On the course settings page, the start date is 13/08/2020,
when viewing the course content the date is 12/08/2020
What is the theme? Did you try with the standard theme Boost?
I'm using Edumy theme, in the Boost theme the course start date is not displayed on the course page
That is what I thought. The Edumy theme is not from https://moodle.org/plugins/. You need to contact the developers of Edumy. It looks like 00:00 hour somehow belongs to the previous day.
ok thanks very much
