Custom / financial weeks in Gantt chart

Question

Is it possible to have custom week numbers instead of the calendar one in weekly Gantt charts?

i.e. instead of week 20, I would like to have week 11.

Answer 1

Ok, that is a nice idea. How would you specify this?

Answer 2

Hello Z.,

With last release v1.2025.3, we can now have this new functionality like:

@startgantt
printscale weekly with week numbering from 11
Project starts the 6th of July 2020
[Task1] requires 2 weeks
then [Task2] requires 3 weeks
@endgantt

Ref.:

• ✨ allow weekly header starting from any number given by user, including negative numbers · Pull Request #2202 · plantuml/plantuml
