FAQ
Why do some weeks cross the year boundary?
ISO weeks use the Thursday rule to pick week 1, so week 1 can start in late December of the previous year, and the last week can spill into January of the next.
What does the "Wk" number mean?
It is the ISO 8601 week number of the row (Monday is the first day of the week).
