This template determines which interval a given value lies in.

The intervals are defined by the unnamed parameters. The value to be determined is named parameter n.

format=time can also be passed to the template. If set, the intervals and value will be compared as times (and if n is not provided, it will evaluate as the current timestamp).

Passing 2, 4 and 6 as the unnamed parameters defines the following intervals:

  • -∞<x<2
  • 2≤x<4
  • 4≤x<6
  • 6≤x<∞

Then:

  • {{Interval|n=1|2|4|6}} gives 0-1 because 1 is in the interval between the 0th and 1st values.
  • {{Interval|n=4|2|4|6}} gives 2-3 because 4 is in the interval between the 2nd and 3rd values.
  • {{Interval|n=5|2|4|6}} gives 2-3 because 5 is in the interval between the 2nd and 3rd values.
  • {{Interval|n=6|2|4|6}} gives 3-4 because 6 is in the interval between the 3rd and 4th values.
  • {{interval|14 October|24 October|29 October|7 December|format=time}} produces 4-5
