We just got this calendar yesterday afternoon, and my mom has asked me like 10 since last night what this means. How would I know? I learned it almost 10 years ago and haven't used it since.

Okay, 10 times is a tad exaggeration, hehe, but a few times in an evening and again this morning feels like it. I need an answer before I yell into her face, "I DON'T KNOW!!!!!"

Yes, I've answered that I don't know each time she asked me since last night.
Does anyone (Ibby?) know what this character means?
