According to an article in the MyHeritage Blog:

"Last year, MyHeritage teamed up with Legacy Family Tree Webinars to make history: we hosted the first-ever 24-hour genealogy webinar marathon. The event, conceived toward the beginning of the pandemic-related shutdowns worldwide, was meant to provide a fully online learning experience bringing together genealogists from all across the globe to hear the latest news, ideas, and advice from the world’s top experts. It was such a success that we’re doing it again: on April 8–9, 2021, we’ll be hosting the second annual 24-hour genealogy webinar marathon!

"Just like last year, the entire event is free and open to all. You can pop in for just one or a few of the lectures that most interest you, or challenge yourself to stay tuned in to the entire event. Live Q&As will take place during the lectures and there will be door prizes available as well."

Also:

"Wrong time zone? Too busy? Can’t drag yourself out of bed at 2 A.M.? (Not that you need to — you can join with a mobile device right from your pillow!) No worries. All the lectures will be available for free viewing on the Legacy Family Tree Webinars website for a week after the event."
