Cron every Monday at 08:00: the expression, explained, in GitHub Actions

The cron expression for “every Monday at 08:00” is 0 8 * * 1. This page shows what each field does, the next five times it will fire, the mistake most people make with it, and a working GitHub Actions example you can paste.

Mistakes people make with this schedule

Filling both day-of-month and day-of-week. In classic cron they combine with OR, so "0 8 1 * 1" runs on the 1st and on every Monday.
Assuming the server clock is your clock. Cron runs in the machine’s timezone unless the runtime says otherwise; the examples here are UTC.
No lock around a job that might overlap itself, and no alert when it silently stops. That second one is what Supercrontab is for.

Run it in your stack

Linux crontab Laravel WordPress Next.js / Vercel Node.js Python Docker GitHub Actions

# .github/workflows/cron.yml
on:
  schedule:
    - cron: '0 8 * * 1'
jobs:
  run:
    runs-on: ubuntu-latest
    steps:
      - run: curl -fsS https://example.com/cron/run

Scheduled workflows can be delayed by many minutes at busy hours, and are disabled after 60 days of repo inactivity.

Questions

Does 0 8 * * 1 run in my local time?

Only if the scheduler is configured for it. crontab uses the system timezone; Vercel and GitHub Actions always use UTC; Laravel and node-cron take a timezone option. In Supercrontab the timezone is a field on the job.

What if the previous run is still going?

Classic cron starts the next run anyway. Add a lock (flock on Linux, withoutOverlapping() in Laravel) or let Supercrontab skip the tick while the previous request is open.

Is there a shorter way to write this?

No. The five-field form is the shortest portable version.
