What it means
0 0 1 1 * runs once a year, at 00:00 on 1 January, which is what @yearly and @annually stand for in crontab(5) and Kubernetes. Any fixed date works the same way: 0 9 25 12 * is 9:00 on 25 December.
When this is the right schedule
Use it when the work is genuinely annual: archiving last year's data, renewing a yearly licence check, resetting yearly counters.
When to pick something else
Look elsewhere when you want 29 February: 0 0 29 2 * only runs in leap years, so it can go four years between runs. Use 28 February or 1 March.
Things to watch
Quartz and AWS have a year field
Quartz's optional seventh field and AWS's sixth limit the years: 0 0 0 1 1 ? 2027 runs once, on 1 January 2027. Unix cron and Spring have no year field.
Spring's Christmas example
Spring's docs use 0 0 0 25 DEC ? for "every Christmas Day at midnight": month names work and ? is accepted in day of week.
New Year in whose timezone?
In UTC, 1 January 00:00 is still 31 December in the Americas. If the date has to match your users, set the schedule's timezone.
