Add an Event to Your Timeline
Events are the key component 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 above your timeline or press the letter 'a' on your keyboard:
Below is an overview of each of the options along with a description of how those settings impact the appearance of the event.
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 icon.
- 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 turned on (which it is by default for students and teachers), Preceden will search publicly shared timelines as you name your event. It will then show you the dates for similar events, which you can click to autocomplete the name and dates for your event:
You can enable or disabled autocompletion from your Account page.
The color picker allows you to choose the color of the event (click on the color square):
You can also use the custom color picker at the bottom to choose a color not on the palette, just click on the square under Custom Color Picker.
The icon 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 icon will only appear when you hover over the event and in the event list below the timeline, since the event will be displayed as a colored bar.
You can also request additional icons: Request a New Icon.
When your timeline contains multiple layers, you can use this dropdown to specify which layer you want the event to be added to:
To add a layer, click the Add Layer link above the timeline (see Layers for more details).
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 you have multiple events on the same day, you can enter a time after the date to organize the events in their proper order (E.g., November 23, 2019 7:30 am). When two events start at the same time they will be ordered alphabetically. Therefore, if you want one event to come before the other, name them accordingly.
For events where you don't know the exact dates, you can use the Approximate checkbox to the right of the start and/or end date to tell Preceden:
For events that contain a start and an end date, being marked as approximate will cause the color bar to fade in (if the start date is approximate) and fade out (if the end date is approximate):
Marking an event that only has a start date as approximate has no impact on how the event is displayed.
Similar to the start date, the end date specifies when the event ends. This field is optional, so if the event 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 and the end date are inclusive.
This 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.

Preceden also supports some less common options for events, listed below. You can see these options by clicking the Show Options button:
Make this event a 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 and the event will be displayed as a vertical line that spans the full height of the timeline:
Make this event start when another event ends
Hide this event's name on the timeline
It will appear like this if there is a start and end date:
To unhide the names, simply click on the icon or color bar and the options will appear again.
Include the amount of time between this event and other events
You can have Preceden include the time between this event and others using this feature.

Duplicate an Event
If you want to add the same event that already exists, you can click on the event name. In the bottom, right hand corner of the window you will see the Duplicate Event link. Click on it and the duplicate event will automatically be added to your timeline.
