'What day is it today?' Answered at a glance. The Large Display Calendar Radio Clock 'CL400' clearly shows the date and day of the week.

GDT Co., Ltd. (located in Kawaguchi City, Saitama Prefecture) has released the 'sology Large Display Calendar Radio Clock CL400,' designed to display the date and day of the week in large font.

This wall clock was developed focusing on the concerns of elderly individuals who repeatedly ask 'What day is it today?' or 'What day of the week is it?'

It combines an easy-to-read analog clock with a diameter of 30.5 cm and a large digital date display, offering peace of mind to family members living apart. The radio-controlled clock function automatically corrects not only the time but also the date. It requires no manual setting, ensuring the correct date is displayed until your next visit home.

It is suitable for use in senior homes, dementia care, hospitals, nursing facilities, offices, and schools.

■ Development Background
The product was inspired by casual conversations with elderly parents living apart. Being asked the same questions, such as 'What day was it today?' or 'What day of the week is it?' during phone calls or visits, led to the idea that a clock showing both date and day of the week could provide reassurance.
With Japan's aging population, more people feel anxious about keeping track of dates. Therefore, sology developed the CL400 not just to 'tell time,' but to serve as a clock that helps users 'confirm today.'

■ Product Features
1. Highly Visible Date and Day of the Week
This clock combines an analog clock with a large digital display for seniors. Showing the date and day of the week prominently supports their sense of date and time. The highly visible text is easy to read from a distance, making it suitable for elderly individuals, dementia care, and nursing facilities.

2. Simple Setup: Automatic Accurate Date via Radio Waves
The clock receives standard radio waves. Since both time and date are adjusted automatically, it minimizes setup hassle and can be used reliably after battery replacement. Families living far away do not need to worry if the clock is running slow or if the date setting is correct. It is also recommended as a gift or monitoring tool for elderly parents.

3. Large 30.5 cm Size for Easy Reading from Afar
With a large diameter of approximately 30.5 cm, this calendar clock is highly visible from living rooms or bedrooms. Users can check the time, date, and day of the week all at once without having to check a physical calendar. The simple, calm design naturally fits homes, hospitals, nursing facilities, and day care centers.

4. Suitable for Public Facilities as Well
Creating an environment where dates and days of the week are easy to confirm is highly regarded in dementia care. The clock helps alleviate anxiety about losing track of dates and is suitable for elderly care homes, hospitals, and rehabilitation facilities. It is also recommended for schools and offices where date checking is frequently needed.

■ Developer Comment
'We developed this clock hoping that confirming today's date and day of the week, in addition to the time, will bring peace of mind to elderly individuals and their families. We would be delighted if it is chosen as a gift for parents living apart.'
