It must have the same calendar as this. options {{optional_inline}} : An object containing the options for {{jsxref("Temporal/Duration/round", "Temporal.Duration.prototype.round()")}}, which includes largestUnit, roundingIncrement, roundingMode, and smallestUnit. largestUnit and smallestUnit accept all possible units. For largestUnit, the default value "auto" means "days" or smallestUnit, whichever is greater. For smallestUnit, the default value is "nanoseconds". The current date is used as the relativeTo option. Note that using units larger than "days" may make the duration not portable to other cal Attribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
