At a high level, you can use a microflow to calculate and return a list of dates between a start and end date. In the microflow, begin with the start date in UTC format and iterate through the dates using a while loop. Within the loop, increment a temporary current date variable by one day using the addDays function until the current date reaches the end date in UTC format. During each iteration, add the current date to a list of date objects (likely non-persistent), which will ultimately contain all the dates between the start and end dates. For more details on the addDays function, you can refer to the Mendix documentation: https://docs.mendix.com/refguide/add-date-function-calls/#addDays
