    Description, as the server wrote it
    How much of a region's school holidays two vacation accounts cover, and which weeks stay open. School holidays run to about 60 working days a year while a vacation account holds 25 to 30 days, so a care day always costs exactly one vacation day and a joint family holiday costs two and covers one. Answers "can we cover the school holidays" for parents.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
