Cron expression for every month on the 15th

In a crontab

Run crontab -e and add:

0 0 15 * * /path/to/your-script.sh

Remember: system cron won't tell you when this job fails or silently stops running. If the schedule matters, add a heartbeat monitor so you get an alert when a run goes missing.

Monitored, with one extra line

Keep the job exactly where it runs today — just append a ping, and SteadyCron alerts you when a run doesn't arrive on schedule:

0 0 15 * * /path/to/your-script.sh && curl -fsS https://ping.steadycron.com/<token>

Works from any language, shell, container, or CI — anything that can make an HTTP request. How heartbeat monitoring works →

As code, with SteadyCron

Define the schedule in a YAML manifest, review it in a pull request, and let SteadyCron call your endpoint — with retries, timeouts, and an execution log:

jobs:
  - id: my-job
    name: my-job
    kind: http
    method: POST
    url: https://api.example.com/tasks/run
    schedule: "0 0 15 * *"
    timezone: Europe/Berlin
    retries: 3

Then steadycron sync steadycron.yaml — or manage the same job with the Terraform provider.
