Nitzan Ohana I don't have any connection with the dev team at Hashnode, so cannot provide that information. You can calculate average read time using statistics about average reading speeds. Refer to this post https://dev.to/michaelburrows/calculate-the-estimated-reading-time-of-an-article-using-javascript-2k9l

The estimated read time still isn't available in the schema. You can try https://www.npmjs.com/package/reading-time and handle it on your side.
