Scheduling Tips
- Schedule at 4:00-5:00 PM GMT / 8:00-9:00 AM PST for the sweet spot where both teams are alert and available.
- UK managers can batch async reviews and decisions in the morning (9:00 AM-12:00 PM GMT) and save the afternoon for live calls with the West Coast.
- Watch the DST transition weeks in March and October — set calendar reminders to verify recurring meeting times have not shifted.
