Date Validation

All good folks! My problem is the following, I looked for everything here and I didn't find something similar. I need to create a custom column that returns me a result if the current date is within the date range and another result if it isn't. For example:

Today=12/21/2012

Start date   End date   Result

12/20/2021   12/24/2021   1

12/17/2021   12/20/2021   0

12/21/2021   12/22/2021   1

12/23/2021   12/24/2021   1

Note: If the date range is in the future, that is, it is greater than the current day for example, the result must also be 1, as the date range is still valid.

Well I hope I managed to explain. Thanks.
