We can often take the calendar for granted, 1 Jan 2023 apart from different time zones is the same worldwide? Apparently not. Some countries are using multiple calendars!
Take a read for your self:
The people who live in multiple timelines - BBC Future
The Wikipedia page on Calendars also explains the differences.
January, the start of the year. The month we put away the Christmas decorations. We reorganise our Filofax organisers and take down last years wall calendar....
Do you just recycle it, or repurpose it? Or both...
If your wall calendar has images of a place you have fond memories of, then keep those pages and reuse the images on your section dividers or as your dashboard at the front of your organiser.
The map was printed on one side of A3 size paper. With some careful folding and punching some holes in the edge it fits A5, see this earlier post on how to do this: Using A3 paper in A5 size Filofax.
In simple terms with the A3 page in landscape, measure 87mm up from the bottom edge, and then fold the page up along that line, that gets the page to A5 height. Fold the page over at 148mm from the left hand edge, and then back again to the right hand edge. On the bottom section, fold the corner of the flap over at 45 degrees. Punch to fit A5 Filofax.
The map is printed on quite thick glossy paper, so it should last a few years. I also salvaged the 2023 calendar from the back cover!
