Why this tool stays in the browser

Compose a cron string locally for GitHub Actions, k8s CronJobs, and classic crontab without a hosted cron translator. Human-readable next-run hints stay in the tab. Timestamp Converter is for a single instant; this tool is for recurrence. Timezone Planner helps when the schedule is “everyone’s 9am”.

FAQ

Does this register a job on a server?
No. It only builds the expression text.
Which cron dialect?
Standard five-field cron as used by crontab and many CI systems. Confirm your runner’s extra fields (seconds, year) separately.
How do I convert one timestamp?
Use Timestamp Converter, not this generator.
