Cron Expression

What is a Cron Expression?

A Cron Expression is a string that defines periodic scheduling following a specific format.

The field Cron Expression accepts schedules with the following fields:

<minute> <hour> <day of month> <month> <day of week>

To fill in the fields, you can use numbers and some special characters:

  • * means "all";

  • ? means "any" and can be used for month and day of week;

  • L means "last" and can be used for month and day of week;

  • First three letters of days of week (like MON and TUE);

  • , means a list of values (only the specified values);

  • - means a range of values (all the values included in the range);

Here are some examples of Cron Expressions:
