Is there a good synonym for "recency"?
Solution 1:
As far as recency is concerned, recentness appears to be the only synonym available.
However, from what I understand from your question, temporal proximity is what fits your need best.
Solution 2:
There are some synonyms, but the choice of which one to use depends on context.
- Novelty
- Freshness
- Youth
If you want to describe the state of having just happened, recency is your best bet, barring other forms of the same word (recentness and, even more rarely, recentity).
Solution 3:
Here are a few not mentioned yet:
- newness, modernness
- presence (which implies spatial proximity, too)
- contemporaneity
Solution 4:
There are a whole lot of synonyms for recent, so it is not hard to make a noun out of one of them. The following may fit:
- currentness
- contemporariness
