We all use this O’clock while telling time but have you actually thought about what it stands for?
It means 7 of clock!
Why do we say so?
Well, it’s simply a remnant of the times when a variety of sources were used to tell the time and clocks weren’t used or weren't as prevalent during that time.
Generally sun was used as a reference point and so to distinguish that one was referencing a clock’s time than the sundial in the 14’th century, people would say “It is 7 of the clock” which, after being used again and again came down to “7 O’clock” around the 17’th century!
So that means we don’t really need to say O’clock since we never refer to the sundial now, Isn’t it?
