Dicas e boas práticas
- 💡Use */5 syntax for evenly-spaced intervals like 'every 5 minutes'.
- 💡Day-of-week uses 0=Sunday through 6=Saturday in standard cron.
- 💡If both day-of-month and day-of-week are set, cron matches on either (OR logic), not both.
- 💡Always verify your expression using the next-run-times preview before deploying to production.
