====== Calendar management ======

Each activity in Tilos360 is associated with a calendar.  
By default, four calendars are available:

  * the **“Non-Stop calendar”**
  * the **“5 days per week, 7 hours per day calendar”**
  * the **“5 days per week, 8 hours per day calendar”**
  * the **“Milestone calendar”**, which cannot be edited

Calendars can be accessed using the navigation button  
{{:fr:parametrages:2026-03-11_18h51_10.png?30|}}

Calendars are based on the following elements:

  * First, **''periods''** (generally weeks).
  * Each day of a period is associated with a **''day definition''**, which defines the number of working hours.
  * Day definitions consist of one or several **''working time ranges''**.

These elements are configured in this interface.

===== Day definitions =====

For each type of day (Working day, bad weather, holidays, etc.),  
a day definition must be created and assigned one or more working time ranges.

----

===== Periods =====

You must then define a period composed of the previously defined days.  
A period consists of **a minimum of 1 day and a maximum of 7 days**.

Choose the number of days for the period and assign each day
to the desired **day definitions**.

===== Calendar =====

You can then define the default project calendar by creating
or editing a calendar.

Add the previously created periods.

A period remains active **until another period interrupts it**.

----

===== Exceptions =====

You can add exceptions to your calendar:

  * by manually creating exceptions
  * by importing a calendar in **.ics format** using the **Import** button

To create an exception, you must first define a day in **Day definitions**
that corresponds to the exception.  
You can then assign it to your calendar.
