I have a datepicker using NgbDate. I would like the format to spell out the month, hyphen, year. For example, August-2020. How can I format the following date this way?
effectiveDate = new NgbDate(date.year, date.month, date.day);
effectiveDate = effectiveDate.month.toString() + '-' +
effectiveDate.year.toString();
// the `effectiveDate` is of type `NgbDate`
effectiveDate = new NgbDate(date.year, date.month, date.day);
// you try to assign `string` to `NgbDate` which could work and it's very confusing
effectiveDate = effectiveDate.month.toString() + '-' +
effectiveDate.year.toString();
// instead it's better to create a variable for string value + string interpolation will make it easy to read
const formattedDate = `${effectiveDate.month}-${effectiveDate.year}`;
// or you can convert `NgbDate` into `Date` in the controller
this.jsDate = new Date(effectiveDate.year, effectiveDate.month - 1, effectiveDate.day);
// and use the `date` pipe in the component's HTML
jsDate | date: 'MM-yyyy'

How do I convert a date/time string to a DateTime object in Dart?
(8 answers)
Closed 1 year ago.
I am trying to parse String formatted like "23.1.2020" to DateTime object, but nothing works for me. I tried to use some packages like intl or date_format, but none of these can do the job.
DateTime todayDate = DateTime.parse("12.04.2020");
formatDate(todayDate, [yyyy, '/', mm, '/', dd, ' ', hh, ':', nn, ':', ss, ' ', am])
Do you have any idea, how to parse this?
Ok, I found way how to do that:
import 'package:intl/intl.dart';
DateFormat format = DateFormat("dd.MM.yyyy");
print(format.parse(date));
If you are absolutely sure that your date format will always be "dd.MM.yyyy" you could do this :
DateTime todayDate = DateTime.parse("12.04.2020".split('.').reversed.join());
This trick will format your date to "yyyyMMdd" format, which, according to the docs, is accepted by DateTime.parse().
Try out this package, Jiffy, it also runs on top of Intl, but makes it easier using momentjs syntax. See below
var date = Jiffy("12.04.2020", "dd.MM.yyyy").format("dd, Oct yy"); // 12, Apr 20
You can also do the following default formats
var date = Jiffy("12.04.2020", "dd.MM.yyyy").yMMMMd; // April 12, 2020
Hope this helps
Fuction Convert date to string :
String dateTostring(DateTime datevalue)
{
String _stringdate ="";
_stringdate = datevalue.month.toString()+"."+datevalue.day.toString()+"."+datevalue.year.toString() ;
return _stringdate;
}
Then fuction convert string to date:
DateTime dateStringtodate(String stringdate)
{
DateTime _stringdate;
List<String> validadeSplit = stringdate.split('.');
if(validadeSplit.length > 1)
{
int day = int.parse(validadeSplit[1].toString()));
int month = int.parse(validadeSplit[0].toString());
int year = int.parse(validadeSplit[2].toString());
_stringdate = DateTime.utc(year, day, month);
}
return _stringdate;
}
I work on flutter api wordpress project . How format date from wordpress api . date came in this format (2019-08-26T16:23:06) . i want to remove second and year . and month like (June , April)
you can use https://pub.dev/packages/intl and DateFormat :
DateTime dateTime = DateTime.parse(data[index]['date']);
String dateformat = DateFormat( "dd.MM.yyyy HH:mm").format(dateTime);
You can create a DateFormat object that fit your needs and use it to format your date.
Head over to the documentation to examples: https://api.flutter.dev/flutter/intl/DateFormat-class.html
I solve my problem with this function
timenow() {
var day = DateTime.parse(
snapshot.data[index].date)
.day;
var month = DateTime.parse(
snapshot.data[index].date)
.month;
var year = DateTime.parse(
snapshot.data[index].date)
.year;
var hour = DateTime.parse(
snapshot.data[index].date)
.hour;
var min = DateTime.parse(
snapshot.data[index].date)
.minute;
return year.toString() +
"/" +
month.toString() +
"/" +
day.toString() +
" " +
hour.toString() +
":" +
min.toString();
} // format date and time
In separate fields, I collect DisplayDate, DisplayTime, and TimeZone from the user. I want to put those into a moment and output the UTC formatted string to save into a hidden field that gets sent back to the server. I used the below code, but it uses the local timezone, rather than the selected TimeZone I entered. How do I get it to observe selTimeZonesVal?
var startTime = $('#StartTime');
var displayDateVal = $('#DisplayDate').val();
var displayTimeVal = $('#DisplayTime').val();
var selTimeZonesVal = $('#TimeZones').val();
var dtMoment = moment(displayDateVal + ' ' + displayTimeVal).tz(selTimeZonesVal);
var formattedUtc = dtMoment.utc().format('YYYY-MM-DDTHH:mm:ss');
startTime.val(formattedUtc);
The problem was with the date parsing. Somehow, moment was able to parse the date, but it would ignore the timezone if the date wasn't in ISO format.
