They are compared both by their date values and their calendars. {{jsxref("Temporal/PlainDate/since", "Temporal.PlainDate.prototype.since()")}} : Returns a new {{jsxref("Temporal.Duration")}} object representing the duration from another date (in a form convertible by {{jsxref("Temporal/PlainDate/from", "Temporal.PlainDate.from()")}}) to this date. The duration is positive if the other date is before this date, and negative if after. {{jsxref("Temporal/PlainDate/subtract", "Temporal.PlainDate.prototype.subtract()")}} : Returns a new Temporal.PlainDate object representing this date moved backward by a given duration (in a form convertible by {{jsxref("Temporal/Duration/from", "Temporal.Duration.from()")}}). {{jsxref("Temporal/PlainDate/toJSON", "Temporal.PlainDate.prototype.toJSON()")}} : Returns a string representing this date in the same RFC 9557 format as calling {{jsxref("Temporal/PlainDate/toString", "toString()")}}.
