I wanted to create a pull request, but github said the following: "Choose different branches or forks above to discuss and review changes."

Anyway, here is dutch translatation:

  nl: {
    weekShortAbbreviation: ["m", "d", "w", "d", "v", "z", "z"],
    weekAbbreviation: ["ma", "di", "wo", "do", "vr", "za", "zo"],
    weekFullName: ["maandag", "dinsdag", "woensdag", "Thursday", "Friday", "Saturday", "Sunday"],
    monthAbbreviation: ["Jan", "Feb", "Mar", "Apr", "May", "June", "July", "Aug", "Sept", "Oct", "Nov", "Dec"],
    monthFullName: [
      "januari",
      "februari",
      "maart",
      "april",
      "mei",
      "juni",
      "juli",
      "augustus",
      "september",
      "oktober",
      "november",
      "december",
    ],
    today: "Vandaag",
    doneName: "Klaar",
    prevName: "Vorige",
    nextName:"Volgende"
  },

Days and months are lowercase on prupose. This is the correct way in dutch.

I would really apreciate if you could add this. I want to use it in my project real bad :)

I have applied a dashed outline to show which dates actually have that calendar-weekend class.

27 and 28 of the prev month should not have that class.
The 5th of November should have the class.

Id like to include the spanish support for the timepicker

Is there a way to style dates that have been previously selected? For example, as a user selects dates, possibly store those in an array and then add some type of styling to the calendar (change of color, dot on the date, etc.) that indicates the user has already interacted with that date?

This looks great plan to use it in my next project.
It would be nice to also include time / timezone as an option.

When jumping to switch the date (not clicking the prev or next button), the disabled date in the view will not be refreshed.

This commit seems to have broken the calendar: 81f1191

Before

After (two times the 31.)

@TIOvOIT mentioning you here since I think it's important

When I wrote the REPL Demo on the svelte.dev site, I found that there may be performance issues.

See REPL

<script>
  import { beforeUpdate } from "svelte";
  import Datepicker from "praecox-datepicker";

  let ty = new Date().getFullYear();
  let tm = new Date().getMonth() + 1;
  let disabled = [];
  beforeUpdate(() => {
    disabled = [
      ['2021-10-13'] // must be disabled but not
    ];
  });
</script>

<Datepicker {disabled} nowDate={'2021-10-1'} />

Need to add two-way props binding support.

perhaps after both dates are selected a new click should erase both and interpret new click as start date?

From your demo

Hi, it seems that the marked prop is not working as intended for dates higher than 9.

Here's a REPL: https://svelte.dev/repl/9245ac9b9f8246b497d8e892581eae39?version=3.29.0

2021-10-9 -> Works
2021-10-10 -> Does not work

Also, afaik a leading zero is the standard for dates in the format "yyyy-mm-dd". Adding a leading zero breaks it too.

Here is how to reproduce the issues:

1. Open https://svelte.dev/repl/f153bee994974251b59041832a099427?version=3.29.0
2. Select Nov 2001, you will find it shows 26 on Nov 25
3. Go to the next month, you will find there is no Dec 31
4. Go to the next month, you will find it shows 30 on December 31

Can't provide a code example right now but just want to check this is supported?
