A year ago, we used mathematics to predict the date and number of the last One Piece chapter based on Eiichiro Oda’s predictions. This week the author estimated finishing the series in 5 years, so we decided to update the numbers.
Contrary to what most people may think, Oda is relatively consistent with its predictions. Of the 7 we know, 5 estimated dates are within a year. Obviously we don’t expect to hit the exact values through math alone, but these calculations are always fun to do, so here are the results for anyone interested.
