT to smCDT, you simply smsubtract sm1 hoursm smfrom the current smEDT time. For example, if it is 3:00 PM smEDT, you smsubtract sm1 hoursm to get sm2:00 PM in smCDT.
