Pro Tips
DST Warning: Time differences change during DST transitions! EST to PST is normally 3 hours, but can temporarily be 2 or 4 hours during transition weeks.
Best Practice: Always specify timezone in meeting invites (e.g., "2:00 PM EST" not just "2:00 PM")
For Developers: Store all timestamps in UTC, convert to local time only for display
Recurring Events: Use timezone-aware calendar apps. A "9 AM Monday call" should stay at 9 AM local time even through DST changes.
