Happy New Year Hawaiian: In the Hawaiian language, the word makahiki means year. The Makahiki season (roughly around October to February time) was celebrated in Hawaii for centuries. In ancient Hawaiian culture, the time of Makahiki was a peaceful time to enjoy harvest, feasts, religious ceremonies and relaxation. The Mahahiki season also defined the transitional time between harvest and new planting — e.g. the new (agricultural) year.
The Hawaiian word hau’oli means happy, cheerful, joyful. While hou means new in this context. So, if you try to literally translate “hau’oli makahiki hou” from Hawaiian to English it would be “happy year new”.
