Understanding the CST to EST Time Conversion
What is CST?
Central Standard Time (CST) is a time zone used in parts of North America, including much of the central United States, central Canada, Mexico, and parts of the Caribbean. It is 6 hours behind Coordinated Universal Time (UTC-6:00).
What is EST?
Eastern Standard Time (EST) is a time zone used in eastern parts of North America, including the eastern United States, eastern Canada, and parts of the Caribbean. It is 5 hours behind Coordinated Universal Time (UTC-5:00).
Converting 10 AM CST to EST
When it's 10:00 AM in Central Standard Time (CST), it's 11:00 AM in Eastern Standard Time (EST). This is because EST is one hour ahead of CST. The simple formula is: CST time + 1 hour = EST time.
Daylight Saving Time
Both CST and EST observe Daylight Saving Time. During DST, CST becomes CDT (Central Daylight Time) and EST becomes EDT (Eastern Daylight Time). The one-hour difference remains constant throughout the year.
Major Cities in CST
Chicago, Dallas, Houston, Minneapolis, New Orleans, Mexico City, and Winnipeg are among the major cities that follow Central Time.
Major Cities in EST
New York, Washington D.C., Boston, Miami, Atlanta, Toronto, and Montreal are among the major cities that follow Eastern Time.

Tips for Working Across Time Zones
Schedule Meetings Wisely
When scheduling meetings between CST and EST, aim for mid-morning to early afternoon CST (late morning to mid-afternoon EST) for optimal productivity.
Specify the Time Zone
Always specify which time zone you're referring to when communicating times to avoid confusion.
Use 24-Hour Format
Consider using the 24-hour format to eliminate AM/PM confusion when working across time zones.
Utilize Time Zone Tools
Use digital calendars and time zone converters (like this one!) to ensure accurate scheduling.
