I was premature in posting that. I still need to dig through a bunch of links and update them. I also need to reverse engineer that, once it’s working, so that I can use a spreadsheet in future years to quickly generate the monthly calendars.
The problem that I ran into which initiated this is that Obsidian does not currently handle the creation of new files from relative (broken) links. I get errors like “file names can’t end in a period” and “that folder already exists”. So I need to convert all of the relative paths to absolute paths, at least until the underlying bug(s) are fixed.
