睦月 (mu-tsuki) "January" (archaic)
Like many countries, Japan uses a 12-month calendar. The names are very simple. January is literally "Month One", February is "Month Two", etc:
一月 = January
二月 = February
However, before the Meiji Restoration (mid-1800s) it was common to use an older 12-month system. These months’ names referenced the weather and the seasons.
In this older calendar, January is 睦月.
睦 = good relationships
月 = month
or, "The Month of Good Relationships"
