A correction of the example given for a week date in TiddlyWiki is that the template should use the wYYYY token for the ISO week-numbering year, not YYYY, since weeks may cross the traditional year boundary with some days of the week falling outside the year the week belongs to. It is a bit surprising that the final element of the week day number is missing when the other parts of the ISO standard are supported.
