Kalendertags

Kalendertags are metadata labels attached to calendar events to categorize and filter entries. They function as lightweight tags that describe topics, projects, participants, locations, or priorities, enabling users to group related events across dates and calendars. Kalendertags are common in personal calendar apps and in collaborative planning platforms, where they help with organization and quick retrieval.

In practice, the concept overlaps with the standard iCalendar mechanism known as categories, which serves a similar purpose across calendar software. A Kalendertag is typically a short, text-based string, and multiple tags can be assigned to a single event. Different systems may implement tagging with varying syntax or storage, but the goal is consistent: provide a searchable, filterable dimension beyond the event title and time.

Usage typically involves adding tags during event creation or editing and then using views or filters to display only events that match one or more tags. This supports project-oriented scheduling, cross-team coordination, and personal task management. Tags can be used to combine or exclude certain topics, and they often appear in search results, calendar dashboards, or synchronized views across devices.

Best practices for Kalendertags include maintaining a controlled vocabulary to reduce synonyms and fragmentation, using consistent naming conventions, and being mindful of privacy and security when tags disclose sensitive information. Interoperability benefits from leveraging standard properties where available (such as categories in ICS) to ensure compatibility across calendar apps and services.
