In the man of find the -ctime is said to be :

-ctime n 
          File status was last changed n*24 hours ago.  See the comments
          for -atime to understand how rounding affects the interpretation
          of file status change times.

-atime n
          File  was  last  accessed n*24 hours ago.  When find figures out
          how many 24-hour periods ago the file  was  last  accessed,  any
          fractional part is ignored, so to match -atime +1, a file has to
          have been accessed at least two days ago.

I know from here that the ext4 file system stores the creation date , and you can get it using stats , is the status change times they are talking about in the manual the same as the one given by stats ? or precisely , is the ctime the date of creation of a file ?

No, it is the date of the last status change to the file, i.e. writes to file data or metadata.

  • @Kingofkech If the files haven't been modified at all since creation, then it will. If they have had permissions, ownership, name, or size changes (among other things), it won't. Commented Oct 18, 2017 at 15:29
