Written by Blake Boege · Founder, Calculator Answers

A CST to EST timezone converter maps time offsets between the Central and Eastern time zones, accounting for daylight saving transitions.

Convert Central Time (CST/CDT) to Eastern Time (EST/EDT). Check current time zones, offsets, and view the hourly conversion table.

Quick Answer

Convert Central Time (CST/CDT) to Eastern Time (EST/EDT). CST is 1 hour behind EST. Updated dynamically relative to live clocks.

How it works

To convert time from CDT (Central Standard Time (CST) / Central Daylight Time (CDT)) to EDT (Eastern Standard Time (EST) / Eastern Daylight Time (EDT)), calculate the offset difference between the two timezones.

Current Timezone Offset

EDT is 1 hour ahead of CDT.

Calculation Rules

Formula: Time in EDT = Time in CDT + 1 hour

Current Time Offset between CST and EST

The current relationship between Central Standard Time (CST) / Central Daylight Time (CDT) and Eastern Standard Time (EST) / Eastern Daylight Time (EDT) is that EDT is 1 hour ahead of CDT. The offsets dynamically update depending on whether Daylight Saving Time (DST) is active in the United States.

How to convert CST to EST

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, EDT is 1 hour ahead of CDT. For example, when it is 12:00 PM in CDT, it is 1:00 PM in EDT.

No, both timezones observe Daylight Saving Time (DST) on the exact same schedule in the United States. Therefore, the time difference between CDT and EDT remains constant at 1 hours throughout the year.

To convert CDT to EDT, you simply add 1 hour to the current CDT time. For example, if it is 3:00 PM CDT, you add 1 hour to get 4:00 PM in EDT.
