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.

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
