Use calendars with Events and Tasks
Choose calendar destinations and understand how calendar identity affects the plan.
Calendar identity is persisted for both Events and Tasks. It controls colour, grouping, visibility, and whether the chosen destination accepts writes.
This is the practical result of the Harmonise planning model: calendars organise the plan, Events reserve dates or time, and Tasks track work with a completion state. For example, a Client review Event and Send revised proposal Task can both belong to Work while behaving differently in the plan.
Assigning a Harmonise Task to a Google, Outlook, Apple, Yahoo, or CalDAV calendar does not create a task in that provider. It remains a Harmonise Task.
On mobile
The Event and Task composer headers show the selected calendar. Choose another visible calendar that Harmonise can edit before selecting Create or Save. Standalone Tasks require an explicit calendar from their creation screen.
A Task linked to an Event uses the Event’s calendar. The composer labels that locked relationship From linked event rather than allowing a conflicting destination.
When linking an existing standalone Task, it must already be in the Event’s calendar. Harmonise rejects a calendar mismatch rather than moving the Task as part of linking. A new Task created from an Event uses that Event’s calendar automatically.
