How to Display Holidays on the Gantt Chart

Introduction

Easy Gantt allows you to visually display holidays directly on the timeline. Holidays appear in the same style as weekends—as gray columns—helping you plan accurately by avoiding non-working days. This guide shows how to enable holiday visibility and manage related settings.

Target Audience

  • User

Prerequisites

  • Easy Gantt module enabled
  • Access to Gantt settings
  • User profile with a working time calendar assigned

Steps

1. Open Gantt Settings

  • Go to your project or global Easy Gantt view
  • Click the Settings icon in the upper-right corner

2. Enable Holiday Display

  • In settings, find the checkbox for Show holidays
  • Tick the checkbox
  • Click Update settings to apply the change

Holidays will now appear as gray columns, similar to weekends, on your Gantt timeline. Weekends are always visible; holidays appear based on your settings.

3. Understand Where Holidays Come From

Holidays and working days are based on the working time calendar of the logged-in user, not the task assignee. This means:

  • Each user sees holidays based on their own calendar
  • Assignees may have different non-working days

Managing Working Time Calendars

Set Calendar in User Profile

  • Go to the user’s profile
  • Open the Working time tab
  • Select or modify the assigned calendar

Default Calendar for New Users

  • New users are automatically assigned the default working time calendar
  • To update the default template:
    • Go to Global menu → Administration → Working time - templates

If you update the default calendar template, it will not affect users who were already created. You must manually reset their calendars.

Reset Calendars for Existing Users

  • Right-click and choose Change working time calendar to
  • Apply the updated template

Conclusion

Displaying holidays on the Gantt chart helps you avoid scheduling tasks on non-working days. With a few clicks in settings, you can align your timeline with real-world availability based on each user's working time calendar. For consistent scheduling, make sure users have updated calendar templates.
