Frequently Asked Questions

How do I run on the last day of the month instead? ▾
Standard cron has no last-day feature. In Quartz, use "L" in the day-of-month field: "0 0 0 L * ?". For standard cron, your script must check whether tomorrow is the 1st and exit if not.
Why does AWS use "? " for day-of-week in this expression? ▾
AWS EventBridge requires either day-of-month OR day-of-week to be "?" — the one you don't intend to use. Since we're specifying day-of-month=1, day-of-week must be "?".
