Project and app settings
Last updated 30 September 2026
Ganttastic has two settings layers. Project settings (the three dot menu beside a project name, then Settings) control that project’s work calendar, date format, and resources. App settings (your avatar, then App Settings) are personal preferences such as theme and display density that follow your account everywhere.
This page covers both: first the Project Settings dialog tab by tab, then the Application Settings dialog.
Two kinds of settings
Project settings live with each project and affect everyone who opens it: the work calendar, date format, Gantt bar labels, and the resource list. App settings are yours alone: theme, contrast, and density. App settings are stored on your account, so they apply on every device you sign in from.
Open project settings
- In the sidebar, click the ... menu beside the project name, or right-click the project row.
- Choose Settings. The Project Settings dialog opens with three tabs: Display, Work Calendar, and Resources.
If you only have viewer access, the ... menu item reads Settings (View Only) and the dialog opens with every control disabled. In the right-click menu the item reads Settings and is disabled.

Display tab
The Display tab opens by default and has three groups:
- Project Details: a free form Description and a Project Start Date picker. Left unset, the picker shows "Not set (uses earliest task)". The date is for reference only: changing it does not move any task, and the timeline always starts from the earliest task’s start date. To move the plan, move the tasks.
- Display Preferences: Date Format has four options (dd MMM yyyy, the default, which renders as 25 Mar 2026; MM/dd/yyyy; dd/MM/yyyy; yyyy-MM-dd). The chosen format applies across the app and carries into exports and AI generated output. First Day of Week can be any of the seven weekdays; the default is Sunday.
- Gantt Bar Labels: two switches, Show Task Names on Gantt Bar (off by default) and Show Progress on Gantt Bar (on by default).
Work Calendar tab
The Work Calendar tab controls which days work can be scheduled on. Every duration calculation, dependency push, and AI proposed date respects its working days and holidays; see dependencies and milestones.
- Work Schedule: tick the working days of the week (Monday to Friday by default). The Work Hours section below them records your working hours as time blocks. New projects start with none; Add Time Block adds one from 08:00 to 17:00, and each block has a remove button. Work hours do not affect scheduling, which counts whole working days; see how automatic scheduling works.
- Holidays & Non-Working Days: click Add Holiday to add a row named "New Holiday" dated today. Rename it, pick its start and end dates to block out a single date or a range, and remove it with the button beside it. Tasks are not scheduled on those dates. If you set an end date earlier than the start date, the dialog corrects the other date to match.
Resources tab
The Resources tab holds the project’s resource library: the people and teams you can assign to tasks.
- Click Add Resource to add a row.
- Enter a Name, pick a Type (Internal or External are the only options), and optionally fill in Role and Company / Department.
- Remove a row with the X button beside it.
Resources belong to the project, not your account, so add the same person again in each project that needs them. Once saved, they appear in the resource picker of the Task Details panel; see working with tasks.
Save your changes
Nothing commits until you click Save changes at the bottom of the dialog. One click saves your edits from all three tabs at once. The button reads Saving... while the save is on its way, and the dialog stays open until it lands. Click Cancel or close the dialog to discard your edits.
App settings
App settings are personal preferences stored on your account. To open them, click your avatar initial in the sidebar and choose App Settings. The Application Settings dialog appears with three controls:
| Setting | Options | Default |
|---|---|---|
| Theme | Light, Dark, or System (follows your OS) | System |
| High Contrast Mode | On or off | Off |
| Display Density | Comfortable or Compact | Compact |
Changes apply the moment you change a control; Close only dismisses the dialog. Because the settings are stored on your profile, they sync to any device you sign in from.
Compact density makes Gantt rows, day columns, and bars smaller on a computer so more of the plan fits on screen. Phones ignore it and keep the regular size.

Easier to try than to read about.
