Before that, the holiday was usually just called the "NewYear". Because the traditional Chinese calendar is mostly based on the changes in the moon, the Chinese New Year is also known in English as the "Lunar New Year" or "Chinese Lunar New Year". This name comes from "Luna", an old Latin name for the moon. The Indonesian name for the holiday is Imlek, which comes from the Hokkien word for the old Chinese calendar and is therefore also like saying "Lunar New Year".
