The cron expression for every weekend is 0 0 * * 6,0. Here is what each field means, when the job runs next, and how to know if it stops running.
| Field | Value | Meaning |
|---|---|---|
| Minute | 0 | At minute 0 |
| Hour | 0 | At hour 0 |
| Day of month | * | Every day of the month |
| Month | * | Every month |

6 is Saturday and 0 is Sunday (7 also means Sunday in most implementations). With * * * * 6,0, the job would run every minute of the weekend.
Cron doesn't tell you when a job is skipped, crashes or hangs. Create a Hyperping healthcheck in cron mode with 0 0 * * 6,0 and the job's timezone, add one curl to the end of the job, and you're alerted when a run is missed. Free for up to 20 jobs.
