I mean, the actual source for this statistic is usually “The Overworked American: The Unexpected Decline of Leisure” by Juliet Schor who in turn got the number from an unpublished paper written by Gregory Clark in 1986. Clark did eventually publish a paper in 2018 where he increased his estimate to 250-300 days (which may still be less than some modern workers work).

And also: this was before the 8h day. People worked until they were done which was sometimes much more but on average less
