I bought this clock for my elderly mother who is in a nursing home and has no idea what day, week, or month it is.  The clock works great for this purpose, except the digits on the bottom with the day of the month having a slash through the zero which makes it look like an 8.  It is no necessary to use that type of zero, since there are no letters in that section and the zeros in the time do not contain slashes.  For an elderly person, it is confusing.
