Can I know how to read the Cron below


schedule: '*/5 * * * * * *' #

Can I know I want it scheduled in certain timing such as 10 am, 2:30 pm, 4 pm and 7 pm. Can this be done?

I also saw we have
'@every 5s'. Can we use minutes or hours or month or week?

Have a poke around https://crontab.guru/, it has a nice visualiser as well as examples that will help clarify this.
