For those who live in a far northern or southern region of the planet, this will not be news, but for the vast majority of people who do not, the idea that the sun will not set in the summer until what is traditionally viewed as ‘night’ and will rise far too early in the morning is very foreign.  Look at the chart below, showing sunrise and sunset times for Cardiff (which is in southern Wales) for June 2010.  Note that for the entire month, the sun rise varies by 7 minutes:  rising at 5:02 am, reaching 4:55 am in the middle of the month, and by the end of the month is again at 4:59 am.  Sunset varies by 13 minutes, peaking at a 16 hour, 38 minute ‘day’.
