Build cron expressions with a visual form. Pairs with the Cron Explainer to verify schedules.
Presets
Try it with this example

What is this tool?
Cron expressions schedule recurring tasks but their syntax is cryptic. The Cron Generator builds them visually. Pick minute, hour, day of month, month, and day of week. Use presets like "every hour," "daily at midnight," or "weekdays at 9am." The tool produces the cron string and you copy it. No more memorizing field order or asterisk placement. Pair it with the Cron Explainer to verify: paste the expression and see it in plain English. All generation runs in your browser.
The five fields are: minute (0–59), hour (0–23), day of month (1–31), month (1–12), day of week (0–7, 0 and 7 = Sunday). The generator maps your choices to valid values. "Every hour" becomes 0 * * * *. "Weekdays at 9am" becomes 0 9 * * 1-5. Some systems support a sixth field for seconds; check your environment. The tool focuses on the standard five-field format used by cron, systemd timers, and many schedulers.
Use it when configuring backup jobs, report generation, or cleanup scripts. When setting up CI/CD schedules. When you want to avoid typo-induced "why didn't this run?" debugging. The visual form reduces errors. Copy the expression into crontab, a hosting panel, or a cloud scheduler. Verify with the Cron Explainer if unsure.
All generation is client-side. No server, no storage. Pick your schedule, copy the expression. Cron implementations vary slightly (e.g. Sunday = 0 vs 7); the generator produces standard output. For nonstandard systems, you may need to adjust. Bookmark it for cron creation.
Essential for scheduled task setup.
