Perpetual Calendar Ring

My wife designed this ring for our 3 year old daughter’s Grapat perpetual calendar so she could keep track of the days of the month. She adds a wool ball each morning. It’s helped her conceptualize how long each month is, and even look forward to exciting events (for example, the green ball is the due date for her baby sister, arriving any day!). 

  • The material is 9mm (1/2") Baltic Birch Ply. 
  • We're not able to offer the 1" felt balls but you can find the ones we ordered here.
  • There are 31 spots for the balls.
  • My favorite thing about the ring is that it makes it possible to easily move the calendar around the table.
