AEON TIMELINE DISCOUNT SERIES

To provide an example, consider an event that begins on 1 January 2021 and lasts for three months. There is an ambiguity in the way we naturally talk about dates, and a precise mathematical representation of the date themselves. If the month is not specified, it will default to the end of the year.If the day of the month is not specified, it will default to the end of the month.If the time is not specified, it will default to the end of the day (represented as 24:00:00).If the month is not specified, it will default to the beginning of the year.If the day of the month is not specified, it will default to the beginning of the month.If time is not specified, it will default to the beginning of the specified day (represented as 00:00:00).Aeon Timeline treats start and end dates as inclusive, and thus uses the following rules to determine where an item should be displayed when the information is uncertain: How imprecise events are displayedĪlthough more precise date information is not usually displayed on the timeline, the item still needs to be positioned on the timeline relative to other items. 2012 - 2014).Ĭonversely, if you enter 2012 and 2 months, the event precision is now months, and a date value of January - February 2012 will be shown instead. The precision for an item will be determined by the maximum precision of the start date and duration that you enter.įor instance, if you enter a start date of 2012, and a duration of 3 years, Aeon Timeline will only display year information on the timeline. A fiction writer may not need precision down to exact dates/times, in which case making up these values is an unnecessary distraction and clutters up the timeline with unnecessary information.Īeon Timeline allows you to specify varying levels of precision for each item, so you can mix and match events that are specified to the second with events that only contain a year.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.
