Frequently Asked Questions (FAQ)
💡 Why Highlight Holidays and Special Dates?
Every project encounters dates that deserve special attention — national or local holidays, company shutdowns, or milestone events. Highlighting these in your Gantt chart ensures your timeline, task durations, and dependencies stay accurate.
By using Highlight Day as Holiday, you mark specific days as non-working, allowing Instagantt to automatically recalculate schedules and keep your project end date intact. Alternatively, Highlight Day lets you mark a date visually (in a different color) without turning it into a non-working day — perfect for events that matter but don’t interrupt work.
📅 Example: Use Highlight Day as Holiday for national holidays like Christmas or Independence Day, and Highlight Day for reminders such as “Sprint Review” or “Product Launch.”
⚙️ How to Highlight a Day or Holiday
Adding or modifying highlighted dates in Instagantt is quick and intuitive:
Right-click on the Gantt chart header (the date area at the top).
From the menu, choose either:
Highlight Day as Holiday → marks the date as non-working, affecting task durations and dependencies.
Highlight Day → simply changes the date color for visual reference, keeping it as a working day.
To edit or remove a highlighted date, hover over it in the Gantt chart header. You’ll see:
Two arrows (one on each side) to adjust the range — drag them to make the highlighted period longer or shorter.
A trash bin icon to delete the highlighted date.
⚠️ Tip: After adding a holiday, review your task durations and dependencies. Instagantt automatically shortens tasks if needed to preserve your project’s end date and prevent scheduling conflicts.
