[RESOLVED] Help Novice with date conversion in Javascript

[VB.NETGAL]

Hi all, I'm a complete novice with Javascript so wondering if anybody can assist me with an issue I'm having.

On my webpage I have a minimum and maximum date set in hidden fields hdfMinDate and hdfMaxDate and are both string.

These values are passed into Javascript and it says min / max values on a date slider.

The min value is '2018.01.01'

The max value is '2018.09.01'

The code below correctly converts the min value to 1st Jan 2018 but the max value is getting converted to 31st Aug 2018

The actual values are in these url and what gets converted.

http://www.timestampgenerator.com/1535756400/

Is the function correct below? I don't know why my min date is converted to 1st Jan with 0 hours but the max date is converted to 31st Aug and 23 hours.

When i say I'm a novice the past couple of days are the first time I've had to look into it and have just about learnt how to step through it

    // Create object to store filter for each group
    var rangeFilters = {};
    var $grid;
    var MinDate = $("#hdfMinDate").val();
    var MaxDate = $("#hdfMaxDate").val();

    //Runs on load
    $(function () {
        $(".c-hosp-isotope__pak-sliders").hide();
        initalise();
    });

    //Intialise all items to
    function initalise() {
         rangeFilters = {
                'dateXYZ': {
                'min': new Date(MinDate).getTime() / 1000,
                'max': new Date(MaxDate).getTime() / 1000
            }
        };

Any ideas?

I bet if you look, it's returning 31 Aug 2018 23:59pm ... which is the end of the month. Typically when you want a date range, it's usually from the start of some month (Jan 1, 00:00 - midnight) through the end of the month (31 Aug 23:59pm) So that's what it's doing... it's adjusting the max date/time to be one minute prior to the date you selected. This way any date in the range will be >= the min date and < max date.

This way any date in the range will be >= the min date and < max date.

I did not know that. On a side note, is that why .NET's Random object works the same way, it provides a number >= the lower bounds and < the upper bounds?

Beats me... But likely since it can return a double. Never quite thought about it in that way before. Makes some sense.
