Recently I designed a calendar puzzle with 10 tetris-like pieces. When you place all the puzzle pieces on the board, three squares/rhombuses are still open and together they form a date. Can you arrange the puzzle pieces in such a way that it shows todays date?

- xyzzy_plugh 1y agoThis is quite clever.
- teraflop 1y agoVery cool! Unfortunately the interactive demo doesn't work for me (Firefox 143.0.4 on Windows): > Uncaught TypeError: can't access property "inverse", this.puzzlemat.getScreenCTM() is null
- peterpuzzle 1y agoFixed. On some puzzle pieces there is still a small offset in Firefox, but I can't find the reason...
- rawling 1y agoCan you arrange them to make dates that don't exist, or is it designed so you can't?
- peterpuzzle 1y agoYou can arrange the puzzle pieces to make dates that don't exist, like Monday February 31. Actually there may be "impossible" dates, because I didn't check for them, but I think all combinations of days of the week, day of the month and month are possible.
- malnourish 1y agoI love this. Do you ship to the US?
- peterpuzzle 1y agoYes, I do ship to the US.
- ewheeler 1y agoFun! Very similar to https://www.dragonfjord.com/product/a-puzzle-a-day/ https://www.dragonfjord.com/product/a-puzzle-a-day/
- jpsouth 1y agoI got this for my mother and she loves it, but it’s bloody hard some days! Great bit of kit though for any puzzle lovers.
- peterpuzzle 1y agoI sometimes advise people not to focus on today's date, but a date in the following week. Then you have more time to find a solution!
- peterpuzzle 1y agoYou are right. This puzzle started my search into this type of puzzle. But in the end my puzzle is harder, because it also contains the day of the week and has the most "irregular" puzzle pieces possible.
