Calendar Puzzle

A browser version of the physical calendar puzzle: eight polyomino-style pieces must cover a 43-cell board so that only the cells for the current month and day stay visible. Every date has a new layout goal. A live arena runs timed rounds every five minutes with identical pieces for all players, and solutions for all 366 dates are published.
