Still alive? Have no fear. Even feng shui master James Lee Shing-chak says today is an especially lucky one.
"It is a day with an abundance of sun and rainwater to nourish the earth, which means farmers see it as a good day for yielding harvests, and couples see today as a good day to get married on."
Lee said there was nothing alarming written in the stars. A happy day it is indeed for the 119 couples tying the knot at marriage registries - which is about the norm for a Friday, according to the Immigration Department.
Doomsday claims centred on today are linked to an interpretation of the end of a five-millennia cycle in the ancient Mayan calendar that began in 3,114BC. Sceptics say it merely signifies the end of an era and the start of another.
Today is special for another reason: the winter solstice, the shortest day of the year, when families typically gather for a reunion dinner.
Buzz Concepts, a management company, held a "Doomsday Party" last night at four of its drinking establishments in Lan Kwai Fong to count down to the end of the world. At 1am, partygoers donned gas masks and shuffled to an "underground quarantine zone", otherwise known as Club Volar on nights when earth is not in peril.
Revellers took complimentary "penicillin shots" and received a "Doomsday survival kit" with "zombie repellant", survival pills (vitamins), lollipops, tissues for drying tears, seeds to plant new life and pieces of paper to record standout moments in life.
Tonight, Aqua Restaurant Group's flagship in Tsim Sha Tsui will serve a six-course "End of the World" meal for HK$2,112.12 per person.
Meanwhile, 21-year-old Andy Tsang capped off what could have been his last night on earth enjoying Hongkongers' favourite pastime - karaoke with friends.
And what did he sing? Britney Spears' Till the End of the World.
