Where in the US aviation regulatory literature is the time limit of a

calendar month or a year to the date it was last performed.

Where is the reference that clearly lists the time limit?

It is in the Operating Limitations that are issued for each Experimental
certification. Some times those OLs don't get passed on to subsequent owners.
