Sign up for 2018 calendar


The Puzzle cube calendar is a marvel of paper engineering, but it is very time consuming to update every year with the new dates.

Please enter your name and email below to let me know that you would be interested in purchasing the new 2018 calendar once it is ready. If enough people are interested I will prepare the file and notify you when it is available for download.

Although I do hope that you will follow up and make the purchase when the time comes, this is not a commitment on your part. Signing up no in no way obligates you to buy the calendar later — but it is important, because if I don’t hear from you I might not make it.
