24/7/365 has appeared more regularly in the last couple of years or so, and is of course inspired by the use of the term 24/7 to mean ‘all the time’, i.e. 24 hours a day, 7 days a week. With its embellishment of 365, this new variation emphasizes the fact that something happens not only all day, but also on every day of the calendar year, with no breaks for weekends, public or other holidays. However unlike days and weeks, which unequivocally contain 24 hours and 7 days respectively, the number of days in a year varies once every four years. In 2012 there was therefore some evidence for use of a modified version 24/7/366, taking into account the extra day afforded by a leap year.
