This rotating pocket calendar can calculate the day of the week for any date within 50 years. The ingeniously simple design dates back over 500 years, before the institution of the Gregorian calendar. Luckily, even leap years are considered in this fascinating device.

Simply spin the brass dial in the marble base until the selected year lines up with the selected month. Locate the date in question and you'll find the correct day of the week above it! An analog device with antiquarian charm that can't be matched by a glowing screen.

Shipping & Returns

Our products ship through a privately owned climate-controlled warehouse in San Diego, California.

We offer a variety of shipping methods from budget-friendly to price-doesn’t-matter. You can compare estimated costs and transit times once you begin the checkout process and enter your shipping address. Carrier options may vary based on your destination.

We strive to pack and ship all items within 24 hours of each order (Monday through Friday). However, we are a small team so during peak holiday season we kindly ask that you allow 3-5 days for your items to be sent on their way. Every box shipped from Art of Play is expertly packed by actual human beings (you can see their names written on your package slip). Everyone in our warehouse is paid a fair wage and treated with respect.

Return Policy

We will gladly offer a refund or store credit in exchange for any items returned within 30 days of the original order, as long as the items are still sealed in new condition. We cannot accept returns of opened or used items. Return shipping is the responsibility of the customer.
