Help honor and empower Wounded Warriors by choosing this erasable, reversible calendar. A portion of the proceeds from the sale of this product will be donated to the nonprofit Wounded Warrior Project. The Wounded Warrior Project serves veterans and service members who incurred a physical or mental injury, illness, or wound, related to their military service on or after Sept. 11, 2001. Both sides offer a write-on/wipe-off surface for easy updates and range 12 months from January to December with numbered weeks, federal holidays in red and unruled daily blocks. One side features a vertical format with 13/16 x 1-3/16" blocks. The other side has a horizontal format with 15/16" x 1" blocks so you can easily plan by the quarter.
