Scheduling Tips
- Start meetings at 7:00-8:00 AM PST / 3:00-4:00 PM GMT. This is early for the West Coast but the only reliable overlap window.
- During the March and October DST transition weeks, verify your recurring meeting times — they may shift by 1 hour unexpectedly.
- For async collaboration, have UK team members post end-of-day updates by 5:00 PM GMT so the PST team can pick up at 9:00 AM their time.
