Cron Expression Builder — Visual Scheduler with Live Preview
Build valid cron expressions by clicking the five fields, read the plain-English description and next 5 run times, then copy to crontab, GitHub Actions or K8s. This free online tool runs entirely in your browser — no data is ever uploaded to a server. How to Use 1. Pick values — click each of the five fields: minute, hour, day-of-month, month, day-of-week. 2. Use presets — every 5 min, hourly, daily midnight, monthly, weekly — one click. 3. Read the outcome — the expression, a plain-English description and the next 5 runs update live. 4. Copy — paste the crontab string straight into your scheduler. Example Set minute 0 and hour 0 for every day to produce 0 0 * — the tool explains it as midnight daily and lists the next five dates.
