Cron Expression for running a job at different intervals at different hours

Question

I want to schedule a job to run every 5 mins during morning (4-8)AM and evening (7-11)PM and rest of the day every 30 minutes, how can i write a cron expression for it?

I can do this by using two cron expressions for scheduling, but can i do the task using one expression?

Answer 1

The timings (or intensity) are different, so you need different expressions.

So something like the following is needed:

*/5 4-7,19-22 * * * your/command
*/30 0-3,8-18,23 * * * your/command

Answer 2

No, I believe you'll need 2 separate CRON expressions.
