This has only been cross-checked with the official source from 2010 onwards.
Jersey has the same public holidays as the United Kingdom (England Subdivision)
- plus an extra day on 9 May, to mark Liberation Day (ignoring special holidays
like the Corn Riots Anniversary in 2021).
If a bank holiday is on a sunday, a substitute weekday becomes a bank holiday,
normally the following Monday. From 2004 onwards this also applies to saturday.
