Expression: Week days, starting at 6am, every 15 minutes - repeat for 12 hours


I’m seeking a cron that can schedule running a job, monday-friday, starting at 6am, every 15th minute - for a duration of 12 hours.

The closest that I’ve got is this simple expression: */15 * * * 1-5

I’m missing out the “starting at 6am” and “for a duration of 12 hours”.

Is this possible? And/or is it possible to combine multiple cron expressions?

Thanks in advance


To my knowledge the only way to do it is to schedule same job but apply different id to it. That way same code base will be executed at different time. I have run in to the same limitation of hangfire.

Isn’t it 0/15 6-17 * * 1-5?
