Mother's Day

It is Mother's Day in Germany.  I do not know why it is the 4th Sunday in Lent in the UK but the second Sunday in May in Germany.  Or why it's the 22nd December in Indonesia or the second Sunday in February in Norway.

It's all a bit nuts.

Which was not the reason for today's Blip of nuts.  

A nut for a bolt is called "eine Mutter" (and a bolt is "eine Schraube") and I thought I'd make my version of Muttertag.
