¹ These places observe daylight saving time in May, June and July. Bonus points if you knew there was a blue moon this/next/next-next month. Super extra bonus points if you remember the astronomical definition of obliquity. Get Out Of My Head if, when you see "Greenwich", you think "sandwich" . . . . . . . . . (or "sammich").
