Listing of start and end dates of sprints

[Tatsuya Tenjin]

I want to do Listing of start and end dates of sprints.

On rare occasions, we may extend the duration of a sprint, and we want to store and manage such information in a spreadsheet or other format.
Is there a good way to do this?

Hi @Tatsuya Tenjin welcome to the Atlassian community.

I'm not sure if you have already explored this option. If not, please see the below screen shots and the steps.

In your Scrum board, click on backlog and on the landing page, navigate to the backlogs section. Their you will find an option to "Create Sprint".

Please click on that button to get a new Sprint number followed by their dates (US Sprint 26 screenshot). You may click on "Create Sprint" multiple times to create the blank Sprint boards with their dates. This will allow to change the Sprint duration (before start of the Sprint) as well get a visibility to all Jira stakeholders besides moving the backlogs to their desired Sprint number as part of your release planning.
