Refill Mystery

OK clever people do you know the answer to this one? Judith contacted me this morning with this question:

"I was wondering if you could help me with an A5 refill mystery.

I’m using Time/System A5 inserts in my A5 Filofax, in the 2 pages per day format.

While I was investigating my options for next years refills, I made a strange discovery.

All UK and US suppliers of 2PPD inserts (Franklin Covey, Day Runner, Day Timer) have the notes page on the right-hand side and the timetable/Todo’s on the left-hand side.

While German suppliers (Time/System, Chronoplan, Zeit&Plan, Bind) have the notes page on the left and the timetable/Todo’s on the right.

I was wondering what might be the cause for this? Should be a simple copycat-syndrome, or is there actually a more profound reason behind all this?"

To illustrate, here is the Time System page:

And if you got to the Franklin Store you will see the difference.

I was wondering that in publications important information is always put on odd numbered pages. So the appointments would always be on the right hand side

So what do you think the reason might be?
