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

Ready-to-use node-cron config
Drop this into your project. The expression is the one above.
import cron from 'node-cron';
cron.schedule('* * * * *', () => {
console.log('running a task');
}, { timezone: 'UTC' });The node-cron fields, in order: second (0-59), 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 node-cron
- Steps restart at the top of each unit, as in standard cron, so */7 in minutes runs at 0, 7 ... 56 and then at 0 again.
- node-cron uses the server time zone unless you pass { timezone: "Asia/Kolkata" }. Its documentation advises timezone: "UTC" for jobs that must not skip or repeat when clocks change.
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.
