Ready-to-use node-cron config
Drop this into your project. The expression is the one above.
import cron from 'node-cron';
cron.schedule('30 8 * * 1-5', () => {
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
- Weekdays are 0-7 with Sunday as 0 or 7, and names such as MON-FRI are accepted.
- Five fields: minute, hour, day-of-month, month, day-of-week. Add a leading seconds field for sub-minute schedules.
- 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
The minute comes first, then the hour. 30 8 means 08:30, while 8 30 would be an invalid hour.
