Temporary closure (maintenance): http://www.gov.je/News/2021/Pages/LesQuennevaisSwimmingPoolTemporaryClosure.aspx

Though it's missing any opening_hours anyway, the details for adding a new OH rule:
▪︎“closed from Tuesday 24 August [2021] for one week”
▪︎“will re-open on Wednesday 1 September [2021].”
so, “[…]; 2021 Aug 24-31 closed”.

“sport=multi” could do with refinement, too.
