Date picker is not localized according to selected language in user preferences/workday waiver window

[timagixe]

Describe the issue
Date picker always displays months in English version.

To Reproduce
Steps to reproduce the behavior:

1. Go to User preferences
2. Change language to different from English
3. Open date picker of Overall balance start date
4. See that months of the date picker are not translated to the selected language

Expected behavior
I believe date picker should also be localized to selected language

Environment

I analysed this issue, findings below

1. In the current logic , we are using default date picker which isn't supporting any localizations (AFAIK) .
2. My proposal is to use jquery's datepicker from jquery-ui package, it's supporting localization
   Attached my codepen sample -

Let's discuss and move it further 👍

@RahulKannan12 that looks cool.
Can we also add theme support to it? Currently the datepicker is always white no matter the theme.

@araujoarthur0 Thanks.

Yes, I did some checks, it is possible to add, Can some one assign this to me, I can start working on it ?

[araujoarthur0]

@BikcromBiswas are you still working on this or is it ok to reassign?

@BikcromBiswas are you still working on this or is it ok to reassign?
Please reassign it

@araujoarthur0 I've raised the PR for fixing the date picker localizations, unfortunately I couldn't add the theme support to it, as it requires some more understanding for me, I'll do it as part of my upcoming PR's.

No need to change the date picker code. By changing the localization with the --lang parameter as mentioned here #10 (comment), also changes the naming of the months in the date picker.

[araujoarthur0]

That's rather interesting @soulflyman. Would you be willing to submit a PR for that?
I wonder how we would communicate to users the need to restart the app to see the changes in the datepickers. Maybe a popup when closing the preferences if the language was changed.

[soulflyman]

I think a popup when closing or changing the language would be the best way.

I'm not familiar with electron development to create a pull request. It was accidentally that I discovered this option and thought this might help.

I'm sorry that I can't help more.

@soulflyman no worries, thanks for the input!
