What is an antonym for "prior" that is shorter than "subsequent?" [closed]

In a software application, two drop-down lists are presented. The first is labeled "relative period" and is populated with "Prior," "Current," and "Subsequent." The second list is labeled "interval" and is populated with month names, quarter names, and other intervals like "year to date."

I am hoping to find a shorter, less formal-sounding alternative to "subsequent." Does one exist?

Solution 1:

Almost every time I've given or seen these sorts of navigation options (e.g. Google Calendar), the options are Previous and Next. It is often unnecessary to even provide Current; just provide a label to indicate what the currently selected period is.

Solution 2:

How about "following"? http://www.thesaurus.com/browse/prior

Theoretically, "later" or "after" are shorter, but they don't seem to convey the right meaning in that context to me.

Solution 3:

You can use the shortened post- for the opposite of prior.

E.g.,

"Prior to his education, he made very little money. However, the post-MBA scholar quickly found a steady job."

Solution 4:

How about future?

Prior - Current - Future

Solution 5:

Well, posterior is somewhat shorter (although subsequent is not a terribly long word, either). To boot, it is level with prior in style.

Rather rich in meaning, though.
