Adds a Gutenberg block to display the estimated reading time of the current post. Reading speed is customizable from the Settings → Reading screen.

The block as it appears in the editor.
The Reading Time Block plugin calculates and displays an estimated reading time based on the post content.
It uses a configurable reading speed (default: 200 words per minute) and outputs a clean, server-rendered block to the frontend.
This is ideal for blogs, documentation, or any content where you want to set expectations about how long it will take a visitor to read the page.
