Get folder containing automator script

The path to the bash script would be $0, but what I was looking for is how the bash script could learn the location of the Automator script, which would be in a different location. There would be one bash script in a central location and possibly multiple Automator scripts placed in the folders where I want date-named folders to be created. HOWEVER, further research resulted in a pure AppleScript solution, which allows double-clicking on an AppleScript saved-as app to create the desired folders.

The actual AppleScript follows. I welcome any suggestions to improve on this novice effort (thank-you, Google!), which contains items that I don't quite understand.

tell application "Finder"

set {year:y, month:mon, day:d} to (current date)

set ys to y as string

set ms to mon * 1 as string

if the length of ms is 1 then set ms to "0" & ms

set ds to d as string

set fname to ys & "-" & ms & "-" & ds

set dname to container of (path to me) as alias

make new folder at folder dname with properties {name:fname}

end tell

Wow, thanx! This gives me a new appreciation for what Automator can do. I think my AppleScript solution will work for now.
