I have this
DateFormat dateFormat = new SimpleDateFormat("MM");
Date date = new Date();
I know the value as 10 but have got no idea how to print it out. How do I convert it to an int? If there even is a way?
date.getMonth()
it is deprecated - you should be using Calendar, but if you don't want to change, that'll do it. It is 0 indexed, so remember to change the resulting value appropriately.

I am getting date and time from store. In data base its look like this
Need to know how can I show this as DD/MM/YY
I am trying to do like this
String timeString = snapshot.data[index]['lastupdate'].toString();
DateTime date = DateTime.parse(timeString);
print(DateFormat('yyyy-MM-dd').format(date));
Its showing error of Invalid date format
Try like this your lastupdate date is not convertime inDate thats why its showing error
DateTime date = DateTime.parse(snapshot.data[index]['lastupdate'].toDate().toString());
print(DateFormat('dd-MMM-yyy').format(date));
Use function to get date from Timestamp like this:
readDate(Timestamp dateTime) {
DateTime date = DateTime.parse(dateTime.toDate().toString());
// add DateFormat What you want. Look at the below comment example
//String formatedDate = DateFormat('dd-MMM-yyy').format(date);
String formatedDate = DateFormat.yMMMMd().format(date);
return formatedDate;
}
Use the function when you want it.
For example:
Text(readDOB(streamSnapshot.data!["dob"]))
For this you should install intl package. read
I am struggling to find a way to parse 2 YYYY-MM-DD dates in dart/Flutter. I need to find out whether a given date is before another date in terms of number of days in utc. If they are the same or it is in the future it should return false.
Thanks,
with intl package (https://pub.dev/packages/intl) you can convert those strings to actual date objects and then compare them easily
just compare them with
DateTime date1 = DateTime.now();
DateTime date2 = DateTime.now();
if(date1.millisecondsSinceEpoch > date2.millisecondsSinceEpoch){
return false;
}
return true;
Try out this package, Jiffy
First, parse the string into a Jiffy instance
Jiffy jiffy1 = Jiffy("2019-12-01")..utc();
Jiffy jiffy2 = Jiffy("2019-12-20")..utc();
Next is to check if it is the same or in the future in terms of days
jiffy1.isSameOrBefore(jiffy2, Units.DAY); // true
You can also check if it is the same or in the past in terms of days
jiffy1.isSameOrAfter(jiffy2, Units.DAY); // false
Check out this documentation for more
Hope this helped
I am trying to add a day to my date:
let createdDate = moment(new Date()).utc().format();
let expirationDate = moment(createdDate).add(1, 'd');
console.log(expirationDate);
However, this keeps returning an obscure object {_i: "2017-12-20T21:06:21+00:00", _f: "YYYY-MM-DDTHH:mm:ss Z", _l: undefined, _isUTC: false, _a: Array(7), …}

Does anyone know what I might be doing wrong?
You are logging a moment object. As the Internal Properties guide states:
To print out the value of a Moment, use .format(), .toString() or .toISOString().
let createdDate = moment(new Date()).utc().format();
let expirationDate = moment(createdDate).add(1, 'd');
console.log(expirationDate.format());
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.min.js"></script>
Please note that you can get the current date using moment() (no need to use new Date()) or moment.utc().
I will go with this one, simple works for me and I don't think you need other function to only add day in moment.
var yourPreviousDate = new Date();
var yourExpectedDate = moment(yourPreviousDate).add(1, 'd')._d;
The add method modifies the moment object. So when you log it, you're not getting an obscure object, you're getting the moment object you're working with. Are you expecting a formatted date? Then use format or some other method.
I agree with other answers just providing shortcut and different ways
You can do the format at the same time
moment().add(1,'d').format('YYYY-MM-DD');
or you can just format any date or date object
moment(result.StartDate).format('YYYY-MM-DD');
I have been struggling with this even after doing so much of research on such a simple thing, so I need some help here.
I need to pass current date in date data type only in 'yyyy-MM-dd' format. SimpleDateFormat converts current date to string type and while trying to parse though it gets converted to Date type but changes the format.
I need currentDate in the format 'yyyy-MM-dd' of Date Type.
if(!session.dtfromDate && !session.dttoDate)
eq("startDate", currentDate)
I have managed to figure out a solutions to this. First got my desired format which obviously converted it to a String and then parsed this to a Date. It has worked perfectly fine.
SimpleDateFormat nsdf = new SimpleDateFormat('yyyy-MM-dd')
String currentDate = new SimpleDateFormat('yyyy-MM-dd').format(new Date());
Date newDate = (Date)nsdf.parse(currentDate)
if(!session.dtfromDate && !session.dttoDate)
eq("startDate", newDate)
I need t use the CQ5 xtype 'datefield' since I need only the date and not time tombe entered by the author.
But the issue is that 'datefield' saves the date in JCR as a String and not as a timestap [ as it does when 'datetime' is used.]
Is there a work around to save the date as a timestamp ?
I don't think it is possible to save the date as timestamp using datefield, without meddling with the default script. But as a workaround, you can use datetime and set the property hideTime to true, to hide the time part, so that the author will not be able to author it.
The json for the config is shown below.
{ "fieldLabel":"Date",
"xtype":"datetime",
"hideTime":true,
"name":"./date",
"defaultValue":"now",
"jcr:primaryType":"cq:Widget"
}
You can add defaultValue to 'now', if you want current date to be initialized as the default, if not explicitly filled in by the author, else it can be ignored.
NOTE: The defaultValue: 'now' doesnt work for me in IE (i am using IE 11 and emulating the previous versions through dev tools), but it works fine in Chrome and Mozilla.
A rough workaround for your jsp:
<%#page import="java.text.SimpleDateFormat,java.util.Date"%>
<%
SimpleDateFormat displayDateFormat = new SimpleDateFormat("dd MMM yyyy");
String dateField = properties.get("nameofdatefield", "");
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yy");
Date formattedDate = sdf.parse(dateField);
String formattedDateStr = displayDateFormat.format(formattedDate);
out.println('Example of formated string'+formattedDateStr);
%>
From the above, you can also convert it to a Date Object, depending on what you wish to manipulate.
Let me know if the above example helps
