Indeed it is. I was going to answer Carsten' mail, but Mark has beaten me

Precisely so. The ancient Greek calendar was also exactly like that - or
perhaps I should have said 'calendars', as the Greek were fiercely and
each city state, it seems, had its own month names, and its own system for
intercalating the 13th month and of course had to have a different New
year from its neighbor :)
