What it means
0 12 * * * runs every day at 12:00 noon. Cron hours are 0-23, so noon is 12 and midnight is 0; there's no AM or PM. Quartz's tutorial opens with this schedule as 0 0 12 * * ? ("Fire at 12pm (noon) every day"), and AWS uses it in its own example: cron(0 12 * * ? *).
When this is the right schedule
Use it when you want one run a day during working hours, so a person is around if it fails: a daily report, a lunchtime reminder, a mid-day data refresh.
When to pick something else
Look elsewhere when the job is heavy and competes with daytime traffic; overnight is better for that. Also check whose noon: 12:00 UTC is 8 AM in New York in summer.
Things to watch
No AM or PM in cron
0 12 * * * is noon and 0 0 * * * is midnight. A common slip is writing 12 for midnight. For 12:30 PM it's 30 12 * * *; for 6 PM, 0 18 * * *.
Reading the Quartz form
0 0 12 * * ? is second 0, minute 0, hour 12, any day of month, any month, and ? for day of week ("no specific value"). Quartz requires the ? in one of the two day fields; Spring accepts it but doesn't require it.
Weekdays only
0 12 * * 1-5 in Unix cron; 0 0 12 ? * MON-FRI in Quartz and Spring. Note the ? moves to the day-of-month field once day of week is set.
Frequently asked questions
What does 0 0 12 * * ? mean?
Every day at 12:00:00 noon. It's Quartz (or Spring) syntax: seconds, minutes, hours, day of month, month, day of week.
What does 0 0 12 ? * MON-FRI mean?
At noon, Monday to Friday. The ? in day of month means the day of week field decides.
