Understanding Time Zones & DST

The world is divided into 24 primary time zones, each representing approximately 15 degrees of longitude. However, political boundaries, daylight saving time (DST), and historical decisions have created over 400 distinct time zones, including half-hour and quarter-hour offsets.

Daylight Saving Time (DST) Awareness

Region	DST Practice	Typical Change
North America	Most regions observe	March & November
Europe	EU observes (under review)	March & October
Australia	Some states only	October & April
Asia (most)	Does not observe	N/A
Africa (most)	Does not observe	N/A

Meeting Planning Best Practices

Avoid time zone confusion: Always specify timezone when scheduling (e.g., "3 PM EST" not just "3 PM").
Check DST transitions: Before and after DST changes, time differences shift by 1 hour. Verify dates carefully.
Find overlap hours: For US-Europe meetings: 9-11 AM EST works (afternoon in Europe). For US-Asia: early morning or late evening required.
Use 24-hour format: Reduces AM/PM confusion (e.g., 15:00 instead of 3:00 PM).
Consider working hours: Avoid scheduling meetings outside 9 AM - 6 PM local time unless necessary.

Time Zone Abbreviations

Common abbreviations like EST, PST, GMT, CET can be ambiguous. For example, "CST" could mean Central Standard Time (US), China Standard Time, or Cuba Standard Time. Always use full timezone names (e.g., "America/New_York") or specify UTC offset (e.g., "UTC-5") for clarity.
