For example, for the built-in Journal tag, I would like to create a property called Day of the week, which would take a value of Monday, Tuesday, Wednesday, etc. Since the Journal’s page title is already a date (defined by the default Logseq settings for date format), it seems it would be possible to use a formula to extract the day of the week from the date. Is that possible in Logseq?
Having used Obsidian previously, something similar was possible using the Obsidian plugin Templater.
