I never knew you could do this with date(1). The man page punts to the
info pages (yuck).
I think that "next month" adds the length of the current month to the
time. This is a 31-day month, we're quite late in it, so this hops
over all of February.
$ date
Tue 30 Jan 2024 06:46:05 PM EST
$ date -d'this month'
Tue 30 Jan 2024 06:46:10 PM EST
$ date -d'next month'
Fri 01 Mar 2024 06:46:17 PM EST
What you want to do is go back to the first of the month (all modern months
have a first) and then leap ahead a month.
$ date --date="$(date +%Y-%m-01) next month"
Thu 01 Feb 2024 12:00:00 AM EST
$ date --date="$(date +%Y-%m-01) next month" +%m
02
The phony natural language that date accepts is a hazard.
