I LOVE this Perpetual Desk Calendar by Single Chair on Etsy and what they have to say about it:

“I have always liked to collect the little notes that I make to myself. Sometimes I pin them up on a bulletin board or stuff them in a jar. 

The idea here is that the calendar sits on your desk and each day has a card. Each day you can write a note, a little memory, or a quote and then move the card to the back of the stack revealing the next days card. Year after year you can add new notes to each days card, while also reflecting on the notes and messages you left for yourself from years past.

The cards that make up the days are made from vintage timecards, old card catalog cards, library cards, and other odd and ends that I have collected over the years. 

Each perpetual calendar comes with 365 cards (plus about 30 extras) plus the customized cigar box as a holder. 

This idea has basically been a labor of love for me, I thought it was a great idea and wanted to produce it. I love writing in mine and coming across random thoughts and notes so long after I have written them. I find it is a great way to remember moments and I hope that it finds a good home.”
