I have just refreshed baklabel on PyPI and upped it from my local svn 
server to github [1]


The changes include resolving ambiguous dates across locales eg USA vs 
Australia 5/6/2023 being detected as May in USA and June in Australia on 
the assumption that the user knows what is required.

What is the use case?


However I have hit a problem with converting dates, the bash script
has:-

 dat=$(date --date "$1" +"%Y/%m/%d")

and this will accept almost anything reasonably sensible that can be
interpreted as a date, in particular it accepts things like "tomorrow",
"yesterday" and "next thursday".

Is there anything similar in Python or would I be better off simply
using os.system() to run date from the python program?

In particular,check out dateutil.parser.
parser — dateutil 2.8.2 documentation


parser


This module offers a generic date/time string parser which is able to parse
most known formats to represent a date and/or time.

This module attempts to be forgiving with regards to unlikely input
formats, returning a datetime object even for dates which are ambiguous. If
an element of a date/time stamp is omitted, the following rules are applied:

in the standard library, datetime

as an addon module, dateutil  (install as python-dateutil)

Don't know if either are exactly what you want, but do take a look.
