[['prom', 'subclass of', 'ball']]
In Canada, the terms "formal" and "Grad" are often used, while in Australia and New Zealand, the terms school formal and <entity_1> are most commonly used for occasions equivalent to the American <entity_0>, and the event is usually held for students in Year 12, although the bestowing of the regal titles does not occur. In Hong Kong, <entity_0> culture is inherited from the western countries and is generally called a <entity_1>, such as Christmas Ball. Conversely, if a high school has separate dances for juniors and seniors, the term "<entity_0>" is reserved for the juniors, and the dance for the seniors is called a "graduation <entity_1>" (often abbreviated as "grad <entity_1>" or simply "<entity_1>".) In Estonia, the equivalent of the <entity_0> is often called Saja päeva <entity_1>. In Finland, the equivalent of the <entity_0> is called vanhojen tanssit (senior <entity_1>). This <entity_0>-like evening dance is traditionally held in the <entity_1> season of January–February, but November-December has gained popularity in recent years as well. Afterward, the <entity_0> continues as a school <entity_1>, traditionally with classic dances.
