# Calendars {% hint style="info" %} **Who can use this feature?** Admin users can create, edit and archive the library of available Calendars. *** Task Owners, Assignees and Admins can change the Calendar allocated to their Tasks. {% endhint %} Calendars define your project’s working and non-working days. Task durations are based only on the working days set in the assigned Calendar, so Tasks won’t be scheduled on non-working days. ## Creating Calendars *** Create a custom Calendar to set specific working and non-working days that match your project’s schedule.
#### **To create a Calendar:** * Click your Project Title in the top left, then select `Project Assets` * Select `Calendars` from the menu * Click * Add a name and choose a colour to represent the Calendar * Pick your base Working Days * Click specific days on the Calendar to mark them as `Working` or `Non-Working` exceptions * Optionally, * Click `Done` once you're finished editing * The Calendar is added to the library of Calendars the team can assign to their Tasks See also: Group Calendars
Aphex provided Calendars | Name | Working Days | | --------- | -------------------------------------------------------------- | | Five Day | Monday, Tuesday, Wednesday, Thursday, Friday | | Six Day | Monday, Tuesday, Wednesday, Thursday, Friday, Saturday | | Seven Day | Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday |
Project Default Calendar * The default Calendar will be applied to all New Tasks created in the Project * If you change the default later, it won’t affect existing Tasks, they’ll stay on the calendar they were originally assigned
Non-Working Days Adding non-working days to a Calendar will automatically prevent tasks from being scheduled on those days. You can create multiple calendars with different non-working patterns to suit your project.
## Edit an existing Calendar *** You can edit an existing Calendar to update working days, non-working days, change its name or colour. #### To edit a Calendar: * Click your Project Title in the top left, then select `Project Assets` * Select `Calendars` from the menu * Hover over the existing Calendar * Click then select `Edit` * If the Calendar is already in use, select whether to apply changes to existing Tasks or keep their current dates unchanged
Editing a Calendar in use Making changes and saving a Calendar that is in use generates a prompt with the following options: | Prompt | Function | Exceptions | | ---------------------------------------- | ----------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ | | Save and hold dates on existing Tasks | The edited calendar will not be applied to any existing Tasks | Making any changes to the start date, end date or duration of a Task will apply the updated calendar to the Task | | Save and force reschedule existing Tasks | The edited calendar will be applied to all future planned tasks and Tasks with days in progress | The edited calendar will not automatically be applied to any Tasks that have finished (no working days in progress or in the future) |
## Assigning Calendars to Tasks *** Assigning a Calendar to a Task sets its working days and controls when it can start or finish.
#### **To update the Calendar on a Task:** * On the Gantt, navigate to the column picker and toggle on `Calendar` * Click a cell in the column to add a Calendar to the Task from the dropdown * See the non-working days appear with reduced opacity on the Task Bar ![](https://2273109354-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLu0mYklsCTm7XQm3ZGqv%2Fuploads%2Fui9DtobcNP8kO1Uhj29e%2FGroup%20143724558.svg?alt=media\&token=95caa9d7-8c8b-479b-8c1e-ce4319c9ed2f) See also: Bulk Edits
