Understanding Time Zones
The world is divided into 24 primary time zones, each roughly 15 degrees of longitude wide. However, political boundaries mean that actual time zone lines are irregular.

Daylight Saving Time Considerations
Daylight Saving Time (DST) adds another layer of complexity. Not all countries observe DST, and those that do may change clocks on different dates. For example, the US and Europe have different DST transition dates, temporarily changing the time difference between them. Time Zone Converter.
Best Practices for Global Scheduling
- Always specify the timezone when sharing meeting times (e.g., '3 PM EST' instead of just '3 PM').
- Use UTC as a reference for international communications to avoid ambiguity.
- Consider work hours in all participants' time zones. Meeting Planner.
- Account for DST transitions when scheduling recurring meetings, especially around March and November.
