Common use cases

  • Mid-week summary reports or digests.
  • Weekly jobs deliberately spaced away from start/end of week.
  • Wednesday maintenance windows.
  • Recurring mid-week data refreshes.

Gotchas

  • Day-of-week numbering: Unix uses Wednesday = 3 (Sun=0). Quartz uses Wednesday = 4 (Sun=1). Use name form (`WED`) to avoid the off-by-one.
  • AWS EventBridge: `0 0 ? * WED *` — uses `?` for day-of-month.
  • Pin the timezone so "midnight Wednesday" fires when you intend.

0 0 * * 3 is the Wednesday weekly schedule — the mid-week anchor. Use the name form WED and an explicit timezone for a clean, portable once-a-week cron.

Frequently asked questions

What does `0 0 * * 3` mean?
Minute `0`, hour `0` (midnight), day-of-month `*` (any), month `*` (any), day-of-week `3` (Wednesday in Unix where Sun=0). So the job fires at midnight every Wednesday — one invocation per week.
Why is Wednesday `3` in Unix but `4` in Quartz?
Unix cron numbers days 0–6 with Sunday at 0 (so Wednesday is 3). Quartz numbers days 1–7 with Sunday at 1 (so Wednesday is 4). Use the name form `WED` — it's unambiguous across every dialect.
How do I run on Wednesday afternoon instead of midnight?
Change the hour field. `0 14 * * 3` runs at 2 PM every Wednesday, `0 17 * * WED` at 5 PM. Combine with a timezone pin so the time means what you intend.
