Cron Parser

Cron Expression Parser

Cron is the Unix/Linux task scheduler that uses five-field expressions to define a schedule. Each field specifies the minute, hour, day of month, month, and day of week.

Special characters

• * — any value (every minute/hour/day);
• / — step: */5 means "every 5";
• - — range: 1-5 means "from 1 to 5";
• , — list: 1,3,5 means Monday, Wednesday, Friday.

Frequently Asked Questions

• What should I do if the parser shows "Error in minutes" for the value 60?

  The minutes field must be in the range 0–59. If you want to run a task every hour at the "60th minute", that field is invalid — use 0 (zero minutes) instead. The parser automatically explains the reason for the error so you can correct the expression right away.

• Why does the expression 0 0 * * 0 run only on Sundays and not every day?

  The fifth field (day of week) with value 0 or 7 means Sunday specifically. If you want to run a task every day, replace the last field with an asterisk: 0 0 * * *. The parser visually explains this logic by showing only Sunday dates in the schedule.

• Can the parser display run times in my timezone if the server is set to UTC?

  Yes, the tool has a timezone selector. UTC is set by default, but you can switch to your local time. The next 10 run times will be calculated with your timezone taken into account, which is critical when checking tasks scheduled at, for example, 3 AM Moscow time.
