Anyway the Roman version would have been in Latin:
Dies triginta habent September, Aprilis, Junius et November...
...but I'm not sure how it went before Augustus stole a day from February.
It was a stern school (Scotland during WW II). Actually we didn’t have Kindergarten...straight into Primary 1. Did learn a bit of Latin, come to think of it, but all of it in hymns and responses to the Mass...not much of it flawless. I know I got a good whack by a pitiless Nun while singing the Tantum Ergo. I thought the last line was “no peace on earth in patria” instead of “nobis donet in patria”. Now in my advanced years, I still insert “no peace on earth” quietly for the hell of it, and get away with it.
