Acerca de esta herramienta
Fill five cron fields without memorising the syntax. Presets cover hourly, daily midnight, weekdays at 9am and the first of the month.
The expression is standard 5-field cron (minute hour day-of-month month day-of-week). It does not schedule jobs on GraphicByte servers.
Cómo usarla
- Pick a preset or edit the five fields.
- Read the summary to confirm the schedule.
- Copy the expression into crontab, GitHub Actions or your host’s scheduler.
