How to define a video's start and end date?

Is there a simple way to define a video start and end date, by calendar day and time?

I have a video landing page that needs to launch the video at a specific time, looking as its "live".

html page defines video within the page like:

<div align="center" class="embed-responsive embed-responsive-16by9">
<video autoplay loop class="embed-responsive-item">
<source src="Walker360 Webinar - Draft 2.mp4" type="video/mp4">
