Weekly
0 9 * * 1
Run once a week, Monday at 09:00.
This preview is live: the table below shows the actual next run times for 0 9 * * 1 in your time zone, recomputed in your browser. Change the expression, dialect, or zone to experiment, then copy the result.
What 0 9 * * 1 means
0 9 * * 1 fires Monday at 9am, the start of the working week and the most popular slot for weekly kickoff automation. Monday is day-of-week 1 in every dialect (the numbering only disagrees about Sunday), so this one ports cleanly.
Start-of-week jobs set the tone for the days ahead: the weekly plan, the sprint kickoff summary, the "here's what's due this week" digest. Because people act on the output immediately, punctuality matters.
Field-by-field breakdown
Unix cron has five fields. Here is what each one is doing in this expression:
| Field | Value | Meaning |
|---|---|---|
| Minute | 0 | minute = 0 |
| Hour | 9 | hour = 9 |
| Day of month | * | every day-of-month |
| Month | * | every month |
| Day of week | 1 | day-of-week = 1 |
Every Monday at 9am in every scheduler
The same cadence written for the seven cron dialects you are most likely to meet. Copy the line for the system you target, the field count and day-of-week numbering differ between them.
| Scheduler | Expression | Copy |
|---|---|---|
| Unix / crontab | 0 9 * * 1 | |
| GitHub Actions | 0 9 * * 1 | |
| Kubernetes CronJob | 0 9 * * 1 | |
| Vercel Cron | 0 9 * * 1 | |
| Quartz | 0 0 9 ? * 1 * | |
| Spring | 0 0 9 ? * 1 | |
| AWS EventBridge | 0 9 ? * 1 * |
When you would use 0 9 * * 1
- Weekly planning digests and sprint kickoff summaries.
- Monday-morning KPI snapshots for the week ahead.
- Generating the week's recurring task list.
The gotcha worth knowing
A bank holiday Monday still triggers this job. Cron has no holiday awareness, so guard human-facing Monday sends with a holiday check or they will fire on long weekends.
