Antonym of "recurrent"

Question

What is the antonym of recurrent? This is like I have to few activities which I have to perform each month so these are recurrent but there are few activities which I only perform once. So what should I say this activity is recurrent and that activity is one time? What is the proper word in this situation?

The most direct and obvious answer for an active that occurs just one time is a one-time activity, or a one-shot one. But isn’t that already in your question? — tchrist, Mar 15 '13 at 16:07
Question seems to be wrongly phrased. Why are you assuming that the word you are looking for would be an antonym of "recurrent"? — Mohit, Mar 15 '13 at 16:35

One-time, one-off, and in some situations, one-shot will all fit the bill. Also singleton and nonce.

You could try isolated or one-off.

seldom
infrequent
non-periodic (not a good one but can be usable in certain situations)

I think there can be multiple words that can be used depending on how you like it.
