Days are a construct.
We have a sequence
of nights and days,
that have been sorted
into groups of seven.
These were given names,
around the world,
that individualise them within a week,
but they are not unique.
A Wednesday rocks up,
then, seven days later,
it rocks up again –
as do the other days.
They give storms and hurricanes
individual names –
perhaps restricting ‘them’ to seven
would be possible?
At least they would be further apart
than every seventh day.
