4 years ago Maybe related to this is that in a 24-hour localized format hours would preferably be padded to 2 as well. So "0:00 AM" in 12-hour format makes sense, but "0:00" in 24-hour format not completely.

4 years ago These are valid requests. But some people may prefer only padding the month, or a 2-digit version of the year too. My point is: there are so many combinations that it seems easier to let each user define their preferred format.
For your specific use case:
function myFormat(d) { return d.toLocaleString({day:'2-digit', month:'2-digit', year:'numeric'}) }See MDN for a full description of formatting options.

4 years ago Would be really nice if there is a DateTime.DATE_LONG which is equal to { year: 'numeric', month: '2-digit', day: '2-digit' }

4 years ago I'm using Luxon as a Date Adapter for Angular Material Datepicker component. There I need to provide the different date formats that will be used by the datepicker ( https://github.com/angular/components/blob/80e4d3f1bebefd29f901f621dea928ccb38a35c8/src/components-examples/material/datepicker/datepicker-formats/datepicker-formats-example.ts#L18 ). I can only use formatting tokens there, that's why my request is for introducing a token, because I cannot format the dates via Javascript, using toLocaleString.

4 years ago @ccosmincc the code you are referencing is using moment, that's a different library.

4 years ago @GillesDebunne I know that the example is using moment, but that is not really relevant, I just put it there to provide more context on my use case: I have a configuration object where I can only format via tokens. Here is the same configuration, but for luxon, if it makes things more clear: https://gist.github.com/Zyzle/a9c5daa396882eb155282bcb454b9511#file-luxon-date-adapter-ts-L11

4 years ago This makes sense.
If you control that part, what prevents you from overloading the format
method, where the formatting seems to happen?
format(date: DateTime, displayFormat: any): string { if (displayFormat == MY_CUSTOM) return date..toLocaleString({ pick_your_choice: '2-digit' }) return date.toFormat(displayFormat); }

4 years ago @GillesDebunne I could introduce that logic in the format method, as you suggested, but I'm using Luxon in my entire project, not only for the datepicker, and I have one common place where I define the format, and at least 3 (most probably more in the future) other places where I handle Luxon dates based on that format (using date.toFormat), so I will be forced to introduce this custom logic everywhere.

4 years ago Using .Net Standard date and time format strings as a reference, check Short date pattern. The same token is used for dates, but is culture-specific whether it should use one or two digits:
2009-06-15T13:45:30 -> 6/15/2009 (en-US) 2009-06-15T13:45:30 -> 15/06/2009 (fr-FR) 2009-06-15T13:45:30 -> 2009/06/15 (ja-JP)
I checked the value ShortDatePattern for all the cultures, this is the result:

12 months ago Germany (de-DE) like most countries uses dd.MM.yyyy therefore a d.M.Y or dd.M.Y (or wtv) would is just wrong when using D in the Luxon formatter.
It does not only lead to confusion! For example, in a court case, the court could assume that all data from a system with such formatting issues is legally invalid as it is not compliant with the norm specifications of date and time formatting. Therefore it is strongly recommended to implement that either via DATE_LONG_FORMAT or qD or an additional func
The additional fix via raw settings is a bad idea, because for example Tabulator JS (a js data table tool like DataTables or GridJS) uses Luxon's outputformatter like that:
column.formatterParams = {
inputFormat:"yyyy-MM-ddTHH:ss",
outputFormat: "D z", //outputFormat:"dd/MM/yy HH:ss",
invalidPlaceholder:"(invalid date)",
timezone:"Europe/Berlin",
};Doing this manually would require me to detect the country and localize it manually, a stupid approach that easily doubles my work! Which substantiates the previous argumentation even further. Despite I have a TZ option, which does not really help^^
At best Luxon just auto detects the right Timezone from the User's browser and determines the right datetime format based on the TZ. Basically like it already does, just a little bit more advanced. Though I agree, that is also a implementation thing on the user's side. For example, the Tabulator's devs would be required to implement it. But if it's already in the library everyone profits from it and it's one-time work for everyone. Still, there is no reason why the formatting is wrong (means 03.8 != 3.8 != 03.08)

12 months ago @ksaadDE Your time zone and your locale are independent facts. Luxon uses both the system's default locale and its default time zone automatically, and gives you options to override both or either of those.
# running node with locale and TZ settings, same as the user's computer having a TZ set and a system locale set
❯ LANG=fr TZ=Australia/Sydney node
Welcome to Node.js v20.5.1.
Type ".help" for more information.
> { DateTime } = require("luxon")
// snip
> DateTime.now().toFormat("DDDD")
'lundi 13 novembre 2023'
> DateTime.now().toISO()
'2023-11-13T10:00:37.992+11:00' The whole point of "D" is that is, in fact, localized, using--by default--the user's locale. You can of course override this if for some reason you want to format something in a specific locale and make D mean the right thing there:
> DateTime.now().setLocale("de").toFormat("DDDD")
'Montag, 13. November 2023' If you want to externally specify a specific locale, you should do that independent of the zone (e.g. what happens when Germans travel?); in your case, that is presumably another parameter.

11 months ago @icambron Sorry if I did not point out (enough) the difference between locale and tz as well their independence. Though this was not my point.
My point was: a German wants to see the following format: 'dd.mm.YYYY HH:ii:ss' (01.02.2023 11:12:03). If a German travels they obviously wants to see this format everywhere. Although there are people, of course, wanting to see the current place's format. You are right this would be achieved by setLocale (although we were talking about D and not four-times D).
I agree to your point of view, that it is smarter to split language (locale or country wtv) and the timezone. Despite most systems automatically use the format of the region (Berlin) e.g. if you set the time to Europe/Berlin or some times Central European Time (CET) . That is why I used that argument.
Another aspect is the usage in web systems, where the user profile specifies the language (or tz) thus the format.
I looked it up in the docs of Tabulator.js and seemingly there's no option to set the locale for Luxon in that configuration: https://tabulator.info/docs/5.5/format#formatter-datetimediff and section above it - seemingly I have to ask there too.
Luxon uses both the system's default locale and its default time zone automatically, and gives you options to override both or either of those
Not in my test. For some reason it showed only the English format in a German Browser for CET / Berlin Time.
Opened issue in Tabulator for that: https://github.com/olifolkerd/tabulator/issues/4332

11 months ago If you do not set Settings.defaultLocale in Luxon then Luxon will not pass a locale key to any Intl.DateTimeFormat it creates. This will let the browser figure out the correct locale. If this does not have the desired effect for you, check if Intl.DateTimeFormat behaves the way you expect without a locale. If not, that would be either a browser misconfiguration or a browser bug.

Sometimes it works, sometimes not. But I have often discovered issues with Luxon in this regard. Though I also highly criticize the way it is implemented in Tabulator, where I need the correct settings/implementation. Sadly, I can't magically modify the foundations of the Luxon implementation, as they are hidden in Tabulator's code. :(
Currently there is the following formatting token: 'D' (localized numeric date) e.g.: 9/4/2017
Would it be possible to introduce a new token that will provide the same formatting, but padded to 2? e.g.: 09/04/2017
