Herodotus – On This Day for WordPress

Herodotus is a specialized tool for creating recurring historical events based on Day and Month, making it perfect for “This Day in History”, birthdays, anniversaries, or any annual recurring timeline.

Unlike the default WordPress behavior where posts are tied to a specific publication year, Herodotus introduces its own herodotus_post Custom Post Type. You simply pick a day and a month from the custom date picker in the block editor, and your post will automatically appear on that exact day every single year.

Key Features:

Dedicated Custom Post Type — keeps your regular blog posts completely separate from historical events.

Custom Taxonomy — group historical events into categories like “Science”, “Politics”, “Birthdays”, etc.

Annual Recursion — just set “May 15” and the post appears every May 15, forever.

Three Layouts — standard list layout for pages, compact layout for sidebars and widgets, and a plain text layout with no images at all.

Shortcode & Gutenberg Block — use [herodotus] or the included block to display events anywhere.

Year Support — set the year of the event for display purposes.

Year Badge — the historical year is displayed as a badge on each event card, so visitors immediately see when the event occurred.

BC/AD Era Support — mark events as BC or AD. BC events are sorted chronologically before AD events. The “AD” label is shown in the year badge when selected.

Category Filtering — display posts from a specific category using [herodotus category="history"].
