Because time zone abbreviations are not universally unique standard identifiers, several three-letter acronyms are shared by multiple regions on opposite sides of the planet. Schedulers must exercise caution when using the following abbreviations:

• CST: Can designate Central Standard Time in North America (UTC-6:00), China Standard Time in East Asia (UTC+8:00), or Cuba Standard Time (UTC-5:00)—representing a massive 14-hour difference between Chicago and Beijing.
• BST: Can refer to British Summer Time in the United Kingdom (UTC+1:00) or Bangladesh Standard Time in South Asia (UTC+6:00)—a 5-hour difference.
• IST: Can represent India Standard Time (UTC+5:30), Israel Standard Time (UTC+2:00), or Irish Standard Time (UTC+1:00).
• AST: Can refer to Atlantic Standard Time in the Americas (UTC-4:00) or Arabia Standard Time in the Middle East (UTC+3:00)—a 7-hour discrepancy.

Best Practice: When coordinating cross-border meetings, always pair the acronym with its numerical UTC offset (e.g., CST (UTC-6)) or generate an automatic local-time invite using our Shareable Event Link Tool.
