That Mayan calendar's no big thing.  Now, the Gallifreyan calendar on the other hand ...

Let's say you're a time traveler.  It's not easy to keep your days straight when your tomorrow could be last week.  No, what you need is a calendar that takes the non-linear patron into account.  Well, good news, friend, because just such an item has found its way onto the market!

Illustrator Russell Walks has crafted a special, 7500 year perpetual calendar.  Any day of the week between 1600 and 9999 A.D. is at your fingertips.  Plus you get a host of great Doctor Who art and quotes from the show.

Best of all, though, is that the background is a depiction of the South Pole's night sky on November 23rd, 1963, aka the first night Doctor Who ever aired.  Take a look:

Not too shabby and, best of all, it's something you can actually buy, for $30 no less!  Not a bad deal for all of time and space.
