Hello everybody,
I been hitting an issue for a while now that date commands return the
wrong month on day 31 of a month and my automations stops working on
correctly on these days.
root@sydney:~# date
Wed Aug 31 22:09:04 CEST 2022
root@sydney:~# date --date "1 month ago" +%Y-%m
2022-07
root@sydney:~# date --date "2 month ago" +%Y-%m
2022-07
root@sydney:~# date --date "3 month ago" +%Y-%m
2022-05
root@sydney:~# date --date "4 month ago" +%Y-%m
2022-05
root@sydney:~# date
Sat Dec 31 19:20:13 CET 2022
root@sydney:~# date --date '1 month ago' +%Y-%m
2022-12
$ date --version
date (GNU coreutils) 8.30

I would love to have this fixed if possible.
If I am using the wrong command I would love to be educated as well.
Should I use date --date "$(date +%Y-%m-01) -1 month" +%Y-%m instead...
Kind regards,
Jelle de Jong
