Quarterly on the 1st
0 0 1 1,4,7,10 *Runs at midnight on Jan 1, Apr 1, Jul 1, and Oct 1 — quarterly cadence.
Why this pattern
Financial quarters, OKR resets, board-report assembly. 0 0 1 1,4,7,10 * runs at midnight on January 1, April 1, July 1, October 1 — exactly four times per year.
Variations
- Fiscal-year start (UK style, April):
0 0 1 4 * - Every two months:
0 0 1 */2 * - First Monday of the quarter (Quartz):
0 0 9 ? 1,4,7,10 MON#1
Platform notes
Because this only fires four times a year, missed-run handling matters. On Kubernetes set startingDeadlineSeconds generously so that a brief control-plane outage does not cause the quarterly job to skip until next quarter. On AWS EventBridge, retries are configured per-target, not per-rule — verify the downstream Lambda/SNS retry policy.
