# Schedule Trigger

### Overview

The Schedule Trigger (**Scheduler**) allows you to execute workflows automatically based on time. Instead of triggering actions manually, you can schedule workflows to run **once at a specific time** or **repeatedly at fixed intervals**.

This is ideal for automation use cases such as recurring on-chain actions, periodic data fetches, routine fund transfers, or timed smart contract interactions.

***

### What the Scheduler Does

The Scheduler acts as a **time-based trigger** that starts your workflow execution according to predefined rules. Once configured, it runs independently without manual intervention.

Key capabilities include:

* Delayed execution (run after a set duration)
* One-time scheduled runs
* Recurring executions at regular intervals
* Minute, hour, or day-level granularity

***

### Configuration Options

#### 1. Schedule Type

Choose how you want to define the execution time:

* **Schedule In**\
  Runs the workflow after a specified duration (e.g., after 10 minutes).
* **Schedule At**\
  Runs the workflow at an exact date and time.

***

#### 2. When to Run

Defines whether the workflow executes once or repeatedly:

* **Run Once**\
  Executes the workflow a single time based on the schedule.
* **Repeat Every**\
  Executes the workflow repeatedly at the defined interval.

***

#### 3. Run In (Value)

Specifies the numeric duration before execution (used with **Schedule In**).

Example:

* Value: <mark style="color:$primary;">10</mark>
* Unit: <mark style="color:$primary;">Minutes</mark>
* Result: Workflow runs after 10 minutes

***

#### 4. Unit

Defines the time unit for scheduling:

* Minutes
* Hours
* Days

***

#### 5. Schedule Preview

Displays a human-readable summary of when the workflow will run.\
This helps verify your configuration before activating the schedule.

Example:

> **Run once in 10 minutes**

***

### Common Use Cases

* **Recurring blockchain monitoring**
* **Delayed smart contract execution**
* **Automated periodic fund transfers**
* **Scheduled data reads or API calls**
* **Time-based notifications or alerts**

***

### Example Workflow

**Scenario:** Run a workflow every 10 minutes to fetch on-chain data.

* Schedule Type: `Schedule In`
* When to Run: `Repeat Every`
* Run In: `10`
* Unit: `Minutes`

Result: The workflow executes automatically every 10 minutes.
