Gantt-This

Foreword (by CePeU)

Gantt-This is an Obsidian plugin designed to create arbitrary calendars — the kind most often needed by fantasy
roleplaying nerds — and display them in a Gantt-chart-like view.

There are other plugins available, such as the excellent Chronos Timeline plugin, which would be more than sufficient if
it weren't for the special needs of TTRPG players.

I had an idea for a plugin like this for over a year (and maybe longer) until Altarok and I met on Josh's Obsidian TTRPG
Community Discord server. Altarok mentioned that he was looking for an interesting project to code.

Well, I could hardly believe it, but here we are! :)

Please note that most of the coding work was done by Altarok, leaving me to write a more or less meaningful document.
That should give you an idea of my usefulness... :)

Design Goals

Our goal was to build a zoomable, Gantt-chart-style calendar view so a Game Master can quickly navigate their timeline,
see which events are relevant, and keep a clear overview of their campaign.

Ease of use and a variety of display options were top priorities, alongside the flexibility to create custom calendars
and events for TTRPG purposes.
However, the plugin isn't limited to tabletop games—Altarok even implemented a Mayan calendar just for fun.

Data Safety & Privacy:
The plugin reads your notes and can insert a code block into your active file upon request. It never deletes
data from your vault and makes no network connections.

Next Steps

The plugin is brand new but quite stable. It has moved into wider testing and is already being used in several active
campaigns.
We are continuously adding ideas and suggestions from the community. The main features on our roadmap include:

  • Obsidian Bases support
  • Intraday time support (hours, minutes, and seconds)
  • Additional pre-configured calendars
  • Numerous quality-of-life improvements
  • Your ideas—let us know what you'd like to see!
