Who can do this

Admins and Project Managers can manage the work calendar.

Where to find the work calendar

The work calendar settings live in the Schedule tab for a project. Look for Work Calendar or Schedule Settings near the top of the page.

Steps to add a holiday

  1. 1Open the project's Schedule tab.
  2. 2Click Work Calendar (or Schedule Settings).
  3. 3Click Add Holiday or Add Non-Working Day.
  4. 4Select the date (or a date range for multi-day closures).
  5. 5Give it a label, such as "Independence Day" or "Winter Shutdown."
  6. 6Save the calendar change.
  7. 7Click Recalculate Schedule so downstream task dates update to account for the added non-working day.

How this affects dependent tasks

Once a date is marked as non-working, Doxlair skips it when calculating task durations and dependency dates. Any task whose duration spans that date — or whose start depends on a task that does — will shift accordingly after you recalculate.

Tip

Add known holidays and planned shutdowns as early as possible in a project. Adding them after a schedule is already built means dates will shift, so always recalculate immediately afterward.
