Type a cron schedule and read, in plain English, exactly when it runs — with every field broken out.
Five fields: minute hour day-of-month month day-of-week. Supports *, ranges (1-5), steps (*/15) and lists (1,3,5).
Cron's five-field syntax is compact but easy to misread, and a small mistake can mean a job runs every minute instead of once a day. Type an expression and this tool translates it into a clear sentence, then shows each field — minute, hour, day-of-month, month and day-of-week — separately so you can confirm your intent. It understands the common operators: * for "every," ranges like 1-5, steps like */15, and lists like 1,3,5.
From left to right the fields are minute (0–59), hour (0–23), day of month (1–31), month (1–12) and day of week (0–6, where 0 is Sunday). A classic gotcha is setting both day-of-month and day-of-week, since in standard cron the job runs when either matches. When you're unsure, build the schedule one field at a time and read the description after each change until it says exactly what you mean.
