Cron Expression
Cron Schedule Expression
A string format representing a schedule using five fields: minute, hour, day, month, and day of week.
Detalhe técnico
A cron expression uses five space-separated fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7, where both 0 and 7 mean Sunday). Special characters include * (any), , (list), - (range), / (step), and some implementations add a sixth field for seconds. Common patterns: '0 */2 * * ' (every 2 hours), '0 9 * * 1-5' (weekdays at 9am), '/15 * * * *' (every 15 minutes).
Exemplo
``` # Cron expression format: # ┌───── minute (0-59) # │ ┌───── hour (0-23) # │ │ ┌───── day of month (1-31) # │ │ │ ┌───── month (1-12) # │ │ │ │ ┌───── day of week (0-7) # │ │ │ │ │ 0 9 * * 1-5 # Weekdays at 9:00 AM */15 * * * * # Every 15 minutes 0 0 1 * * # First day of each month ```
