An intentional exercise in confusion? I hope not, but that may be the result.

Can you spot the difference between these two bus schedules? The version on the left is a year old and the version on the right is almost two years old.

The two versions look almost identical, and they are both currently available on the buses.

Why would the bus company do this? If a new and revised version is produced then why not prominently label it as such as remove the old schedules from the buses. If, on the other hand, there are no differences between the two why are the dates different?

Creating confusion is never a good policy.
