Ideas:

1. The three initial glyhphs in Tuesday, Wednesday and Thursday seems similar, though Tuesday has 7 internal markings, whereas Wednesday and Thursday have 6 such markings.

I guess this means there is some kind of connection between them, and a closer such between Wednesday and Thursday.

Possibly there is a story hidden here.

2. If there is a story hidden in these three days I guess (influenced by recently having read Sahlins' book 'Islands of History') this story is about the stranger (warrior) arriving over the sea to an island (Tuesday), taking possession of everything there (Wednesday) and becoming its new king (Thursday).
