Sorry, I should have mentioned, it needs to be a macro. https://tiddlywiki.com/#Macros%20in%20WikiText
At the top of your tiddler: \define my-macro() <$set name=pattern value="201909(0[1-9]|1[0-4])"> <$list filter="[regexp:created<pattern>]"> </$list> </$set> \end Then, somewhere lower down (below all other macros if you have more than one) ... <<my-macro>> You can rename my-macro to anything that suits you: date-thing, if you want. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
