Tips for UK and Canada (Toronto) teams
- Both places use daylight saving time, but in opposite seasons or on different dates, so the gap changes during the year. Check the dates above before booking recurring meetings.
- There's enough shared time for a daily meeting. Booking it in the middle of the window leaves room for follow-ups on both sides.
