Hi all,

where could i find a good documentations about “moment” or “date” ??!  
It’s really complex to understand how works this class…

Today is month October( month n° 10) and when i write  
“moment().month()” return 9.  
“moment().months()” return 9;  
“moment().utc).month()” return 9;  
“moment().local().month()” return 9;

but if i write in console “moment” it has the value 10 .

anyone know?!

new Date().getMonth() // 9 (index-0)  
moment().format(‘M’) // 10 (month as digit)

if you are in a position to choose the library, i would recommend against a mutable API like moment.

I recommend [luxon](https://moment.github.io/luxon/):

## Features

- [DateTime](https://moment.github.io/luxon/docs/class/src/datetime.js~DateTime.html), [Duration](https://moment.github.io/luxon/docs/class/src/duration.js~Duration.html), and [Interval](https://moment.github.io/luxon/docs/class/src/interval.js~Interval.html) types.
- Immutable, chainable, unambiguous API.
- Parsing and formatting for common and custom formats.
- Native time zone and Intl support (no locale or tz files).

Do you suggest anyway to use luxon ?  
I think that moment functions can be comprehensive… or no?

Luxon is much smaller and simpler because it relies on newer browser API’s for i18n and timezones. Check out the [support matrix](https://moment.github.io/luxon/docs/manual/matrix.html).

If you need to support i18n and timezones in older browsers you’ll need to use moment + plugins and the whole lot can be quite large.

After hours spent on “try” to understand how to work with moment / date of typescript i try this Luxon. It seems workable but how can i get a Luxon DateTime from European Timezone date?

Try e.g. DateTime.local().setZone(‘Europe/Paris’);

</div>

UTCDate.toLocal().plus({ minutes: UTCDate.offset }).toFormat(“dd/MM/yyyy HH:mm”));

this is the answer! but it can be possible to write this entire line to have the local time from utc…

</div>

if you have a utc date you can just add Z to the end and it will convert local for you

let localTime = new Date(utcDate + “Z”);
