This isn't anime related but it's happening in Japan.
Rocketnews24 writer Steven, recently reported about a very interesting calendar that features sexy ladies but it's not the sexy ladies in fetish poses that make this calendar so desirable (but that does help).
It's the fact that these attractive girls have the month and date displayed on various parts of their body.
From thighs, to arms, to breast to knees and everywhere in between, the 365 days are displayed somewhere on the female body.
The female body calendar is known as Nyotai-Goyomi in Japan.
You can read the entire article and see the various pics of the dates on the ladies body here.
