The practice of saying “o’clock” is simply a remnant of simpler times when clocks weren’t very prevalent and people told time by a variety of means, depending on where they were and what references were available.
Generally, of course, the Sun was used as a reference point, with solar time being slightly different than clock time. Clocks divide the time evenly, whereas, by solar time, hour lengths vary somewhat based on a variety of factors, like what season it is.
Thus, to distinguish the fact that one was referencing a clock’s time, rather than something like a sundial, as early as the fourteenth century one would say something like, “It is six of the clock,” which later got slurred down to “six o’clock” sometime around the sixteenth or seventeenth centuries. In those centuries, it was also somewhat common to just drop the “o’” altogether and just say something like “six clock.”
Using the form of “o’clock” particularly increased in popularity around the eighteenth century when it became common to do a similar slurring in the names of many things such as “Will-o’-the wisp” from “Will of the wisp” (stemming from a legend of an evil blacksmith named Will Smith, with “wisp” meaning “torch”) and “Jack-o’-lantern” from “Jack of the lantern” (which originally just meant “man of the lantern” with “Jack,” at the time, being the generic “any man” name. Later, either this or the Irish legend of “Stingy Jack” got this name transferred to referring to carved pumpkins with lit candles inside).
While today with clocks being ubiquitous and few people, if anybody, telling direct time by the Sun, it isn’t necessary in most cases to specify we are referencing time from clocks, but the practice of saying “o’clock” has stuck around anyway.
Bonus Fact:
- The word “clock” is thought to have originally derived from the Medieval Latin “clocca,” meaning “bell,” referencing the ringing of the bells on early town clocks, which would let everyone in a community know what time it was.
- Contrary to popular belief, the clock tower in London commonly called “Big Ben” is not named “Big Ben.” Rather, it is named “Elizabeth Tower,” after Queen Elizabeth II; named such during her Diamond Jubilee (the 2012 60th anniversary of her accession to the throne). Before that, it was just called “Clock Tower.” So why is it so often called “Big Ben”? That is due to the great bell inside the tower that chimes the hour out and goes by that name. Over time this has morphed into many calling the clock tower itself that even today, despite the recent, very public, name change.
- The Tower of the Winds in Athens, which lies right under the Acropolis, is thought to be the first clock tower in history, constructed sometime between the 2nd century BC to 50 BC. It contained eight sundials and a water clock, along with a wind vane.
- If you’ve ever wondered what a.m. and p.m. stand for, wonder no more: a.m. stands for “ante meridiem,” which is Latin for “before midday”; p.m. stands for “post meridiem,” which is Latin for “after midday.”
- The International Space Station orbits about 354 kilometers (220 miles) above the Earth and travels at approximately 27,700 km/hr (17,211 mph), so it takes about 92 minutes to circle the Earth once. For this reason, every 45 minutes the astronauts on-board see a sunrise or a sunset, with a total of 15 – 16 of each every 24 hours.

In 1923, a senior radio officer, Frederick Stanley Mockford, in Croydon Airport in London, England, was asked to think of one word that would be easy to understand for all pilots and ground staff in the event of an emergency.
