Introduction
Quick — what's the cron expression for "every weekday at 3:15 AM"? If you just opened a browser tab to look it up, you're not alone. No matter how many times you've written a cron job, the syntax never sticks.
Why Cron Syntax Never Sticks
Cron's five-field format looks simple on paper:
┌───── minute (0-59)
│ ┌───── hour (0-23)
│ │ ┌───── day of month (1-31)
│ │ │ ┌───── month (1-12)
│ │ │ │ ┌───── day of week (0-7)
│ │ │ │ │
* * * * *
But beyond the basics, it gets confusing fast:
- What's the difference between
*/5and5? - Is Sunday
0or7? (Both, actually.) - How do you combine day-of-month and day-of-week without conflicts?
Throw in extended syntax with @yearly, @reboot, or six-field formats, and even experienced sysadmins reach for Google.
The Crontab Google Cycle
You know the pattern: open browser, search "cron expression every 15 minutes," land on crontab.guru, copy the expression, paste it in. Two weeks later, repeat.
It works, but it's slow and breaks your flow. And on a headless server with no browser, you're stuck with the crontab man page.
Just Ask in Plain English
With plztell.me, you skip the browser entirely. Just describe what you want in natural language:
plz crontab for every weekday at 3am
plz cron expression to run every 15 minutes
plz cron job for the 1st and 15th of every month at midnight
You get the exact cron expression, right in your terminal, in seconds. No browser tab, no context-switching, no deciphering Stack Overflow answers.
Explain Cron Expressions You Inherited
Half the time, you're not writing a new cron job — you're staring at one someone else wrote and trying to figure out what it does. The expression 0 */6 * * 1-5 in a crontab you inherited from a colleague who left the company doesn't come with documentation.
Just ask:
plz "explain this cron expression: 0 */6 * * 1-5"
plz "what does this cron mean: 30 4 1-7 * 1"
You get a plain-English breakdown — no mental gymnastics required. And if you want to modify it, just follow up:
plz change that to run on weekends instead
Context is preserved, so the AI knows exactly which expression you're referring to.
