### What do you see as an issue? The issue is that users are unaware of scheduling behaviour between transition of when [daylight saving time](https://en.wikipedia.org/wiki/Daylight_saving_time) is observed and when it is not. For daylight time saving observing timezones, at the cusp of when switching between when daylight saving time is **NOT** observed to when it is, there is an hour that does not exist. For example, 2 AM Central Time ("America/Chicago") does not exist on March 10th 2024. * `2024-03-10 7:59 UTC is 1:59 AM CT (CST)` * `2024-03-10 8:00 UTC is 3:00 AM CT (CDT)` * `2024-03-10 8:01 UTC is 3:01 AM CT (CDT)` For daylight time saving observing timezones, at the cusp of when switching between when daylight saving time is observed to when it is **NOT**, there is an hour that is repeated. For example, 1 AM Central Time ("America/Chicago") happens twice on November 3rd 2024. * `2024-11-03 6:59 UTC is 1:59 AM CT (CDT)` * `2024-11-03 7:00 UTC is 1:00 AM CT (CDT)` * `2024-11-03 7:01 UTC is 1:01 AM CT (CST)` * `2024-11-03 7:59 UTC is 1:59 AM CT (CST)` * `2024-11-03 8:00 UTC is 2:00 AM CT (CST)` * `2024-11-03 8:01 UTC is 2:01 AM CT (CST)` ### Solving the problem A description of the effects of these impacted schedule intervals in terms of dagrun creation as that is what drives task scheduling. Without a dagrun, there are no tasks. ### Anything else _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
