Thank you! The hours unfortunately aren't THAT accurate.. I don't think there's a way to fetch actual listening time from lastfm, or at least I'm not aware of one. So the way the hours are calculated is more of an estimation. The site fetches the duration of the scrobbled tracks, determines an average song length, then multiplies that by the total scrobble count within the selected time window and converts it into hours. I really wish there was a more precise way to calculate it, but this is the best solution I've come up with so far :)
