About This Schedule
Standard cron doesn't have a built-in "last day of month" keyword. The expression 0 0 28-31 * * runs on days 28, 29, 30, and 31 — but that runs multiple times at month-end for months with 30 or 31 days.
For true last-day-only behavior, you need to combine cron with a date check in your script:
0 0 28-31 * * [ "$(date -d tomorrow +\%d)" = "01" ] && /path/to/your/scriptSome cron implementations support the L modifier: 0 0 L * * means "last day of the month." This is available in Quartz, Spring, and some extended cron libraries, but not in standard Unix cron.
