Replace Y with o for expected year.
Definitly subtle, misleading and brain damaged.

There is no bug here. This is correct as per the ISO-8601 Date spec. The first
week of the year is the week that contains the first Thursday. And weeks always
start on Mondays. That means the first day of the first week is not always in
the
same calendar year as the first Thursday. Please read the ISO-8601 spec for
more
details.
