Workflow trigger

on:
  schedule:
    - cron: "0 0 1 * *"

The GitHub Actions fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-6, 0 = Sunday).

If both day fields are set, the workflow runs when either matches.
Scheduled workflows only run on the default branch, and public repos pause them after 60 days without activity.
GitHub Actions schedules are always UTC. Convert your local time to UTC before writing the expression.

The month field is 1-12 (January is 1), and the day-of-month field starts at 1, not 0.
