Display trivia daily via shortcode. Add them manually, or upload a csv file with hundreds at a time. You can also have multiple categories of trivia each with their own shortcode. The database repeats every year or you can add more trivia. If more than one entry exists for a day, it will rotate each entry that day.
csv example:
0624, Trivia1 title, Trivia2 title,
On June 24th each year, that trivia will be displayed. If more than one entry exists (trivia2, etc.) it wil rotate them.
This version tested for WP6 and PHP8
