You can also change the display to show the time, day of the week, and date in large numbers. Recommended by a care manager, I purchased this for my mother's care on Rakuten for 3,630 yen. The following is a product description: Introducing "Koyomin," a digital calendar & radio-controlled clock developed from the voices of people working in nursing care facilities! Easy to use for seniors and their families. As people age, they may not be able to remember a large amount of information, and their schedule management becomes simplified, such as "just the date" or "just the day of the week." They may also become confused about the sense of time and feel anxious about their memory, repeatedly asking family members or caregivers for the date, day of the week, and time. To make it easy for seniors and those around them to use and to facilitate smooth communication, an ultra-simple digital radio-controlled clock that only displays the date and time has been created. With a single button, you can easily switch to the time display, and it can be placed or hung, so you won't have trouble finding a place to put it. Recommended for family care, medical and nursing care facilities, and as a gift for Mother's Day, Father's Day, or Respect for the Aged Day. Useful for managing medication and meals.
