How Jira is calculates the start to the sprint and closed items before sprint start?

[dimitaryonchev]

Hi, I have the following case:

- I have a story assigned within sprint 10.

- The old sprint 9 is closed on 01/01/2020 09:00;

- The new sprint 10 starts on 01/01/2020 at 18:00;

- The story becomes closed on 01/01/2020 at 14:00 (before actual sprint start).

We have a time hole between the new and the old sprints. So, my question is, is this story would become part of the sprint 10, including burndown chart, or it will be ignored? I.e. how Jira calculates this case - by Date or by DateTime?
