Okay... I can't just assume that the hours of daylight at midsummer and Christmas are different in Shrewsbury and Jerusalem for a Cadfael drabble, I've got to go mucking around on the net for more exact info...
But I'll admit to goggling at what I figured out.
For June 22:
Jerusalem, 14 hours 14 minutes between sunrise and sunset
Shrewsbury, 16 hours 52 minutes ditto.
For December 25:
Jerusalem, 10 hours 4 minutes from sun up to sundown
Shrewsbury, 7 hours, 40 minutes...
The sun isn't above the horizon for even eight hours! Granted the twilight is a lot longer in Shrewsbury, forty minutes at midwinter to Jerusalem's twenty minutes, but wow, that's a lot of hours of dark!
Now, considering that medieval clocks set the hours by sunrise and sunset, dividing day and night each into twelve hours, and the monks had to get up in the middle of the night for at least one service... *wanders off in a fit of geekishness*
...er... there may be a drabble, eventually. I've got to go research medieval church services now.
