# Applying recurrence

As outlined in the *Recurrence* overview, PADS4 Scheduler allows you to define **repetitive schedules** using customizable recurrence patterns. Recurrence can be applied to **Simple**, **Playlist**, and **Advanced** schedules and ensures that content is shown repeatedly over defined intervals without needing to create duplicate schedules.

***

## Accessing the Recurrence Settings

You can apply recurrence in two ways:

* During schedule creation in the **Schedule Wizard** by clicking the **Recurrence** button.
* From the **Ribbon Bar** by selecting the **Recurrence** function (see the *Recurrence* topic for details).

Once accessed, the **Recurrence Settings** window will appear.

***

## Recurrence Settings Window

This window is divided into four key sections:

1. **Period**
2. **Type**
3. **Within One Day**
4. **Description**

Each is described below.

***

### 1. Period: Defining the Time Span

In this section, you set the overall **start and end conditions** of the recurrence pattern.

* **Start Date**: Specifies when the recurrence begins.
* **End Options**:
  * **By End Date**: Ends on a specific date.
  * **By Number of Occurrences**: Ends after a set number of repeats.
  * **No End Date**: Repeats indefinitely.

***

### 2. Type: Defining the Recurrence Pattern

PADS4 Scheduler offers **four recurrence types**, each with flexible configuration options:

#### **Daily**

* Repeats every *X* number of days
* Optionally, restrict to weekdays only

#### **Weekly**

* Select specific days of the week (e.g., Mon, Wed, Fri)
* Choose the repeat interval in weeks (e.g., every 2 weeks)

#### **Monthly**

* Two configuration options:
  * **By Date**: e.g., every 15th of the month
  * **By Pattern**: e.g., *Second Tuesday* of every 3 months
    * Choose: `first`, `second`, `third`, `fourth`, `last`
    * Then select: `day`, `weekday`, `weekend day`, or a specific day (e.g., Monday)

#### **Yearly**

* Similar to Monthly, with two options:
  * **By Date**: e.g., March 23rd every year
  * **By Pattern**: e.g., *Last Friday* of April
    * Define the ordinal, weekday, and month

***

### 3. Within One Day: Time-Based Repetition

This section defines **when during a single day** the content should be displayed:

* **From / Until**: Set the daily time window (e.g., 08:00–18:00)

You can also specify finer granularity within that window:

* **Uninterrupted**: Show continuously within the time window
* **Several minutes per hour**
* **Several minutes per X minutes**

> This is useful when you want content to appear only at intervals, such as 10 minutes every hour.

***

### 4. Description: Review the Recurrence Summary

The **Description** section dynamically updates as you adjust the settings. It provides a **readable summary** of the recurrence pattern for easy verification.

Example output:\
*“Occurs every Monday and Wednesday, from 08:00 to 18:00, starting on March 1st, ending after 10 occurrences.”*
