Why use this schedule
Mid-month jobs, such as payroll runs or the second half of a twice-monthly billing cycle. Paired with the 1st of the month it splits a month into two even halves.
- Mid-month payroll
- Twice-monthly reports (with the 1st)
- Mid-cycle reminders

Things to watch out for in Kubernetes
- If both day fields are set, the job runs when either matches. This is standard cron behaviour.
- A CronJob creates a new Job object each run. Set concurrencyPolicy and startingDeadlineSeconds so missed runs behave as you expect.
- Set spec.timeZone (Kubernetes 1.27+) to a name like Asia/Kolkata. Without it the schedule follows the controller's time zone, usually UTC.
The common mistake with this schedule
The 15th can be a weekend. Cron cannot shift to the next business day on its own; check in the job, or use Quartz 15W for the nearest weekday.
