An event may take place over an entire day, week, month, or year, so specifying more precise time doesn’t make sense.

An event may be a historic event where the exact date or time is unknown, only an approximate value such as a year (see also, Uncertain dates below).

There are several reasons you may wish to do this: However, it is not always necessary or practical to enter dates to such exacting measurements, so you can instead choose to enter dates with less precision as is appropriate for your data. If you modify an end date to occur before its start date, the change will be rejected.Īeon Timeline handles time down to the second precision.

An item's end date can never be before its start date (i.e.An item start date is preserved when changing the duration or end date, meaning the end date or duration will be recalculated respectively.Item duration will be preserved when changing the start date, which means the end date will be recalculated (thus ensuring an item retains the same duration as it is dragged around the timeline).Once an item has both a date and duration, the three fields (start date, duration, and end date) are always kept in sync to ensure they are mathematically correct.

if you are estimating the length of time a task will take, but don't yet know when it will fit into your schedule) It is even possible for an item to have a duration without yet having any associated dates (e.g.When you are first starting with your timeline, you may wish to brainstorm a series of events or tasks without allocating them specific dates.

You do not need to commit to dates for your items until you are ready: Again, this will be represented as either an absolute or relative date, depending on settings. This represents the date or time when an event ended (or is scheduled to end). If a duration is not specified, it will default to an instantaneous event (i.e. This represents how long an event will last, recorded as a number of years, months, days, etc. Depending on your settings, it will be represented as either an absolute date (e.g. This represents the date or time when an event started (or is scheduled to start).

In the simplest cases, Aeon Timeline tracks three key properties for events: Start Date This article outlines the way dates are stored and represented inside Aeon Timeline, and the various options available to represent events in your timeline as accurately as possible. Unsurprisingly, dates form an intrinsic part of the data you will enter into your timeline.
