There are 365.2422 solar days in the mean tropical year. Several solar calendars have a year containing 365 days. [Bryan Bunch, "The Kingdom of Infinite Number". New York: W. H. Freeman & Company (2000): 169] Related to this, in Ontario, the driver's license learner's permit used to be called "365" [http://emily.icomm.ca/isms.html] [http://www.ontla.on.ca/hansard/committee_debates/35_parl/session3/resdev/r013.htm] because it was valid for only 365 days. Financial and scientific calculations often use a 365-day calendar to simplify daily rates.
