The Temporal.Now namespace object contains static methods for getting the current time in various formats.

The era accessor property of Temporal.ZonedDateTime instances returns a calendar-specific lowercase string representing the era of this date, or undefined if the calendar does not use eras (e.g., ISO 8601). era and eraYear together uniquely identify a year in a calendar, in the same way that year does. It is calendar-dependent.

The monthsInYear accessor property of Temporal.PlainYearMonth instances returns a positive integer representing the number of months in the year of this date. It is calendar-dependent.

The dayOfWeek accessor property of Temporal.PlainDateTime instances returns a positive integer representing the 1-based day index in the week of this date. Days in a week are numbered sequentially from 1 to daysInWeek, with each number mapping to its name. It is calendar-dependent.

The subtract() method of Temporal.PlainTime instances returns a new Temporal.PlainTime object representing this time moved backward by a given duration (in a form convertible by Temporal.Duration.from()), wrapping around the clock if necessary.

The toJSON() method of Temporal.PlainDateTime instances returns a string representing this date-time in the same RFC 9557 format as calling toString(). It is intended to be implicitly called by JSON.stringify().

The equals() method of Temporal.PlainDateTime instances returns true if this date-time is equivalent in value to another date-time (in a form convertible by Temporal.PlainDateTime.from()), and false otherwise. They are compared both by their date and time values and their calendars, so two date-times from different calendars may be considered equal by Temporal.PlainDateTime.compare() but not by equals().

The valueOf() method of Temporal.ZonedDateTime instances throws a TypeError, which prevents Temporal.ZonedDateTime instances from being implicitly converted to primitives when used in arithmetic or comparison operations.

The inLeapYear accessor property of Temporal.PlainDate instances returns a boolean indicating whether this date is in a leap year. A leap year is a year that has more days (due to a leap day or leap month) than a common year. It is calendar-dependent.

The toJSON() method of Temporal.Instant instances returns a string representing this instant in the same RFC 9557 format as calling toString(). It is intended to be implicitly called by JSON.stringify().
