日本のカレンダー - 常識
Japanese calendar - common sense
Japanischer Kalender - gesunder Menschenverstand
Calendrier japonais - bon sens
I like the old meanings: February 二月 (Nigatsu) Kisaragi (如月) or Kinusaragi (衣更着"Changing Clothes").
In Europe, some old saying (also called farmers rules - Bauernregeln) about February:
+ Lots of fog in February, lots of rain all year.
+ If it does not snow in the Hornung (February), the cold comes at the Easter time.
+ In February snow and ice, makes the summer hot.
