With apex, I pass a string like:
2017-02-05T01:44:00.000Z
to an apex function from javascript, however, when attempting to turn it into a datetime, it gives me invalid date/time error. I can create a date with it like
date newdate = date.valueOf(dateString);
but if I do datetime newdate = datetime.valueOf(dateString) I get the error. I don't get why it sees the string as incorrectly formatted to give invalid date/time. When I create just a date instead of datetime, I lose the time and it sets it to 00:00:00.
Thank you to anyone with some insight on how to create the datetime in apex! I have been trying to find the apex format and from what I see. I can't understand why it thinks this is invalid.
Try this.
String inpputString = '2017-02-05T01:44:00.000Z';
DateTime resultDateTime = DateTime.ValueofGmt(inpputString.replace('T', ' '));
System.Debug('resultDateTime>> '+resultDateTime);
Output:
10:10:41:011 USER_DEBUG [4]|DEBUG|resultDateTime>> 2017-02-05 01:44:00

I have a date which is a string and looks like this:
String day = "30-11-2022 12:27";
I am trying to convert the above string to DateTime object and convert the 24hr time to 12hr. I am using the following code:
DateFormat("dd-MM-yyyy hh:mm a").parse(day);
It was working before but today the parsing is causing format exception error. The error message is shown below:
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FormatException: Trying to read from 30-11-2022 12:27 at position 17
Why am I getting error while parsing now? How to fix it?
There must be a simpler solution, but it works this way:
final str = "30-11-2022 12:27";
final date = DateFormat("dd-MM-yyyy hh:mm").parse(str);
final formated = DateFormat("dd-MM-yyyy h:mm a").format(date);
The format for a 24-hr time is 'HH:mm'. The key is to call add_jm(). Just do this:
final day = '30-11-2022 12:27';
final dateTime = DateFormat('dd-MM-yyyy HH:mm').parse(day);
final formatted = DateFormat('dd-MM-yyy').add_jm().format(dateTime);
print(formatted);
The output is:
30-11-2022 12:27 PM
can try this. hope your problem solved
DateTime dateTime = DateFormat('yyyy/MM/dd h:m').parse(date);
final DateFormat formatter = DateFormat('yyyy-MM-dd h:m a');
final String formatted = formatter.format(dateTime);
It really doesn't matter for datetime that the input date is in am format or not, because you can parse it to what ever format you want. For both option when you parse your string, it will save it in regular form. So just try this:
String day = "30-11-2022 12:27";
DateTime date = normalFormat.parse(day);
and when ever you want show it as AM, just format date;

You specified a DateFormat format string that uses a, which indicates that you want to parse an AM/PM marker, but the string you try to parse is "30-11-2022 12:27", which lacks it.
If you're trying to convert a 24-hour time to a 12-hour time, those are fundamentally two different formats, so you will two different DateFormat objects. Note that the format pattern for hours is different for 12-hour times (h) than for 24-hour ones (H):
String day = "30-11-2022 12:27";
var datetime = DateFormat("dd-MM-yyyy HH:mm").parse(day);
// Prints: 30-11-2022 12:27 PM
print(DateFormat('dd-MM-yyyy hh:mm a').format(datetime));
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
So far I try new DateFormat("MM/dd/yy").parse('04/03/20') but it produce 04/03/0020 date.
You have to formate this date using formate method of datetime class. However, you need to convert string to datetime using parse method because datetime formate take datatime as an argument.
Following line help you to achieve desire output:
print(DateFormat("MM/dd/yy")
.format(DateFormat("MM/dd/yy").parse('04/03/20')));
UPDATE:
This following code will give result as you expected but it is hard to find out it is 1920 or 2020?
DateTime _dateTime = DateFormat("mm/dd/yy").parse('04/03/20');
_dateTime = DateTime(2000 + _dateTime.year, _dateTime.month, _dateTime.day);
print(_dateTime);
I have a component that uses a datepicker. The datepicker needs a dateFormat property that fits the momentjs pattern, for example 'DD.MM.YYYY' or 'MM/DD/YYYY'.
The date formatting is handled by react-intl. This works fine when converting from a date to a string (via formatDate). However, I need to retrieve the pattern as described above.
My goal is to do something like
dateFormat = this.props.intl.extractDateFormat() // returns 'DD.MM.YYYY'
I have found this similar question, but the only answer relies on parsing the string, which I cannot do, because I do not know whether Day or Month will come first in the formatted date.
If it is possible to convert this string to a date and somehow retrieve the format from momentjs, that would also be a good solution.
I was able to get the date format from react-intl. To do this, I defined an example date and had it formatted by react-intl, and then parsed the format by referring to the original string.
My component which is exported as injectIntl(Component) has this method:
deriveDateFormat = () => {
const isoString = '2018-09-25' // example date!
const intlString = this.formatDate(isoString) // generate a formatted date
const dateParts = isoString.split('-') // prepare to replace with pattern parts
return intlString
.replace(dateParts[2], 'DD')
.replace(dateParts[1], 'MM')
.replace(dateParts[0], 'YYYY')
}
The date will e.g. be formatted to '09/25/2018', and this function would return 'MM/DD/YYYY', a format which can be used by Moment.js.
This function only works if you know that the month and day will always be displayed with two digits. It would fail if the format is something like 9/25/2018.
I have not found a way to extract the date format from react-intl directly.
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)
