This preview is live: the table below shows the actual next run times for 0 0 * * 6 in your time zone, recomputed in your browser. Change the expression, dialect, or zone to experiment, then copy the result.
0 0 * * 6 means0 0 * * 6 fires at the start of Saturday — day-of-week 6 in Unix. The weekend is the most popular window for disruptive maintenance, because production traffic on many business systems is at its lowest, so jobs that need an exclusive lock or a long quiet window run here.
Saturday-midnight is the front edge of that window: schema migrations, full-table rewrites, large data migrations, and anything you would never dare run during the week.
Unix cron has five fields. Here is what each one is doing in this expression:
| Field | Value | Meaning |
|---|---|---|
| Minute | 0 | minute = 0 |
| Hour | 0 | hour = 0 |
| Day of month | * | every day-of-month |
| Month | * | every month |
| Day of week | 6 | day-of-week = 6 |
The same cadence written for the seven cron dialects you are most likely to meet. Copy the line for the system you target — the field count and day-of-week numbering differ between them.
| Scheduler | Expression | Copy |
|---|---|---|
| Unix / crontab | 0 0 * * 6 | |
| GitHub Actions | 0 0 * * 6 | |
| Kubernetes CronJob | 0 0 * * 6 | |
| Vercel Cron | 0 0 * * 6 | |
| Quartz | 0 0 0 ? * 6 * | |
| Spring | 0 0 0 ? * 6 | |
| AWS EventBridge | 0 0 ? * 6 * |
0 0 * * 6Saturday is 6 and Sunday is 0 in Unix — but * * * * 6,0 (or 6,7) is the idiomatic "weekend" set. Writing * * * * 0-6 covers the whole week, not just the weekend.
0 0 * * 6 means: Run once a week, Saturday at 00:00. 0 0 * * 6 fires at the start of Saturday — day-of-week 6 in Unix. The weekend is the most popular window for disruptive maintenance, because production traffic on many business systems is at its lowest, so jobs that need an exclusive lock or a long quiet window run here.
Use 0 0 * * 6 in the schedule's cron field. Saturday is 6 and Sunday is 0 in Unix — but * * * * 6,0 (or 6,7) is the idiomatic "weekend" set. Writing * * * * 0-6 covers the whole week, not just the weekend.
EventBridge uses six fields with a required year and a ? placeholder in one day field: 0 0 ? * 6 *. Wrap it as cron(0 0 ? * 6 *) in the console or CloudFormation.
Quartz is seconds-first with a trailing year, so the equivalent is 0 0 0 ? * 6 *. Remember Quartz numbers Sunday as 1, the opposite of Unix.
