Answered my own Question
Dates with hyphens YYYY-0MM-0DD can be treated as valid dates so if
maintained in this format no conversion is necessary.
I was using a YYYY/0MM/0DD format so I could use the Tree macro, but
instead I made a new macro called a hyphentree, now I am working on another
called a date tree to provide a clickable tree of all date named tiddlers.
Regards
Tony
