Set date month by new Date() object is not equal to the month displayed in the datepicker

I am setting selected date into datepicker by:

public selectedDate: Date = new Date(2014,2,23);

and then using this variable in html datepicker

<DatePickerField [(ngModel)]="selectedDate" locale="pl_PL" class="input">

The result date is not 2014.02.23 but 2014.03.23 -> the datepicker set allways one moth plus.

I am using nativescript angular template and I have installed the 1.2.1 version of datepicker plugin

Hi @letsgoforaride
This is expected - in JavaScript dates have their months represented by a value from 0 to 11 as demonstrated here. You can just console.log(selectedDate); and verify that this code new Date(2014,2,23) creates the date 23rd of March, 2014.

Please note that when you create a date in xml/html, another Date constructor is used, where months are represented as you would expect (between 1 and 12). For example console.log(new Date("2019/02/24")); would print 24th of February, 2019.
