People with dementia and family carers often use calendars to support time orientation to maintain routine. However, little is known about the use of calendars as a compensatory strategy. This study examines the experience and practicalities of using calendar reminders from the perspective of people with dementia and family carers. Six dyads were recruited and interviewed at home. Interpretative Phenomenological Analysis was used to develop a narrative interpreted from an occupational therapy perspective. The themes were reflected on during two subsequent focus groups. Findings suggested that calendars are used either intensively as external memory records or more casually and randomly for reassurance. The familiarity and location of the calendar and its utility to the person with dementia and carer, all contribute to its efficacy. For carers the experience of supporting calendar reminders encompasses practical, cognitive and emotional effort. There was little awareness amongst participants of electronic assistive technology.
