Cron Expression Generator
Cron expressions define recurring schedules but are easy to get wrong. Use presets or simple fields to assemble a valid five-field cron string, and read a plain-English explanation of exactly when it will run — so your scheduled jobs fire when you expect.
Use * for “every”, numbers for specific values, 1-5 for ranges, 1,3,5 for lists, and */15 for steps.

Frequently asked questions
What do the five cron fields mean?
In order: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–6, Sunday=0). An asterisk means every value.
Does this support seconds or special syntax?
It generates the standard five-field crontab format. Some systems add a seconds field or macros like @daily; check your scheduler's docs if you need those.
