From The Free On-line Dictionary of Computing (30 December 2018) :

      A set of real numbers bounded by two real
     numbers - the endpoints or bounds.  The set may or may not
     include either endpoint, leading to four possibilities:
      closed                   [a, b]  a <= x <= b
      open                     (a, b)  a < x < b
      left-open, right-closed  (a, b]  a < x <=b
      left-closed, right-open  [a, b)  a <= x < b
     See closed interval, open interval.

From Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  INTERVAL. A space of time between two periods. When a person is unable to 
  perform an act at any two given periods, but in the interval he has 
  performed such act, as when a man is found to be insane in the months of 
  January and March, and he enters into a contract or makes a will in the 
  interval, in February, he will be presumed to have been insane at that time; 
  and the onus will lie to show his sanity, on the person who affirms such 
  act. See Lucid interval.
