I want to convert a string to date before storing it and I used
SimpleDateFormat format = new SimpleDateFormat("yyyy-mm-dd");
Date returnDate = format.parse(date);
When I ran this with sample date:
the input string for date conversion is 2014-05-06
the parsed date is Mon Jan 06 00:05:00 IST 2014
now when I store the returnDate in MySql the value is 2014-01-06 00:05:00
Why is the date changed ? Want to know if I am missing something. I went through the posts related to date string conversion : How to convert a date from a Datepicker to Mysql DATETIME format using java?
In your DateFormat use MM for month instead of mm, that is for minutes
Reference: http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html
You can use like this :
Date mDate= new Date(System.currentTimeMillis());
SimpleDateFormat mDateFormat= new SimpleDateFormat("dd MMM yyyy HH:mm a");
String dateformat=mDateFormat.format(mDate);
the string ["dd MMM yyyy HH:mm a"] can be changed according to need of formate.
Like in your case : "yyyy-mm-dd

I have a database file with mm/dd/yy values for events, and I want to display the date as something similar to "Day(word), day(number), month(word)".
01/07/19 into
Monday 4th Jan or Monday 4 Jan or something similar.
Try something like this:
LocalDate.of(2019, 3, 2).format(DateTimeFormatter.ofPattern("EEE dd MMM YYYY"))
You can use SimpleDateFormat to convert the string to date and then convert back to String like this :
DateFormat format1 = new SimpleDateFormat("MM-dd-yyyy");
Date date = format1.parse("01-01-2019");
DateFormat format2 = new SimpleDateFormat("MMMMM dd, yyyy");
String dateString = format2.format(date);
System.out.println(dateString); //<- prints January 01, 2019
How to use the SimpleDateFormat?
Java provides a class called a SimpleDateFormat that allows you to format and parse dates in the as per your requirements.
You can use the above characters to specify the format - For example:
1) Date format required: 2019.01.01 20:20:45 PST
The appropriate date format specified will be- yyyy.MM.dd HH:mm:ss zzz
2) Date format required:09:30:00 AM 01-Jan-2019
The appropriate date format specified will be-hh:mm:ss a dd-MMM-yyyy
Tip: Be careful with the letter capitalization. If you mistake M with m, you will undesired results!
Let's learn this with a code example.
import java.text.SimpleDateFormat;
import java.util.Date;
public class TestDates_Format {
public static void main(String args[]) {
Date objDate = new Date(); // Current System Date and time is assigned to objDate
System.out.println(objDate);
String strDateFormat = "hh:mm:ss a dd-MMM-yyyy"; //Date format is Specified
SimpleDateFormat objSDF = new SimpleDateFormat(strDateFormat); //Date format string is passed as an argument to the Date format object
System.out.println(objSDF.format(objDate)); //Date formatting is applied to the current date
}
}
Output :
Sat Mar 02 16:37:59 UTC 2019
04:37:59 PM 02-Mar-2019

I have a date in the format 11-NOV-13
When i convert the date i get the value Sat Nov 11 00:00:00 IST 13.
But i want the converted date to be in the format Sat Nov 11 00:00:00 IST 2013.
Though i have used the dateformat it is not taking it. Can anyone point me where i am wrong?
Below is the code i have been working on
DateFormat format = new SimpleDateFormat("dd-MMM-yyyy", Locale.ENGLISH);
Date myDate = format.parse("11-NOV-13");
Change the format to:
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
You need to make the year 2 numbers:
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
You can reference the docs here.
As you are not providing the full year you need
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
Date myDate = format.parse("11-NOV-13");
System.out.println(myDate);
Change to this format:
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
Date myDate = format.parse("11-NOV-13");
String formattedDate = sdf.format(myDate);
I have a date, "2015-06-08". I want convert it to "08 June 2015"
String oldDateString = "2015-06-08";
SimpleDateFormat oldDateFormat = new SimpleDateFormat("yyyy-mm-dd", Locale.getDefault());
SimpleDateFormat newDateFormat = new SimpleDateFormat("dd MMMM yyyy", Locale.getDefault());
Date date = oldDateFormat.parse(oldDateString);
String result = newDateFormat.format(date);
but this does not work correctly. It returns "08 January 2015". What have I done wrong?
Use yyyy-MM-dd insted yyyy-mm-dd because 'm' in lowercase is minutes.

I have to compare 2 dates which are in String format as: Fri Aug 23 17:03:19 IST 2013
I am trying to use new SimpleDateFormat("dd-MM-yyyy HH-mm-ss") to convert in DateTime so that dates can be comparable .
tempTimeStamp=Fri Aug 23 17:03:19 IST 2013
DateFormat df = new SimpleDateFormat("dd-MM-yyyy HH-mm-ss");
Date startDate;
startDate = df.parse(tempTimestamp);
String newDateString = df.format(startDate);
But its showing error object of this type can't be converted in DateFormat.Please help..
You were using the wrong format to try and parse the datetime string, try using the following snippet:
String tempTimeStamp="Fri Aug 23 17:03:19 IST 2013"
DateFormat df = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy");
Date startDate = startDate = df.parse(tempTimestamp);
String newDateString = df.format(startDate);
You can look up more on the patterns for defining the date time format at http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html
Your expected format doesn't matches with the one provided.
The format of your SimpleDateFormat does not match that of the String that you are using.
The input String should match dd-MM-yyyy HH-mm-ss
If you are wanting simply to format the output of a Date, then no parsing of a String is necessary.
I need to convert from Date(the object :insuree.getBirthDate()) into Calendar(the object : request_MDP.setBIRTH_DATE)
but i get the error :
21/02/13 15:20:26 ERROR [MdmInsureeService]: ServiceProxy Update
exception: 'Unparseable date: "Mon Nov 15 15:00:00 IST 1982"' 21/02/13
15:20:26 ERROR [MdmInsureeService]: ServiceProxy Update exception
(toString): 'java.text.ParseException: Unparseable date: "Mon Nov 15
15:00:00 IST 1982"
This is my code :
DateFormat formatter = new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Date date_MDP =(Date)formatter.parse(insuree.getBirthDate().toString());
Calendar cal_MDP=Calendar.getInstance();
cal_MDP.setTime(date_MDP);
request_MDP.setBIRTH_DATE(cal_MDP);
How can I convert the Date(insuree.getBirthDate()) into Calendar(setBIRTH_DATE) ?
Thanks
try this code:
SimpleDateFormat df = new SimpleDateFormat("KK:mm aa");
Date date = df.parse("10:30 PM");
System.out.print(date);
Calendar cal = GregorianCalendar.getInstance();
cal.setTimeInMillis(date.getTime());
System.out.print(cal.getTime());
Is it possible that you run this code on a system with a non-English locale? Such a locale might not recognize the weekday or month in your example date ("Mon Nov 15 15:00:00 IST 1982"), because it uses different names (e.g. "Tue" would be "Di" in German).
Replace the first line in your snippet with
DateFormat formatter =
new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy", Locale.US);
and it will work with your example date. Either way, you have to use the same format and locale that was used to generate those date strings. Maybe you can even convince the generator to use some standard format like ISO 8601.
