Whether you are writing a novel, managing a project, or researching a legal case, Aeon Timeline 2 has the tools to help you map the past and plan the future.


A timeline is composed of a series of events: an occurrence that happens at a particular time for a given duration. Depending on your project needs, these events may represent plot points in a novel, planned future tasks in a project, or known events in a legal case or historical research.

Events are displayed graphically on the timeline with a title, date, and duration, but you can associate a lot of additional meta-data with an event, including colors, tags (keywords), notes, completion status, and other user-definable fields.

Entities and Relationships

Aeon Timeline is not just about events. You can add other items to your timeline such as people, places, projects, resources, and story arcs – known collectively as Entities – and create relationships between events and those entities to mark which characters were present at an event, or which employees are responsible for a task.

If you give an entity a date of birth, Aeon Timeline will calculate that entity’s age for each event they are associated with, allowing you to quickly see someone’s age at important events in their life.

Group by Type

As your timeline grows in size and complexity, it can be useful to separate events into groups rather than show them interspersed throughout other events. In Aeon Timeline 2, you can select which entity type to group by (e.g. Person, Project, Arc, Location). Events may appear in multiple groups if they have relationships with several different entities.

This allows you to see tasks divided by project or employee, or divide events in a fiction novel by arc, character, or place, making it easy to focus on events associated with an individual entity.

If an entity is configured with a birth date, their age will be shown along the top of the group.


Dependencies allow you to calculate the date of an event based on an offset from the start or end of another event (e.g. Event B = end of Event A + 10 days). This ties the two events together in time so that when you move one event, the other will automatically follow. An event can have multiple dependencies, in which case its start date will be set to the latest calculated date.

Dependencies allow you to ensure pre-requisites are met in a project (i.e. a task that cannot start until an earlier one has completed), or tie together events in a fiction story that require a fixed offset (e.g. a birth must occur 9 months after conception).

Link to Images/Research

Aeon Timeline allows you to link your events with images and external documents and websites, allowing you to link your chronological view with your research and supporting documentation.

Linked images can be shown directly on the timeline, and clicking on linked files will open them in their appropriate application (or directly within Aeon Timeline via Quicklook on the Mac).
