The full text of what is said and shown.

September means seven. It sits ninth

The year once began in March

According to tradition, the oldest Roman calendar ran ten months, March to December

January and February were added at the front

September once held the seventh place

The names that followed fell two places back

They never caught up

Two months did change. Quintilis became Julius, Sextilis became Augustus

Other rulers tried to claim a month

None of them stuck

Say September, October, November, December out loud and you are counting in a year that no longer exists
