Why use this schedule
The fastest schedule most cron systems allow. It suits near-real-time polling where waiting five minutes is too slow.
- Polling a queue or an inbox for new work
- Heartbeat pings to an uptime monitor
- Flushing a small in-memory buffer to disk
First runs, as an example
Starting from 1 January 2027, evaluated in UTC (the hashed H offset is shown as its range start):

Ready-to-use Jenkins config
Drop this into your project. The expression is the one above.
pipeline {
agent any
triggers { cron('* * * * *') }
stages {
stage('Build') { steps { echo 'Scheduled build' } }
}
}The Jenkins fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Things to watch out for in Jenkins
- H/15 starts every 15 minutes at a hashed offset per job, which avoids every job firing at :00. The preview here assumes an offset of 0.
- Jenkins uses the controller's time zone. Put TZ=Asia/Kolkata on its own first line of the trigger to override it.
The common mistake with this schedule
A job that takes longer than one minute will overlap with the next run. Guard against it with a lock, Quartz @DisallowConcurrentExecution, or concurrencyPolicy: Forbid in Kubernetes.
