What formula would you use to set a custom field to automatically calculate the number of days since an employee was hired?

Using the formula that involves subtracting the hire date from the current date is the most logical and accurate approach to calculate the number of days since an employee was hired. This method works under the principle that by subtracting two dates, you can derive the time span between them.

In this specific case, when you subtract the hire date from the current date, the result is the number of days that have elapsed since the employee's hiring. This calculation provides a dynamic output that automatically updates each day as the current date moves forward, making it an effective way to track duration accurately without manual intervention.

Other methods, such as dividing the current date by the hire date or adding days to a new field, do not logically lead to a meaningful representation of time elapsed. Similarly, using a fixed value contradicts the need for an automatic calculation since it would not reflect the actual time since hiring, which could change daily. Thus, subtracting the hire date from the current date is the correct and effective formula for this scenario.
