# Viewing support dates for engine versions in Amazon RDS Extended Support
<a name="extended-support-viewing-support-dates"></a>

You can view information about support dates for engine versions for your Aurora DB clusters or global clusters in Amazon RDS Extended Support by using the AWS CLI or the RDS API. This information can help you plan for upgrades. 

AWS CLI commands and RDS API operations return start and end dates for Aurora standard support and RDS Extended Support. These dates can also be found in the major engine version tables. For more information, see [Amazon Aurora major versions](Aurora.VersionPolicy.Versioning.md#Aurora.VersionPolicy.MajorVersions).

## AWS CLI
<a name="extended-support-viewing-support-dates-cli"></a>

To view the start and end dates for Aurora standard support and RDS Extended Support for your major engine versions by using the AWS CLI, run the [describe-db-major-engine-versions](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-major-engine-versions.html) command. 

This command returns the following relevant parameters:
+ `SupportedEngineLifecycles` – This parameter is an array of objects that include `LifecycleSupportName`, `LifecycleSupportStartDate`, and `LifecycleSupportEndDate`.
+ `LifecycleSupportName` – This parameter indicates the type of support the engine version is in: Aurora standard support (`open-source-rds-standard-support`) or RDS Extended Support (`open-source-rds-extended-support`). 
+ `LifecycleSupportStartDate` – This parameter lists the start date for either Aurora standard support or RDS Extended Support for the major engine version, depending on the value of `LifecycleSupportName`.
+ `LifecycleSupportEndDate` – This parameter lists the end date for either Aurora standard support or RDS Extended Support for the major engine version, depending on the value of `LifecycleSupportName`.

**Example**

The response example shows the start and end dates for the supported engine life cycles `open-source-rds-standard-support` and `open-source-rds-extended-support` for Aurora MySQL version 2 (MySQL 5.7). RDS Extended Support is available for Aurora MySQL version 2 (MySQL 5.7).

## RDS API
<a name="extended-support-viewing-support-dates-api"></a>

To view the start and end dates for Aurora standard support and RDS Extended Support for your major engine versions by using the RDS API, use the [DescribeDBMajorEngineVersions](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_DescribeDBMajorEngineVersions.html) operation. 

If RDS Extended Support is available for an engine version, then the response includes the parameter `SupportedEngineLifeCycles` as an array with two objects. One object includes the start and end dates for Aurora standard support. The second object includes the start and end dates for RDS Extended Support. 

If RDS Extended Support isn't available for an engine version, then the response only includes the parameter `SupportedEngineLifeCycles` as an array with a single object. This object includes the start and end dates for Aurora standard support.
