Meeting planning notes
London is represented by the IANA zone Europe/London. Tokyo is represented by Asia/Tokyo. These names avoid ambiguous abbreviations and handle daylight saving time when the browser has current time zone rules.
For recurring meetings, check dates around March, April, October, and November because many regions shift daylight saving time on different weekends.
