Help with flow. Monthly backups not woking as expected

External nodes needed:

node-red-contrib-fan

node-red-contrib-fs-ops

Test button to test.

Given all context variables are set.
global.event_paths
(not sure if there is another.)

Description:
A file is constantly written to:
{{global.event_paths}}/AC_In.db

Every month it gets a bit on the big size.

So at 23:55 of the last day of the month, a pulse is sent in. (The empty link node)
I moves the file to {{global.event_paths}}/{{year}}/{{month}}+"_"+ filename
I hope I got that right.

So basically I have this structure:
event_path
(oh, I can't do *ASCII art. Leading spaces are deleted)
It make a directory with the name of YYYY
and the file is the month name_(file name)

It works every time I press the test button.

But every 1'st of the month when I look:
I have AC_In.db and _AC_In.db in the same directory.

Yes, I know this if for AC_Out. It is a test.

If you feel bored and wouldn't mind looking I would appreciate some help.

As I said: I press the test button. It works.
Left to the inject node injecting a pulse at 23:55 of the last day.... It doesn't.

After thought:
Yes, there is probably a better/easier way. For now please help me learn from this mistake.
I may look at optimising it - or what ever you may want to call it - later. But for the sake of the exercise please look at this and where it is failing rather than re-writing the whole thing.

Oh, the code for the inject node:

This is the flow.
