Can anyone think of a phrase we would use to describe a situation where something is the opposite of "out of date"; that is, it's "too new"?

For example, a banana that's been sitting around for ages and is inedible could be described as "out of date", but a green banana that's not yet ripe is at the opposite end of the spectrum. Another example might be an engine part that is too old for a particular model of car; it would be "out of date". But what about if the car is old enough that the part's design has been updated since the car's manufacture, and the replacement part would now be "too new" to operate with the car's engine?

Obviously one way to deal with this latter situation is to turn the sentence round and descibe the car as "out of date", but is there a succinct way to keep the "too new" object as the subject of the sentence and describe it as the opposite of "out of date"?

  • Is the car part analogy a real life situation? It seems unreal to me, since spare parts are designed and manufactured to meet the specifications of a particular engine. A spare part would only be "too new" if the compatible engine were not yet on the market.

    @GoodA.M. Substitute a computer part, then. An out-of-date computer with an out-of-date architecture may not support newer hardware, which is thus ‘not yet in date’. Jan 10, 2015 at 20:49

    Postdated as in a check that can't be cashed.

  • Actually, "green" is a good word for the item of produce, banana or not, and the term is understood in other contexts as well, as "green employee". "Immature" is another word.

    The banana situation and the car part situation are sufficiently different that most good terms won't work for both. They aren't analogous either — the banana will be fine when it eventually ripens, but the car part will still be incompatible. Jan 11, 2015 at 10:48

One way is to use Not yet in date.

That can be used with things like coupons which have a validity period which hasn't yet been reached. In date is a direct opposite of out of date (that is, it says that something is valid); but where out of date implies expiry has already happened, using not yet implies something is still to happen.

While this does work for coupons with a start date, it won't work with the example of the car part. But in that case, I wouldn't say the car engine is "out of date" either. The engine's design is simply too old for the part; or the part's design is too new for the engine.

Premature implies a thing that is before its time.

The green banana is premature until it ripens.

The coupon is premature until the start date.

The spare part is premature for an engine that has not been introduced on the market.

Alternately as suggested by ScotM


The new part for an old engine is post-dated.


As for the banana example, the descriptor would be:

"An unripe banana is green"

To describe the car part that's "too new" for the old engine, one of the most common descriptors is modern, as in:

"We just can't fix this engine with modern parts"

Alternatively, the most accurate descriptor is either postcontemporary or ultracontemporary. Contemporary itself is an adjective used to describe things as belonging to the same time. Postcontemporary indicates that an object exists at a later time than what it is compared to. Ultracontemporary Indicates an object exists in the latest, or most modern time possible. So the best way to say it (if not the most colloquial) would be:

"The engine cannot be fixed with postcontemporary spare parts, especially not the ultracontemporary ones."

To keep this going, other antonyms of out-dated might include (depending on context):

  • Post-modern
  • Futuristic
  • Not backwards-compatible
  • Fresh
  • Trendy
  • ... any more and I become a thesaurus
  • +1 for contemporary. That's the first word that comes to mind when I think of the opposite of “out of date.”

It depends a bit on what you're describing exactly – things can be "up and coming", "avant garde" or "cutting edge" (or "bleeding edge", in particular in IT, if you're not sure it will last or is useful). If you disapprove of the new thing, it can be "newfangled".

In the case of the car part, you could say that it is not backwards-compatible.

From that term, it is understood that the part has been updated (otherwise we'd simply say it was not compatible or was incompatible) and that the updated part does not work acceptably with older versions of the mating equipment.


The opposite of "out-of-date" is futuristic.

But in the sense that you mean, "too new", that would be covered by incompatible or no longer compatible.


One way to say it - "soon to become trendy"

You could also say

  • "soon to become fashionable"
  • "soon to be released"
  • "soon to hit the winning basket"
  • "soon to become popular"

We can say something is "not ready for prime time". It can be an "alpha" version or a "prototype". It can be "untried" or "untested". It can even be "too new" or "fresh from the drawing board". To better answer your question we would need to know the domain.

The popular phrase for things that are generally thought of in that light is, "Ahead of its time"


How about current?

Version 5.1 of the software is outdated. You should update to version 6, which is current.

There's also in vogue but it generally only applies to fashion styles.

Bell-bottoms are no longer in vogue.


The logical opposite of "out of date" is "up to date", however, the possible phrases for what you are looking for (phrase that do not include "current") is "pre-dated", "ahead of one's/its time".

Other similar expressions include "state of the art".

out dated
out of date; obsolete. synonyms: old-fashioned, out of date, outmoded, out of fashion, unfashionable, dated, passé, old, behind the times, behindhand, obsolete, antiquated; More

pre date
past tense: pre-dated; past participle: pre-dated exist or occur at a date earlier than (something). "this letter predates her illness"

ahead of one's (or its) time
innovative and radical by the standards of the time; more characteristic of a later age. synonyms: revolutionary, avant-garde, futuristic, innovatory, innovative, trailblazing, pioneering, groundbreaking, advanced, cutting edge "Leonardo was ahead of his time in almost all endeavors"


Out-of-date implies that something is no longer popular or applicable. Ergo, then when it was useful the words in-date, popular or fad are all antonyms for out-of-date.

Given modern sensibilities with technology you could also use the development terms of alpha or beta as these have definite connotations that the thing that is 'in alpha' or 'in beta' is not yet fully developed. When working with technology these terms can apply to just about anything, and you could easily spread their use to other creative developments such as "I'm writing a new song, but I don't want to share it just yet as the lyrics are still in alpha."

Another term I don't think I saw in the previous answers is 'premature' depending on what context you have.


You could be snarky and describe it as "pre-obsolescent."
