Cron: Yearly (Jan 1) (0 0 1 1 *)

The cron expression 0 0 1 1 * translates to “At 00:00, on the 1st, in January”. It is one of the most commonly used schedules (yearly (jan 1)).

Two fields are pinned here: day-of-month `1` and month `1` (January), with minute 0 and hour 0. Together they fire the job exactly once a year, at 00:00 on January 1st. This is as infrequent as common cron schedules get - suited to annual tasks like yearly archival, resetting a fiscal-year counter, rotating a long-lived credential, or a "happy new year" send. Because a whole year passes between runs, it is worth pairing this schedule with monitoring or a dead-man's-switch: a job that only fires annually is the easiest one to silently break without anyone noticing until next January.
