relative to bonne saison or RBS

The obvious event is the so-called ‘bonne saison’, a French zooarchaeological term for the time at the end of winter when rivers unfreeze, the snow melts, and the landscape begins to green. This of course varies by several weeks from the south to the north of Europe, but corresponds approximately to late spring. We hypothesize that spring, therefore, with its obvious signals of the end of winter and corresponding faunal migrations to breeding grounds, would have provided an obvious, if regionally differing, point of origin for the lunar calendar.
