<p class='note warning'>
Rendering templates with time (`now()`) is dangerous as trigger templates only update based on entity state changes.

### {% linkable_title Time trigger %}

Time can be triggered in many ways. The most common is to specify `at` and trigger at a specific point in time each day. Alternatively, you can also match if the hour, minute or second of the current time has a specific value. You can prefix the value with a `/` to match whenever the value is divisible by that number. You cannot use `at` together with hour, minute or second.
