How do you tell it's a New Year without a calendar?

Māori are the indigenous people of New Zealand. Matariki is the Māori name for the cluster of stars visible in our night sky at a specific time of the year. This cluster of stars is also known as the Pleiades in Greek mythology, Subaru in Japan or Makali'i in Hawaii.

Under the maramataka, the Māori lunar calendar, the reappearance of Matariki in the mid-winter night sky heralds the start of a New Year.  
According to Legend, when Ranginui, sky father and Papatūānuku, earth mother were separated by their children, Tāwhirimātea, the god of the winds became so distraught he tore out his eyes and threw them into the heavens.

Matariki means the 'eyes of god'. It's a time for us to look up, acknowledge our departed, welcome the new, and take time to celebrate with family and friends.  
Happy Matariki Aotearoa.
