IMDb Age & Movie Year Calculator by Kargi

IMDb shows birth dates and release years, but you always have to do the math yourself to figure out someone's actual age or how long ago something came out. This extension just does that math for you, everywhere on the site.

This is a lightweight browser extension for Firefox that adds two small but genuinely useful bits of context to IMDb:

• On an actor/person page, it calculates and displays their current age right next to their birthdate.
• On a movie/series page, and anywhere a title shows up in a list (search results, filmography, cast lists, "more like this", etc.), it shows how many years ago that title was released.
• On actor pages specifically, you can switch a setting so that instead of "years ago," it shows how old the actor was when each of their movies/series came out.
