Cron Expression to schedule a job

问题

我想在特定的时间表上运行我的代码。因此,我需要一个Cron表达式来安排每个月的第12天的工作,但不包括星期六和星期日(即仅在工作日安排工作的第12天)。是否可以安排这样的任务?可以有人帮助找到解决方案吗?

英文:

I would like to run my code on specific schedule.So i need a cron expression to schedule a job for every 12th day of the month by excluding saturdays and sundays (means scheduling a job only on weekdays for every 12th day of the month). Is this possible to schedule ??

Can someone help for the solution to get me out here

答案1

得分: 1

是的,这是很容易实现的。

5 4 */12 * 1-5

"如果每个月的第12天是星期一到星期五,那么在每天的04:05执行任务。"

编辑:我误解了问题,抱歉。我认为只使用CRON字符串本身不可能实现这一点。

作为一个简单的解决方案建议:只需将任务安排在每个工作日执行(例如5 4 * * 1-5),然后在作业开始时检查是否是每个月的第12个工作日工作日。如果是,启动您的业务流程,如果不是,就退出。

英文:

Yes it's easily possible.

5 4 */12 * 1-5

> “At 04:05 on every 12th day-of-month if it's on every day-of-week from Monday through Friday.”

Edit: I misunderstood the question, sorry. I don't think that's possible only with the CRON string itself.

As an easy solution proposal: just schedule the task itself every business day (e.g. 5 4 * * 1-5) and then check at the start of the job if it is the 12th business day of the month. If so, start your business process and if not just exit.
