Monthly cron jobs typically run on the 1st of each month using `0 0 1 * *`. You can change the day-of-month field to run on any specific day, like the 15th with `0 0 15 * *`.

Frequently Asked Questions

The cron expression for monthly jobs on the 1st is 0 0 1 * *. This runs at midnight on the 1st day of every month. Change the 1 to run on a different day, like 0 0 15 * * for the 15th.
There's no direct cron syntax for 'last day'. Common solutions: use 0 0 28-31 * * and check the date in your script, or use a tool that supports L for last day like some cloud schedulers.
Standard cron doesn't directly support this. Use 0 0 1-7 * 1 to run every Monday in the first week, then check if it's the first Monday in your script.
They're equivalent. @monthly is a shorthand supported by some cron implementations, meaning 'once a month at midnight on the 1st'. Both run at 00:00 on the 1st of each month.
