Configure calendars

Working calendars affect how tasks schedule is displayed and calculated.

For example:

• Durations don’t include nonworking days and hours.

• Gantt charts skip nonworking days and hours when setting start dates.

Configure working days and hours

Set the working hours and rest days to reflect your team’s schedule, this setting will be applied to the current Gantt project.

Nonworking hours will be displayed as grey columns on the timeline view:

Configure extra holidays

By default, each Gantt chart has a predefined General calendar that reflects the standard holidays. You can also create custom calendars for different resources to reflect individual holidays.

General (global) Gantt calendar setting

1. From the Calendars setting tab, navigate to the “Extra Holidays” section

2. You’ll notice the current calendar is set to “General”

3. Click on the “+” button to add extra holidays to “General” calendar

4. Click “Update” to save changes

Please note that the default General calendar name can’t be edited.

Create custom calendars

You can create custom resource calendars to register non-standard extra holidays (i.e. vacation days or medical leaves) for more accurate scheduling.

1. Click on the “plus” button to add extra holidays as usual

2. Select the option “Add new calendar”

   

3. Define the custom calendar name

4. Add the respective holidays to the new custom calendar

5. You can switch between calendars and edit or remove them from the dropdown menu

Relation between working days and duration units

Please note working days affects the meaning of duration units.

The table below shows the number of days per 1 duration unit in each case of the number of working days. Please note extra holidays do NOT affect the meaning of the duration units.

One quarter equals the number of days in 3 months. And one year equals the number of days in 12 months.

Example

Your Gantt chart has 5 working days, including Monday, Tuesday, Wednesday, Thursday, and Friday:

In this case,

• 8 hours equals 1 day

• 1 week equals 5 days

• 1 month equals 20 days

• 1 quarter equals 60 days (20 days * 3 months)

• 1 year equals 240 days (20 days * 12 months)
