Monday, January 11, 2027
Official observances, world days, local context, and everyday celebrations for people who need something worth reading, sharing, or talking about today.
World Calendar Day
World Good Neighbor Hello Day
A day for the first greeting, the open door, and the small courtesies that make streets, villages, apartments, and shops feel human.
Regional/Cultural Day
Kagami Biraki
The mochi that was offered to the deity at New Year's (kagami mochi) is broken and eaten on January 11th. The mochi is not cut with a knife (which would be inauspicious) but broken by hand or with a wooden mallet. The broken mochi is cooked in ozoni (mochi soup) or toasted and eaten with sweet bean paste. The act of breaking the mochi symbolizes the breaking of the old year's mirror and the start of the new.
Regional/Cultural Day
Seijin no Hi
The second Monday of January is Coming of Age Day, when everyone who turned 20 in the past year (the age of majority in Japan until 2022, when it was lowered to 18) celebrates their entry into adulthood. The women wear furisode (long-sleeved kimono) that cost thousands of dollars and are worn only once. The men wear hakama or suits. The ceremony at the local city hall is formal, and the after-party at the izakaya is not.
Regional/Cultural Day
Japan Receipt Drawer Day
A day for the proof of purchase nobody can find until the warranty is over.
Regional/Cultural Day
Rain Plan Day
A day for umbrellas, towels by the door, backup shoes, covered stalls, and the local wisdom of wet weather.
Regional/Cultural Day
Animals of Slovakia Day
You spot the brown bears, gray wolves, and lynx that roam the High Tatras mountains and forests of Slovakia. You typically see pet dogs, cats, and rabbits as common household animals throughout Slovak homes. ACADA celebrates the world's pets, and helps assure better care.
