Calendreco™ is a sustainable perpetual wall calendar that combines innovation, modern appearance, simplicity, and eco-friendly materials and fabrication.

The calendar is composed of one oversized board with the month’s numbers (1 - 31) and three additional headers with different weekday combinations. Depending on the month, the corresponding header is placed in front of the board to indicate the date. With one simple adjustment every month, the calendar can be used year after year.
