Relative clauses of time, place and reason
Defining and non-defining relative clauses of time, place and reason are possible in which when, where and why are used in place of relative pronouns. They can also replace words like the time, the place and the reason. Though we can say the time when, the place where and the reason why, we cannot say 'the way how* [> 1.47.1]. Note that when follows only 'time' nouns, such as day, occasion, season; where follows only 'place' nouns, such as house place, town, village; why normally follows the noun reason.

1.38.4 ('That') in place of 'when', 'where', 'why'
That is possible (but optional) in place of when, where and why but only in defining clauses:
/ still remember the summer (that)we had the big drought ((That)
can be replaced by when or during which.)
I don't know any place (that)you can get a better exchange rate
((That) can be replaced by where or at which.)
That wasn't the reason (that)he lied to you ((That) can be
replaced by why or for which.)
For relatives after it [> 4.14].
1.39 Relative clauses abbreviated by 'apposition'
We can place two noun phrases side-by-side, separating the phrases by commas, so that the second adds information to the first. We can

then say that the noun phrases are 'in apposition' [> 3.30]. This is more common in journalism than in speech. A relative clause can sometimes be replaced by a noun phrase in this way:
My neighbour Mr Watkins never misses the opportunity to tell me
the latest news (defining, without commas)
Mr Watkins, a neighbour of mine, never misses the opportunity to
tell me the latest news (non-defining, with commas)
(= Mr Watkins, who is a neighbour of mine, ...)
