Kwan Tai's Birthday(关帝诞Guāndì Dàn) falls on the 24th day of the sixth lunar month.

Worshipped somewhat paradoxically by both police and the secret societies they investigate, it could be said that Kwan Tai has the crime and punishment market very well cornered. But the erstwhile Han dynasty(202 BC - 220 AD) general, who became immortalised as the God of War, is widely regarded as a symbol of loyalty and integrity, and therefore appeals to all military-like groups(many Chinese secret societies originated as revolutionary organisations.)

His birthday is marked by elaborate ceremonies across town, including those at the Man Mo Temple on Hong Kong island, where an ever-burning lamp(长明灯chángmíng dēng) flickers before Kwan Tai's statue.
