preposition + which

Detailed explanation “when” refers to time. It acts as a time adverbial in attributive clause. Its antecedents are usually time, day, morning, night, week, year, moment, period, age，and so on. Also, it can be replaced by “preposition+which”.

Antecedent 先行词 Relative Adverb 关系副词 It is now a children’s festival , when they can dress up and go to their neighbors' homes to ask for sweets. at/on Halloween at/on which

Relative Adverb 关系副词 Antecedent 先行词 China and Japan have Mid-autumn festivals, when people admire the moon and in China , enjoy moon cakes. at Mid-autumn festival at which

Attention！ “when/preposition + which” is not always used with the antecedents referring to time. If the antecedent referring to time acts as a subject or an object, “which/that” should be used.
