Adding an event to your timeline

Events are the key components of any Preceden timeline. Events can represent anything from an upcoming project milestone to the building of the pyramids and anything in between.

To add an event, click the Add Event button or press ⌘+A on Macs / Control + A on Windows.

Here's an overview of each of the options along with a description of how those settings impact the appearance of the event:

Name

Every event must have a name to display on the timeline.

The position of the event name depends on several factors:

  • If an event has a start date only, then its name will always be placed to the right of the symbol
  • If an event has a start date and an end date, then its name will be placed within the color bar if the name fits, otherwise the name will be placed to the right of the bar. You can change this behavior under the timeline's settings to have Preceden always display the name to the right of the colored bar.

If you have autocomplete enabled (which it is by default for students and teachers), Preceden will search publicly shared timelines as you type for similarly named events. It will then show you the dates for those events which you can then click to autocomplete the name and dates for your event:

You can disable or enable event name autocomplete from your account page.

Color Picker

The color picker allows you to choose the color of the event:

The color is applied as follows (see the screenshot in the Name section above for reference):

  • If an event has a start date only, then the symbol and the event name will use the event's color
  • If an event has a start date and an end date and the name is displayed within the bar, then the bar will use the event's color and the event name will be white
  • If an event has a start date and an end date and the name is displayed to the right of the bar, then the bar and the name will use the event's color

Milestone

A milestone represents an important event that you want to stand out on your timeline.

When you check the milestone setting, you'll only be able to specify a start date for the event and the event will be displayed as a vertical line that spans the entire height of the timeline:

Preview

The preview field gives you an idea of what the event will look like with the given name and color if you specify a start and an end date and the name is displayed within the colored bar. See the Name section above for an explanation of the situations where the name is not displayed within the colored bar.

Symbol

The symbol is displayed to the left of the event name when the event only has a start date:

If you specify an end date for your event, the symbol will be ignored because the event will be displayed as a colored bar.

Layer

When your timeline contains multiple layers (by adding them via the Add Layer link above your timeline) then you can use this dropdown to specify which layer you want the event to be added to.

Start Date

Every event must have a start date to let Preceden know when the event occurred. You can use the date picker or type in a date in one of the many  date formats that Preceden supports.

If your event contains multiple events and you you've enabled dependencies (via Settings > Dependencies), you'll also be presented with a link to make this event start when another one ends which will let you select an existing event on the timeline. Learn more about dependencies.

End Date

Similar to the start date, the end date specifies when the event ends. This field is optional so if the only has one date associated with it, you can leave this field blank. You can specify durations for the end date such as "1 week", "1 month 5 days" etc. Also note that both the start date end the end date are inclusive.

Approximate dates

For events whose dates are approximate, you can use the Approximate setting to the right of both the start and end date to inform Preceden.

For events that contain a start and an end date, being marked as approximate will display cause the bar to fade in (if the start date is approximate) and fade out (if the end date is approximate):

The approximate settings have no impact on events that contain only a start date.

Notes

The final field is for any additional notes about the event.

These notes will be displayed when you hover your cursor over the event on your timeline as well as in the list of events below your timeline.

You can add images as well as links to the notes. Notes also support Markdown formatting.
