What is a recommended first step when dates are stored as strings before calculating differences?

Dates stored as strings can lead to incorrect calculations because strings don’t represent calendar time in a way that supports arithmetic. The best first step is to parse those strings and convert them into a proper date data type with a consistent format. Once you have dates as date objects, you can use built‑in date difference functions to compute differences accurately, correctly handling month lengths, leap years, and any time components. This conversion also resolves ambiguities from different formats (like dd/mm/yyyy versus mm/dd/yyyy) by applying a single, standard parsing rule. After conversion, you can then perform the actual difference calculation, and if you only need whole days, you can normalize or truncate time parts as needed.
