Date plus/minus another date results in what?

When you perform an operation involving the addition or subtraction of two dates, the result is typically expressed in terms of the difference between those two dates. This difference is calculated as the number of days that fall between them. Therefore, when you subtract one date from another in a system like NetSuite, the outcome is a count of days, which represents the exact span of time in between the two specified dates.

While calculations involving time can relate to hours, weeks, or months in various contexts, the basic arithmetic operation of subtracting one date from another delivers a straightforward numerical figure that corresponds to the total days elapsed between those dates, making it the most direct and universally understood result in date calculations within programming and data management systems.
