Week numbers for year 2022 are wrong
So memento counts July 24th to July 30th as Week 31 but its Week 30 of the year
Paul Schauble commented
There are multiple incompatible definitions of fiscal week around the world. Which one are you hoping to use? Perhaps someone can tell us which one Memento actually uses. See https://www.timeanddate.com/date/week-numbers.html
There is more than one way to number the weeks in a year.
