CST vs EST Comparison
An in-depth guide to the 1-hour time difference between Central Standard Time (UTC-6) and Eastern Standard Time (UTC-5), longitudinal meridians, and cross-regional meeting scheduling.
Understanding the 1-Hour Time Gap
The North American Central Time Zone (CST, UTC-6) and Eastern Time Zone (EST, UTC-5) sit adjacent to each other across the central and eastern regions of the United States and Canada. Because the Earth rotates 15 degrees per hour, the 15-degree longitudinal difference between the 90th meridian west (Central Time anchor) and the 75th meridian west (Eastern Time anchor) creates an exact 60-minute solar shift.
