« first day (1 day earlier)    last day (4278 days later) »

At meta.SO they have separate tags notifications and comment-replies.
For some of things we have under the tag would be more suitable, I guess. But I am not sure if it's worth creating a new tag.
But I guess that more questions concerning both of them will come in the future and separating them might be useful.
(I did not consider this important enough to bring up at meta, but I'll be glad to hera your opinion.)
