| "2nd last Sunday" seems a little obscure though. Probably just a
| coincidence it fits two years running.
For October there have been (or will have been, after this next one)
three of them, which is more like a pattern, particularly if it happens
again next year. For summer time ending this will be only the
second time, so basing forward estimates on that is more problematic.
The "2nd last" thing isn't as weird as it sounds, though we don't yet
have enough data to know if that's how they're picking dates (deliberately
os just because some other factor leads to the same result).
Another plausible possibility is "Sun>=19" (the last Sunday that results
in a full week after the shift) (in a 31 day month of course).
Assuming the basic pattern continues, we'll know which of those it is
(assuming it is either) when the dates for 2015 are announced (the
2014-2015 dates for the Jan date, and the 2015-2016 dates for Oct).
