In project management, knowing when your team works is as important as what they do. Gaps in timelines, weekends, and non‑standard schedules can all impact delivery dates and resource planning. With Instagantt’s Custom Working Days setting, you create a schedule that reflects your team’s real working pattern — giving you more accurate timelines, clearer workload planning, and fewer surprises.
By default, many tools assume a standard Monday‑to‑Friday schedule. But your team might have different patterns — like four‑day weeks, shift work, or weekend availability. Setting custom working days ensures that every task’s duration, timeline and workload reflect actual working time, not just calendar time. This means:
Using Custom Working Days aligns your project schedule with your team’s actual availability — delivering more predictable and efficient project execution.
Setting your working days in Instagantt is quick and straightforward:
✅ Tip: If you have a mix of full‑week teams and part‑week schedules (e.g., 4‑day workweek or shift work), create separate projects or folders and apply custom working-day settings to each.

Once custom working days are active, several aspects of your schedule adjust:
-> Task durations will count only the selected working days, so deadlines reflect real work time, not just calendar days.
-> The visual timeline in your Gantt chart will skip non‑working days and align bars accordingly.
-> Workload calculations, resource allocations and time‑off simulations respond more accurately because they know which days count as work.
-> If you switch working‑day settings mid‑project, the Gantt chart will update to show the new pattern — so you can see how changes affect delivery.
By reflecting your real working pattern, customizing Working Days helps you build more reliable timelines and coordinate tasks when team availability doesn’t follow standard calendar patterns.
Customizing Working Days in Instagantt lets you align your schedule to how your team actually works — not how a calendar assumes they work. By defining the right working days, your project planning, Gantt chart timelines and workload distribution become far more accurate and transparent.
