# Cron Format The Cron format is a simple yet powerful and flexible way to define the time and frequency of various actions. It consists of five fields, each specifying a different time unit. The following graph explains it in detail: ``` * * * * * | | | | | | | | | | | | | | +---- Day of the Week (range: 1-7, 1 standing for Monday) | | | +------ Month of the Year (range: 1-12) | | +-------- Day of the Month (range: 1-31) | +---------- Hour (range: 0-23) +------------ Minute (range: 0-59) ``` Any of these 5 fields may be an asterisk `*`. This would mean the entire range of possible values, i.e. each minute, each hour, etc. Any field may contain a list of values separated by commas, (e.g. `1,3,7`) or a range of values (two integers separated by a hyphen, e.g. `1-5`). After an asterisk `*` or a range of values, you can use character `/` to specify that values are repeated over and over with a certain interval between them. For example, you can write `0-23/2` in Hour field to specify that some action should be performed every two hours (it will have the same effect as `0,2,4,6,8,10,12,14,16,18,20,22`); value `*/4` in Minute field means that the action should be performed every 4 minutes, `1-30/3` means the same as `1,4,7,10,13,16,19,22,25,28`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://readme.directual.com/scenarios/schedule-triggers/cron-format.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
