Cron in GitHub Actions

In GitHub Actions, you can schedule workflows using cron syntax inside the on.schedule field.
All cron schedules run in UTC time.

Examples

on:
  schedule:
    # Runs at 5:30 AM and 5:30 PM UTC every day
    - cron: "30 5,17 * * *"

    # Runs every 15 minutes
    - cron: "*/15 * * * *"

    # Runs every Monday at 9:00 AM UTC
    - cron: "0 9 * * 1"

Cron format

┌───────── minute (0–59)
│ ┌─────── hour (0–23)
│ │ ┌───── day of month (1–31)
│ │ │ ┌─── month (1–12)
│ │ │ │ ┌─ day of week (0–6, Sun = 0)
│ │ │ │ │
* * * * *
