Variations
Common use cases
- Weekly heavy maintenance during the quiet weekend.
- Long-running batch jobs that shouldn't disrupt weekdays.
- Weekend backups or reindexing.
- Saturday-only recurring tasks.
Gotchas
- Day-of-week numbering: Unix uses Saturday = 6 (Sun=0). Quartz uses Saturday = 7 (Sun=1). Use name form (`SAT`) to avoid the off-by-one.
- AWS EventBridge: `0 0 ? * SAT *` — uses `?` for day-of-month.
- Pair with `0 0 * * 0` (Sunday) using `0 0 * * 6,0` to cover the whole weekend.
0 0 * * 6 is the Saturday weekly schedule — the classic slot for heavy maintenance that benefits from quiet weekend infrastructure. Use name form SAT and pin the timezone.
Frequently asked questions
What does `0 0 * * 6` mean?
Minute `0`, hour `0` (midnight), day-of-month `*` (any), month `*` (any), day-of-week `6` (Saturday in Unix where Sun=0). So the job fires at midnight every Saturday — one invocation per week.
Why is Saturday `6` in Unix but `7` in Quartz?
Unix cron numbers days 0–6 with Sunday at 0 (so Saturday is 6). Quartz numbers days 1–7 with Sunday at 1 (so Saturday is 7). Use the name form `SAT` — unambiguous across every dialect.
How do I run on both Saturday and Sunday?
Use `0 0 * * 6,0` (Saturday and Sunday in Unix) or `0 0 * * SAT,SUN`. See the dedicated weekends pattern for the full reference.
