Saved Cron Schedules
Bookmark cron expressions with a description.
Overview
The Saved Cron Schedules tool is a personal bookmark list for cron expressions. Save an expression like */15 * * * * alongside a human-readable description ("poll inbox every 15 minutes"), and the list is kept in browser storage so you can come back to it whenever you need to copy the same schedule into a new system.
Useful for sysadmins who reuse the same handful of schedules across servers, DevOps engineers building Helm charts and CI pipelines, hobbyists running home-automation jobs, and developers who keep forgetting whether */15 * * * * or 0,15,30,45 * * * * is the cleaner way to express the same cadence.
How it works
Each saved entry stores the raw five-field cron expression and a free-text label, persisted to browser local storage as a small JSON document. Nothing is sent to the server — your library is private to the device and browser profile, and you can export the JSON at any time to share with a teammate or move to another machine.
The expressions follow standard POSIX/Vixie cron syntax: five space-separated fields for minute, hour, day-of-month, month, and day-of-week, with the usual operators *, ,, -, and /. To preview when a saved expression will next fire, copy it into the cron next-fire times tool.
Examples
"Every quarter hour"
*/15 * * * *
"Weekday mornings at 9 UTC"
0 9 * * 1-5
"Monthly invoice generation"
0 0 1 * *
"Every 30 minutes during business hours"
*/30 9-17 * * 1-5
FAQ
Where is my list stored?
In your browser's local storage, scoped to this domain. It is private to your device and browser profile. Clearing site data deletes the saved list.
Can I share my saved schedules with a teammate?
Export the list to JSON, send it over, and they can import it on their side. Direct sync is not provided since the data stays client-side.
Why use this instead of a comment in crontab?
A central list lets you reuse the same expression across many systems — Kubernetes CronJobs, GitHub Actions, AWS EventBridge, traditional crontab — without retyping. Comments live next to one specific job.
What expression syntax is supported?
Classic five-field POSIX cron with operators *, ,, -, and /. The @hourly, @daily, @weekly, @monthly, @yearly shortcuts are also accepted. Extended Quartz seconds-and-year syntax is not.
How do I preview when an expression will fire?
Copy it into the cron next-fire times tool to see the next ten fire moments in UTC.