The fix:
var startTime = $('#StartTimeUtc');
var displayDateVal = $('#DisplayDate').val();
var displayTimeVal = $('#DisplayTime').val();
var selTimeZonesVal = $('#TimeZones').val();
// Massage the date so moment can parse it (moment doesn't like mm/dd/yyyy)
var localDT = new Date(displayDateVal + ' ' + displayTimeVal);
var parseDT = moment(localDT).format('YYYY-MM-DDTHH:mm:ss')
var dtMoment = moment.tz(parseDT, selTimeZonesVal);
var formattedUtc = dtMoment.utc().format('YYYY-MM-DDTHH:mm:ss');
startTime.val(formattedUtc);
i want to get a datetime value from excel sheet and take the highest and the lowest date
i read the excel sheet and put it in datatable :
i tried this code :
protected void CheckTheFP(DataTable data)
{
if (data.Rows.Count != 0)
{
DateTime ds = new DateTime();
err.Text = DateTime.TryParseExact(data.Rows[0][2].ToString(), "MM/dd/yy hh:mm tt",
CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out ds) + "" ;
}
}
but i always get false ... don't know why ?
and is there a way to sort this datatable or take the highest and lowest date
this the excel sheet i read from
This format string should work: "M/dd/yy h:mm tt". I've used single M because the month has one digit, the same applies to the hours. I've used CultureInfo.InvariantCulture to prevent that all / will be replaced with your actual date-separator (in case that it's different).
You can use LINQ:
var allDateTimes = data.AsEnumerable()
.Select(row => DateTime.ParseExact(row.Field<string>("Time"), "M/dd/yy h:mm tt", CultureInfo.InvariantCulture));
DateTime min = allDateTimes.Min();
DateTime max = allDateTimes.Max();
If you want to be on the safe side you should use TryParseExact, for example with this code:
IEnumerable<DateTime> allDateTimes = data.AsEnumerable()
.Select(row => {
string time = row.Field<string>("Time").Trim();
DateTime dt;
if (DateTime.TryParseExact(time, "M/dd/yy h:mm tt", CultureInfo.InvariantCulture, DateTimeStyles.None, out dt))
return (DateTime?) dt;
return null; // set a breakpoint here to see which value could not be parsed
})
.Where(dt => dt.HasValue)
.Select(dt => dt.Value);
DateTime min = allDateTimes.Min();
DateTime max = allDateTimes.Max();
Edit: you: "when i try to use it on the date 11/2/14 4:42 PM you see the 11 is not in M datetime format
The month is not the problem. Use single d instead because the days can have a single digit also.
So: "M/d/yy h:mm tt"
Programming in Flex 4.5
I'm getting a date as a String.
I don't know what date or hour I'm getting.
I want to convert the string to date and take only the hours & minutes.
For example:
Getting - "2012-02-07T13:35:46+02:00"
I want to see: 13:35.
Suggestions or any other solutions?
After some digging, Solution:
var myDate:Date;
myDate = DateFormmater.parseDateString(myDateString);
var dateResult:String = myDate.getHours() + ":" + myDate.getMinutes();
Thanks anyway! :-)!
You can to use date.getHours() and date.getMinutes(). Try the following:
var d:Date = DateField.stringToDate("your_date_string","YYYY-MM-DD");
trace("hours: ", date.getHours()); // returns 13
trace("minutes: ", date.getMinutes()); // returns 35
private function init():void
{
var isoStr:String = "2012-02-07T13:35:46+02:00";
var d:Date = new Date;
d = isoToDate(isoStr)
trace(d.hours);
}
private function isoToDate(value:String):Date
{
var dateStr:String = value;
dateStr = dateStr.replace(/\-/g, "/");
dateStr = dateStr.replace("T", " ");
dateStr = dateStr.replace("+02:00", " GMT-0000");
return new Date(Date.parse(dateStr));
}
I see you've already got the answer, but for future users, here it is.
var myDateString:String="2012-02-07T13:35:46+02:00"
//This is of the format <yyyy-mm-dd>T<hh:mm:ss><UTC-OFFSET AS hh:mm>
//You could write your own function to parse it, or use Flex's DateFormatter class
var myDate:Date=DateFormatter.parseDateString(myDateString);
//Now, myDate has the date as a Flex Date type.
//You can use the various date functions. In this case,
trace(myDate.getHours()); //Traces the hh value
trace(myDate.getMinutes()); //Traces the mm value
