Good to know

L means "last day of the month". It is supported by CronEngine, Quartz and several other schedulers, but not by a classic Linux crontab or GitHub Actions.
In a crontab, run on the 28th to 31st and let the command check whether tomorrow is the 1st; see the snippet below.

Typical uses: Closing the books, month-end exports, final billing runs.

Copy and paste

crontab -e Crontab

# A classic crontab has no L. Run on the 28th to 31st and let the
# command check that tomorrow is the 1st:
0 23 28-31 * * [ "$(date -d tomorrow +\%d)" = "01" ] && /path/to/script.sh

GitHub Actions does not support L in a schedule.

routes/console.php Laravel

Schedule::command('your:command')->lastDayOfMonth('23:00');

Variations

0 0 1 * *	The first day of the month →
0 9 28 * *	The 28th of every month, which exists in every month
