I think I found the bug. The function split-string here lets date-string equal [2009-07-27 instead of 2009-07-27

You found a common error when splitting strings. Your function split-string is likely including the
square bracket character, "[" as part of the split value instead of recognizing it as a delimiter or
extraneous character.

You might consider adjusting your function to remove or ignore special characters like "[", "]"
during the split process, or, prior to calling split-string, you might sanitize your date-string by
removing all square brackets.

For example, whatever language you are using, you might do something like:
#+BEGIN_SRC python
* Python Example
date_string = date_string.replace("[", "").replace("]", "")
#+END_SRC
#+BEGIN_SRC javascript
// JavaScript Example
date_string = date_string.replace(/\[/g, "").replace(/\]/g, "");
#+END_SRC
This might solve your problem as it will ensure that when you run split-string, you are only working
with the plain date information.

This indeed would be a bug. The function ~split-string~ is supposed to break apart a string into
separate parts, but in this case, it's incorrectly keeping the opening bracket '[' as part of the
first string element.

The bug could be in the implementation of ~split-string~ function if it does not correctly handle
special characters like square brackets or could be due to not properly cleaning up your inputs
before processing them.

You might need to clean the ~date-string~ variable before passing it to ~split-string~. This
cleaning could involve removing unwanted characters like this opening bracket.

Depending on your programming language a simple fix could be like:

Python:
#+BEGIN_SRC python 
date_string = date_string.strip('[') 
#+END_SRC

Java:
#+BEGIN_SRC java
date_string = date_string.replace("[", "");
#+END_SRC

This will ensure, ~[~ does not form part of your ~date-string~. 

Remember to also check your ~split-string~ function if it should typically handle such cases. The
function may need to be adjusted to accommodate or exclude such special characters as needed.
