What gets leapt in a leap year

<h1>What gets leapt in a leap year?</h1>

<p>2016 is a leap year in the Gregorian calendar, making it an appropriate time to consider the origin of this rather puzzling term. After all, leap implies that something is being skipped over, but a leap year has an extra day, making it longer than an ordinary year, not shorter. Where is the metaphorical leap in a leap year?</p>

<p><em>Leap year</em> is attested from the 13th century, but probably goes back even earlier, to judge from the Old Norse equivalent <em>hlaup-ar.</em> It is thought that the “leap” refers to the impact of the extra, or intercalary, day upon which day of the week specific dates fall on in the year that follows. In a standard 365-day year, a calendar date which fell on Wednesday in the previous year falls on Thursday. The extra day in a leap year causes calendar dates to move ahead by two weekdays rather than just one. Thus, 2015’s Christmas fell on Friday, but the Christmas of 2016 will take place on Sunday, not Saturday. It is that ‘leaping over’ a day of the week that gives the <em>leap year</em>, and hence also the <em>leap day</em>, 29 February, its name.</p>

<p>Another “leap” term has also been in the news this year: the <em>leap second</em>, which is added periodically to the atomic reckoning of time to keep it in line with solar time (one was added on 30 June 2015). The term <em>leap second</em> is modeled on <em>leap day</em>, but while that phrase has been with us for over 400 years, <em>leap second</em> will be lucky to reach the age of 50. Introduced in 1972, the intercalary second has repeatedly faced calls to be abolished. The World Radiocommunication Conference decided, in 2015, to give the leap second a reprieve – and the topic will be considered again in 2023.</p>
