Hello puzzly friends!

Today is indeed your lucky day, as I have a second puzzle to share with you, courtesy of constructors Michael Hanko and George Barany!

They’re hosting a puzzle contest and asked me to help spread the word to my fellow puzzle enthusiasts.

The challenge before you? Solve the crossword below, titled Calendar Arithmetic, and complete both the grid and the bonus message (a timely warning!) at the bottom of the grid.

Once you’ve printed and solved the puzzle, either photograph or scan the completed grid.

Send it AND the timely warning to barany@umn.edu for a chance to win a prize, like puzzle books or complimentary custom puzzles to be worked out with the constructors!

Submit your entry by the vernal equinox for your chance to win: Friday, March 20, 2926, 9:46 AM. (Okay, just checked, and they’re offering a grace period, as long as you get the puzzle in by midnight on Sunday, March 22nd.)

Good luck, and happy puzzling!
