Working with date formats in Java and MySQL

Ok this is really bugging me.
I am developing a web app and I need to work with dates. When a date is displayed in a view, or whenever a date is entered into a form I need the format to be dd/mm/yyyy.
What data type do I choose for my SQL database columns which contain dates. 'Date' doesn't seem to work, do I use varchar?
But If I use varchar how do I use java script to perform arithmetic with dates.
Do I do some conversions server-side?
Please advise the best practices.
Also Im using laravel if theres any useful stuff already built in.

Date is the correct type to use in SQL DB.
To access the value use ISO date format "YYYY-MM-DD HH:mm:ss" .
You can create it from Java Date Object by using toISOString() method.
For easier time format conversion I can also recommend to check out Moment.js.

Best practice to save the date in MySQL table as date field only. Which saves the date string in YYYY-MM-DD HH:mm:ss format.
You need to make sure the following things.
Before inserting date into MySQL change the format of date string to YYYY-MM-DD HH:mm:ss.
When you retrieve the date from database convert the date string from YYYY-MM-DD HH:mm:ss to your desired format.
You can use SimpleDateFormat class in Java to convert the dates
format. Use format() function to format the date in desired and
parse() function to get the Java date object from string.
Reference: https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

You should use varchar2 in mysql.
You can retrieve that varchar type date in javascript and create date object.
var d=dbdate;
var date = new Date(d);
And you can perform all javascript functions on date.
Hope it will help.

Javascript Date() object supports separate entries of date by:
var date=new Date();
var y=date.getFullYear();//4 digits
var m=date.getMonth()+1;//0-11 digits, plus 1 for true state
var d=date.getDate();//1-31
var dateSQL=y+'-'+m+'-'+d;//i.e 2016-07-25

you can use MySQL filed as datetime and also insert datetime format but when you will show then process it as you want as like
when you insert value in table then you can also format it as like
<?php $mysqltime = date ("Y-m-d H:i:s", $phptime); ?>
where $phptime is your input variable
$str = suppose $row['date'] (mysql filed value)
date("d/m/Y", strtotime($str));
where $str your retrieve date filed

DateRangePicker bootstrap plugin display one format send another

I have a dashboard that is requesting data from a servlet, the servlet is pulling data from a DB and needs the time formatted for a timestamp :YYYY-MM-DDThh:mm:ss+00:00. I have a parser on the servlet set up to parse this string to an sql timestamp.
I'm using the daterangpicker Bootstrap plugin. I would like to display the date format on the dashboard like so: DD/MM/YYYY hh:mm - DD/MM/YYYY hh:mm
I'm currently formatting the date like so: YYYY-MM-DDThh:mm:ss - YYYY-MM-DDThh:mm:ss
Then in my JavaScript I'm slicing it to the format I need to send:
var startDate = $('#range').val().slice(0, 19) + '+00:00';
var endDate = $('#range').val().slice(22, 41) + '+00:00';
I could obviously do a lot more slicing to achieve this, but maybe there's an easier solution?
I've tried two solutions I found on stack but both methods failed to pull the dateRange as a dateRange object: this and this

Convert date string to date object using moment

there is a situation which I need to convert a date string which consist a timezone abbrevation to a Moment object and parse it. How can I do this? sample date is like below:
var dateString = "2015-01-14 06:57:47 ECT";
be aware that I need the timezone of this date, because Im going to do another conversion to another zone, so if we just consider the date we miss the accuracy.

I don't think moment can handle a timezone name, you should replace ECT with the offset value, like +0200

Compare ISO date without time stamp in javascript

I am querying data using OData, url looks like http://myurl.com/api/Customer?$filter=ResDate eq DateTime'2014-03-15T12:01:55.123'.
I'm getting date/time from jquery.datepicker instead of the static date and using moment.js to convert from DD-MM-YYYY to YYYY-MM-DDTHH:mm:ss in order to pass it to web service.
function convertDateToISOdate(date){
var newDate = moment(date,'DD-MM-YYYY').format('YYYY-MM-DDTHH:mm:ss');
return newDate;
}
Date returns from the function, is 2014-03-15T00:00:00.
Problem : 2014-03-15T12:01:55.123 is not equal to 2014-03-15T00:00:00, so there's no record selected.
What I want is , just to compare the date , not include time stamp.
Note : I can not change the format date/time at server side(Web service) because it's not belongs to me.
Any idea is much appreciated.

Your first call to moment(date,'DD-M-YYYY') is stripping the time information from the incoming data. try using moment(date) (no format) instead because momentjs recognizes your incoming date format intrinsically, without having to be told which format to use, and will correctly parse the H:M:S data, too.
MomentJS date parse information

angular.ui DatePicker how to set the Date format?

I am using the angular.ui DatePicker
http://angular-ui.github.io/bootstrap/#/datepicker
In the doc it says:
"Everything is formatted using the date filter and thus is also localized."
I am having a hard time figuring out how to use the date filter to control the date format set in the model.
Using the DatePicker I am getting a date format set in the model like this:
"2013-09-07T03:18:43.000Z"
However, I am trying to serialize with Grails, and I want my date format to be like this:
"2013-09-07T03:18:43Z"
How do I configure the DatePicker to output this format of date? Or since it is a JavaScript date, do I have to do this at the server side? Ultimately, I would like to send:
"2013-09-07T03:18:43Z"
in a JSON put to the server.
TIA

You can follow this trademark way of parsing the default ISO date format to your own format stripping out the milliseconds, in client side.
Or, in the server side (Grails) you can parse the string to your own format as below:
Date.parse("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "2013-09-07T03:18:43.000Z")
.format("yyyy-MM-dd'T'HH:mm:ss'Z'")
//prints "2013-09-07T03:18:43Z"
If you are persisting a Date instead of a String, just use Date.parse(..) (without .format).
