Airflow variables stores on the airflow database and it use the key, value structure to store and query variables. So if you want to set any variables on airflow do this on the UI: enter image description here

Also, it's recommended to use JSON value if you use start_date and end_date for example on a specific dag because of it reduce querying from 2 times to 1 time like this: enter image description here

Then you can use the variable like this:

variable = Variable.get("smaple")
start_date = variable['start_date']
end_date = variable['end_date']
