The pattern appears to be in ISO/"work" weeks 14, 2 hols, 14, 2 hols, 13/14, 7/8
hols/DST, to align the weeks with the years, like an ISO work year shifted a
fortnight later.
If anyone wants to play with the school term dates for years documented on the
site, they may be able to come up with a consistent relation to ISO weeks, that
should also be consistent with the DST dates.
Even if true, for a single case, it's unlikely anyone will extend the tz date
notation to support ISO week/day date relations, as that might encourage those
countries who use them widely to define *their* DST periods as ISO weeks, and
that could spread, as administrators buy calendars marked with ISO weeks ;^>

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
