Date calculations

To support calculations such as 'Date1 - Date2 = Number of days between dates', or 'Today() - Date1 = Number of days since Date1'.

Use case: In public solutions there is a certain guarantee that a citizen will be referred to treatment after a number of days has passed. These dates exist in data and you need to subtract them to calculate if the citizens rights have been kept. Private solutions: The difference between an invoice date and a shipping date would be the most common scenario.
