At least german office culture knows of a quite popular 3-month format in a physical printed wall calendar, usually highlighting the current month and showing the preciding and following months with less contrast. They are distributed for free or very low cost as promotional product for any type of business. From my understanding Bürokalender as in office calendar is often used synonymously for this format in Germany, which can be seen as an indicator to it's ubiquity. The format seems not to be that popular, elsewhere but at least in the UK it's marketed as shipping calendar, which was the use case for what it was invented for in 1937 by B. C.
