Vitus Wagner's Journal: No years in dates?

Reading my past comments here I notice strange thing - comments are marked by their month and date but not year.

First I've thought that comments older than six month are just deleted.

But reading some of them I've found ut
that I've could write them not later than three years ago.

And all sorted during just month and day

And where there are comments writen in August, September etc.

I do not write to /. too often but surely I've written something in the second half of one of these years
