--- layout: docs title: Permalinks prev_section: templates next_section: pagination --- Jekyll supports a flexible way to build your site’s URLs. You can specify the permalinks for your site through the [Configuration](../configuration) or in the [YAML Front Matter](../frontmatter) for each post. You’re free to choose one of the built-in styles to create your links or craft your own. The default style is `date`. Permalinks are constructed by creating a template URL where dynamic elements are represented by colon-prefixed keywords. For example, the default `date` permalink is defined as `/:categories/:year/:month/:day/:title.html`. ## Template variables
Variable Description

year

Year from the Post’s filename

month

Month from the Post’s filename

i_month

Month from the Post’s filename without leading zeros.

day

Day from the Post’s filename

i_day

Day from the Post’s filename without leading zeros.

title

Title from the Post’s filename

categories

The specified categories for this Post. Jekyll automatically parses out double slashes in the URLs, so if no categories are present, it will ignore this.
