-As mentioned in the Sun trigger section, sunrise is a different day than any time prior to midnight.  If you want to trigger an action with a large enough amount of time before sunrise that it precedes midnight, this must be accounted for properly.  One way is to convert the sunrise time to a timestamp (seconds since 1 Jan 1970). Then do the same for the offset desired (in seconds). This is done with the _as_timestamp_ method explained in the [Templating - Home Assistant template extensions](/docs/configuration/templating/#home-assistant-template-extensions) section.
