+## 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.
+ {{% /note %}}
