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.
