# Function schedules

> Schedule function executions in Cognite Data Fusion (CDF).

Function schedules let you run Cognite Functions automatically at defined intervals using cron expressions. Each schedule is linked to a specific function and can include input data that is passed to the function on each execution.

## What function schedules do

A schedule defines when a function should run. You specify a cron expression (for example, every hour or every day at midnight) and optionally provide input data. CDF creates a function call according to the schedule, passing the configured input to the function.

## Managing schedules

* **Create**: Define a new schedule with a cron expression and optional input payload.
* **List**: View all schedules for a function or across your project.
* **Delete**: Remove a schedule to stop automatic executions.
* **Inspect**: Retrieve schedule details including the cron expression and input configuration.

<Info>
  Schedules use standard cron syntax. Ensure your cron expression is valid for your desired execution frequency.

## Use cases

Use schedules for periodic data syncs, recurring reports, cleanup tasks, or any workflow that should run on a fixed interval. Combine schedules with functions to automate data processing without manual invocation.
