Calender, date-block and islamic knowledge.Is it regional?

Assalaam Alaikoum dear brothers and sisters,
We use date-blocks which have ayats and good reminders, stories about islam and some beneficial knowledge about islam and even about daily life on them.You can see them almost in every house and shop in Turkey.Other than learning the date and the local salat times, one can get lots of good knowledge of Islam , islamic life and history from them.They are very handy.
I just wonder , is it a regional thing.Do you have that kind of date-black in your country?
If you don't have, maybe someone should start it there , too.
I put pictures of it.Have a look at them.

this is the card board of the blocks.There are mostly pictures of mosques, nature, Kaabe, etc.Under the pic , there is usually information of a shop which delivers it to its customers.
