I haven't bought one yet, though as I work in a place that sells calendars, I plan to pick one up tomorrow. I use Rainlendar on my computer usually, but I think having a proper calendar would be useful next year. Probably just going to get something plain with plenty of room to write in things for each day, rather than some box I have to try in vain to write "Day trip to Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch" in.
