User blog comment:Spirits of nature/Accurate birth year for the main character/@comment-30307603-20161024195451

First of all, it has been confirmed by Ben Boquelet himeself that Richard and Nicole are both 38 years old. Secondly, it has also been confirmed for years that Darwin is 10 years old as well as Anais being 4 years old.

Also, this is a cartoon. There is no confirmed year when the show takes place. One of the writers himself joked "I can't remember if the show takes place in 1950, 1985, 2010, or 2095." In other words, it's pointless to try to assign a date to the show.
