Undated Horizontal Erasable Wall Calendar helps you stay focused on what's coming down the road without overwhelming yourself. Undated layout lets you start with any month, any year and never fall behind. One side offers a 30-day undated format so you can plan your schedule for the whole month, every month in the 3-3/16" x 2-1/8" daily blocks. This planner is reversible with other side featuring an erasable, 60-day undated calendar with 1-9/16" x 2-1/16" daily blocks for flexible scheduling each month. Both formats include notes space for next month's plans. Bright white background allows easier viewing and reading. The planner is erasable to give you ultimate flexibility in your scheduling on the easy write-on/wipe-off surface. Use with wet-erase markers (sold separately). Undated calendars are printed in blue on quality paper containing post-consumer waste.
