The Temporal.Now Object
The Temporal.Now object provides 5 methods to get the system's date and time.
One method for each date object
- Temporal.Now.instant()
- Temporal.Now.plainDateISO()
- Temporal.Now.plainTimeISO()
- Temporal.Now.plainDateTimeISO()
- Temporal.Now.zonedDateTimeISO()
And one method to get system's time zone:
- Temporal.Now.timeZoneId()
What is Temporal.Now?
Temporal.now is a Namespace object . Like the Math object, it is a container for methods.
These methods provide the current time in various formats (Instant, ZonedDateTime, PlainDateTime, etc) in nanoseconds precision .
Temporal.Now is static . It cannot be instantiated. You cannot use the new keyword to create a Temporal-Now. new Temporal.Now() will throw an error.
Instead, you call the methods directly on the namespace, such as Temporal.Now.instant().
Temporal.Now is serving as a replacement for the older Date.now() method.
Create a Temporal.Instant Object
The Temporal.Now.instant() method returns a Temporal.Instant object representing the current date and time.
An Instant represents an exact moment in time (UTC). It is similar to a timestamp.
Example
let now = Temporal.Now.instant();Create a Temporal.PlainDate Object
The Temporal.Now.plainDateISO() method is used to get the current date.
It returns a PlainDate object with the (year, month, day) in the ISO 8601 calendar, ignoring time zones and times.
A PlainDate object is ideal for calendar-based applications like birthdays, anniversaries, and scheduling, where the time of day does not matter.
Example
let today = Temporal.Now.plainDateISO();Create a Temporal.PlainTime Object
Use the plainTimeISO() method for time only .
It returns a PlainTime object with the current time in the ISO calendar.
Example
let today = Temporal.Now.plainTimeISO();Create a Temporal.PlainDateTime Object
Use the plainDateTimeISO() for date and time only .
It returns a PlainDateTime object in the ISO 8601 calendar, specifically ignoring time zones.
A PlainDateTime object is useful when the date and time for local scheduling, calendar elements, and date-time arithmetic where a time zone is not required.
Example
let dateTime = Temporal.Now.plainDateTimeISO();The JavaScript Date object has 1 method for getting the current time.
Temporal.Now has 5 methods for 5 different date objects.
Create a Temporal.ZonedDateTime Object
Use the zonedDateTimeISO() method when you need both date and time zone information.
It returns a Temporal.ZonedDateTime object that includes your system's time zone.
Example
let zoned = Temporal.Now.zonedDateTimeISO();Get the Current Time Zone
The timeZoneId() method returns a time zone identifier representing the system's current time zone.
Example
let text = Temporal.Now.timeZoneId();Revised March 2026
