Cowlitz County Washington webinar
I'm not sure what webinars your question pertains to. The webinars listed at Learn.extension.org each have a time indicated on the page for the specific event. For example, the webinar event titled "Balancing Competing Commitments" has an event page at https://learn.extension.org/events/2015 and shows that it will be held Tuesday, March 17 at 12:00 pm EDT.
If there is a specific webinar or set of webinars you are asking about, let me know what they are and I'll try to be helpful or point you to someone who is in charge of those webinars.
