## Example: Time Passed Since Last Modification

This very simple one-liner uses `now.Unix` to calculate the amount of time that has passed between the `.LastMod` for the current page and the last build of the current page.

{{< code file="time-passed.html" >}}
{{ div (sub now.Unix .Lastmod.Unix) 86400 }}
{{< /code >}}

Since both values are integers, they can be subtracted and then divided by the number of seconds in a day (i.e., `60 * 60 * 24 == 86400`).

{{% note %}}
Hugo's output is *static*. For the example above to be realistic, the site needs to be built every day.
