I have a program that requires my audio files to have their release date in YYYY-MM-DD format in their year tag in order to sort them. I do not care about the actual dates but I need to set this value for 140 files. Is there a way to essentially count up (or down) the days starting from a specific date?

Example: I'd start with 2014-01-01 and would want to increment this for the other files. File 2 would have 2014-01-02, file 3 2014-01-03 and so on

I'd usually do something like this programmatically but the library I usually use assumes that the year tag is always an int.

You could use an action of the type "Format value" for that field and as  
Format string: `2014-01-$num(%_counter%,2)`  
which sets a 2-digit incremental number.  
It does not care about valid dates.

Nice, that worked. I just selected 30 each time and changed the month value. Much faster than setting every single one by hand. Thanks!
