I get a little melancholy when the year turns and it's time to take down my calendar. We've spent a 12 months together, after all. Of course we've gotten a little attached! I'm considering buying a perpetual calendar, or one that you use over and over again. The calendars that most interest me catalog years gone by (kind of like an analog version of Timehop) or help you remember birthdays and important events (I could use a little help in that department). If you're into that, too, these calendars will get you through many years ahead.
