To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is a great wall calendar with wipe-off feature. It includes a pen, which wipes off with a damp towel. My only complaint is that the year (2021) is at the very bottom of the poster. Since we work on long term projects that run from one year to the next, we have the current year (2020) hung on the wall next to this calendar (2021). When you look at this calendar next to the 2020 calendar, you have to search for the year to make sure you're looking at the correct calendar. So, I used the marker to write 2021 in the blank spots before January, February, and March start. I'm still glad I purchased, because this is the only brand I could find that was available in July and the correct size. Not sure when other brands (At-A-Glance, etc) come out with their calendars, but we definitely needed ours by July.
We used this large wall calendar for all social events year after year and it works great. The only thing I can't seem to find is fine pointed erasable markers, in assorted colors that work in the boxes. Some write too thick.
