I really think this is a timezone issue. The code source of your page contains :
<script id="distill-front-matter" type="text/json">
{"title":"Interview with Dr. Dawn Wright","description":"Interview with Dr. Dawn Wright at MozFest","authors":[{"author":"Julie Lowndes & Erin Robinson","authorURL":"#","affiliation":" ","affiliationURL":"#","orcidID":""}],"publishedDate":"2021-03-08T00:00:00.000+00:00","citationText":"Robinson, 2021"}
</script>
Which is the data process by the JS from distill library. As you see the date contains the timezone part.
So for me translated in CET it not the same day as for you I think. I'll look more closely into that tomorrow. Please open the issue in distill repo so we fix this.
