Temporal #291
Description
This GitHub issue is for collecting web developer signals for Temporal.
The Temporal API allows you to work with dates, times, time zones, and durations. It is more powerful than the Date API.

What I want to do with this feature
I want to handle partial date and time data (only time or only day, or dates without timezone).
What I'm having to do in the meantime
In the meantime I use JavaScript Date objects to represent such data, but I have to be careful to set the value of unused fields for comparisons to work as expected (forgetting to do so can lead to unexpected problems).

What I'm having to do in the meantime
im using a polyfill and some overflow code to achive what i want.

What I want to do with this feature
Easily handle dates, times, months (with years but not dates) in a straightforward manner, without writing string parsers and normaliser functions. The localisation support and timezone handling is an added bonus.
What I'm having to do in the meantime
I have to use a polyfill if there's any chance my users use iOS or Safari.

What I want to do with this feature
Let's see I am using temporal for zdt (ZonedDateTime) and IANA time zone names and time zone support in ways that Date() never could
I'm using temporal inside an astronomical/celestial app with topographic observer corrections, so strong local time zone support is very much a hard requirement.
What I'm having to do in the meantime
BTW, this just doesn't work on iOS right now, and I have no intention of backfilling or polyfilling or anything else.

@anthonymhumphreys I took the liberty to apply the template to your comment. I did not change the content of your comment, I only added the headings from the template. Thank you for your comment.

What I want to do with this feature
I work on an app used by folks across the country with a lot of client-set dates and datetimes. These date(time)s have no need to be timezone-aware, so using Temporal (without introducing a polyfill) will allow us to simplify all of our date handling and remove dependencies.
Workarounds currently used
Use
date-fns/date-fns-tzfor date manipulation and timezone handling (despite formatting all going throughIntl.DateTimeFormat). We also have our own robust suite of helpers to ensure timezones are displayed consistently regardless of server/client drift.Submitted via Developer Signals

What I want to do with this feature
I want to use a better API than the Date API, without resorting to 3rd party libraries
Workarounds currently used
We currently use the legacy Moment.js library, which is 150 KB in size and no longer maintained.

I want to use
Temporal.Durationto display the time passed on a video in MM:SS format.What I'm having to do in the meantime
I use
Math.floor()and/to convert thecurrentTimeto a human-readable format.anthonymhumphreys commentedon Sep 21, 2026
What I want to do with this feature
const tmpdzt = Object.freeze(dzt);
What I'm having to do in the meantime
const tmpEpochMilliSecs = dzt.epochMilliseconds
Cipscis commentedon Sep 30, 2026
What I want to do with this feature
I want to represent dates without time or time zone information attached.
What I'm having to do in the meantime
I'm using a mix of custom
{ year: number; month: number; day: number; }objects andYYYY-mm-ddstrings, and need some custom functions for checking if a date in this representation aligns with the current day based on the user's time zone.
