Now months have numbers in japanese but in many countries that officialy use only numbers for naming months they have old traditional names for each month and sometimes for specyfic day (in example full moon days have they own names). These names are often not used officialy anymore but they exist (usualy remembered as a fun fact). Do months had names in Japan in the past?
Fun fact. In Poland, astronomy fans sometimes use names for full moon (they are borrowed from other countries). The full moon in February is named Snow Moon. I remembered it becouse of Word Garden.
