Each month this year we’re bringing you a post under the general title “Things that Count in [Number]” where [Number] will be the month. And naturally each month’s post will contain the [Number] of items (so just one for January, up to 12 for December).
For our purposes the definition of counting includes things which either come in groups of [Number] (eg. four suits in a pack of playing cards) or things which count in [Number] (eg. decimal coinage counting in tens).
