Dementia Clock Buying Guide

Digital VS Analogue

Type of Clock
  • Many have a bright backlit display that reduces chance of clock going unnoticed
  • Easier to read due to backlit display and can also be viewed in the dark
  • Multi-displays allow information shown to be changed depending on degree of impairment

Automatic/Perpetual Calendars

What are they?

Perpetual calendar clocks are clocks that do not need manually adjusting for irregular months and years. If a clock has a perpetual calendar the date information will always be correct.

If the clock doesn't have a perpetual calendar then the date will need manually correcting on the 1st day after any month with 30 days (March 1st, May 1st, July 1st, October 1st, December 1st)

Note: This doesn't mean the clock will automatically adjust for daylight savings (that's radio controlled, explained below)

Radio Controlled Clocks
