Mistakes people make with this schedule

Filling both day-of-month and day-of-week. In classic cron they combine with OR, so "0 20 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

// WP-Cron only fires on page loads. Disable it and call wp-cron.php
// from a real scheduler instead:
// define('DISABLE_WP_CRON', true);

On low-traffic sites WP-Cron drifts. An external caller makes it exact.

Questions

Does 0 20 * * 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.
