Given the enum declaration you can create variables of that type, as in

enum days var;  /* var can assume any 3 values listed in the enum tag declaration */

What?
enums are kinda like an easy way to create #defines keywords with values automatically assigned in a sequence which can be specified in a variety of ways. The values must be integer constants like 2 or '2' .

#include <stdio.h>      /*  enum-2.c  */

int main(void)
{                                                        /* assigned values */
  /*enum days{ mon, tue, wed, thu, fri, sat, sun};            0 1 2 3 4 5 6 */
  enum days{ mon = 1, tue, wed, thu, fri, sat, sun  };     /* 1 2 3 4 5 6 7 */

  int i = 3;
 
  printf("\n mon= %d  tue= %d  wed= %d  thu= %d  fri= %d  sat= %d  sun= %d \n",
           mon, tue, wed, thu, fri, sat, sun );

  if (i == wed)
    printf("It's wednesday \n");

  return 0;
}
