Please provide dates in Gantt diagrams

Question

I would like to be able to reference dates in Gantt diagrams. Example syntax:

[Prototype design] starts at [2017/08/01]

(Interesting aside: Mermaid supports Gantt diagrams as well: https://knsv.github.io/mermaid/#gant-diagrams7. The syntax in PlantUML looks like it will be much better, though)

Answer 1

Many thanks for your suggestion!

In last release (V8057) you can now define something like:

@startuml
Project starts the 20th of september 2017
[Prototype design] as [TASK1] lasts 13 days
[TASK1] is colored in Lavender/LightBlue
[Prototype completed] happens at [TASK1]'s end
@enduml

We have added support to ISO 8601 standard.
You can also shorten month name to the 3 first characters.

So you can now have:

Project starts the 2017/9/20
Project starts on the 2017-9-20
Project starts the 20th of sep 2017

We do not support "september the 20th, 2017" yet but this will be added.

Many things remain to be done (for example, possibility to close some days like Saturday, Sunday or specific holidays...) This will be added shortly. Stay tuned :-)

About syntax, it's not that easy to find a simple one. Several tries are usually needed to find better ideas.

So do not hesitate to play with our proposal and to make suggestions: nothing is fixed right now, so you can help here!

Thanks again!

@plantuml It´s this function working now? because I try to add this code but appear syntax error:

Project starts the 20th of september 2017
[Prototype design] as [TASK1] lasts 13 days
[TASK1] is colored in Lavender/LightBlue
[Prototype completed] happens at [TASK1]'s end

I have only this error when I want to add a specific month

It should with last version.
At least it does on the online server:

Does it sound good for you ?

I was wondering if it is/will be possible to also use dates to define start/end dates of individual items in a Gantt chart as OP requested.

Setting project dates works, but being able to define items as well would greatly improve the potential use cases to use Gantt for.

You can have:

@startuml
Project starts the 20th of september 2017
[Prototype design] as [TASK1] lasts 13 days
[TASK1] is colored in Lavender/LightBlue
[Prototype completed] happens at [TASK1]'s end
[Prototype test] lasts 10 days and starts 2017/10/10
[Prototype distribution] lasts 3 days and starts the 25th of october 2017

Is this what you are looking for ?

Yes, awesome! I couldn't figure out I need an *and*

Thanks a lot!

is there a way to define the end of a task with a date?
[Prototype test] ends on 2018-10-25
