About CDT to EDT Conversion

Last updated: April 2026

Converting time between CST and EST requires understanding their time zone offsets and any daylight saving time adjustments. CST (CDT) operates at UTC-5, while EST (EDT) is set to UTC-4. This means EST is 1 hour ahead CST. For example, when it's 3:09 AM CDT on May 21, 2026, it's 4:09 AM EDT in EST. Both America/Chicago and America/New_York observes daylight saving time, switching between CST (UTC-6) and CDT (UTC-5). Keep this in mind when converting times, especially during the spring and fall transition periods. Use this converter to quickly find the equivalent time in EST for any time in CST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
