Is there a way to get only the year from the Date class and parse it into a string?
Here is the code that I use:
Date d1 = new Date();
d1.getYear(); `
And how to set the date to DatTime.Now;
like in C#?
Use SimpleDateFormat.
SimpleDateFormat sdf = new SimpleDateFormat("yyyy");
System.out.println(sdf.format(new Date()));
Output:
2014
public static String getCurrentDate(String format) {
SimpleDateFormat sdfFrom = new SimpleDateFormat(format);
Calendar currentTime = Calendar.getInstance();
return (sdfFrom.format(currentTime.getTime()));
}
public static Date getCurrentDate() {
Calendar currentTime = Calendar.getInstance();
return currentTime.getTime();
}
try to use java 8 date

I am trying to Convert date and time i am receiving in MM/dd/yyyy hh:mm a format to milliseconds so that i can push the date as end date in google calendar. I am trying below code but i am getting error.
Code:
String myDate = "10/20/2017 8:10 AM";
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm a");
Date date = sdf.parse(myDate);
long millis = date.getTime();
Error:
java.text.ParseException: Unparseable date: "10/20/2017 8:10 AM" (at offset 16)
Try this .
String myDate = "10/20/2017 8:10 AM";
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy h:mm a", Locale.ENGLISH);
Date date = sdf.parse(myDate);
long millis = date.getTime();
Add Locale.ENGLISH in your code .
Your code seems to be OK, i've just added try/catch block:
try {
String myDate = "10/20/2017 8:10 AM";
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm a");
Date date = sdf.parse(myDate);
long millis = date.getTime();
System.out.println(date);
System.out.println(millis);
}
catch(Exception ex) {
System.out.println(ex);
}
This code prints 1508479800000 as millis. If you want to check it backwards try this:
String x = "1508479800000";
DateFormat formatter = new SimpleDateFormat("MM/dd/yyyy hh:mm a");
long milliSeconds= Long.parseLong(x);
System.out.println(milliSeconds);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(milliSeconds);
System.out.println(formatter.format(calendar.getTime()));
this will give you 10/20/2017 08:10 AM.
You can use SimpleDateFormat to do it. You just have to know 2 things.
All dates are internally represented in UTC
.getTime() returns the number of milliseconds since 1970-01-01 00:00:00 UTC.
package se.wederbrand.milliseconds;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
public class Main {
public static void main(String[] args) throws Exception {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
String inputString = "00:01:30.500";
Date date = sdf.parse("1970-01-01 " + inputString);
System.out.println("in milliseconds: " + date.getTime());
}
}

I want convert timestamp to date and set time in this day to 12.00.
How can I do this?
If I use this:
Date date = new Date(event.getActionDate()*1000);
I can't set hour or minutes to this date, becouse methods for this operations are deprecated.
Explanation:
I have timestamp -
1461924872 // Fri, 29 Apr 2016 10:14:32 GMT
I want change hour in this timestamp (10:14 to 00.00).
long timeInMillis = 1461877200000l;
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(timeInMillis);
System.out.println("Date1:"+calendar.getTime().toString());
calendar.set(Calendar.HOUR_OF_DAY, 0); //For 12 AM use 0 and for 12 PM use 12.
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Date date = calendar.getTime();
System.out.println("Date2:"+date.toString());
Calendar cal = Calendar.getInstance();
TimeZone tz = cal.getTimeZone();//get your local time zone.
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm a");
sdf.setTimeZone(tz);//set time zone.
String localTime = sdf.format(new Date(time) * 1000));
Date date = new Date();
date = sdf.parse(localTime);
private String getDate(String timeStampStr){
try{
DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
Date netDate = (new Date(Long.parseLong(timeStampStr)));
return sdf.format(netDate);
}
catch(Exception ex){
return dateInStr;
}
}
let me know if it is working?
I want to get time and date separately from timestamp.Please help me in these. My example of timestamp is 1378798459.
Thanks
//Try the following
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = formatter.format(new Date(Long.parseLong(YOUR TIMESTAMP VALUE)));
txtDate.setText(dateString);
//You can put your needed format here:
SimpleDateFormat formatter = new SimpleDateFormat("YOUR REQUIRED FORMAT");
Try this is working with me
public String getDateCurrentTimeZone(long timestamp) {
try{
Calendar calendar = Calendar.getInstance();
TimeZone tz = TimeZone.getDefault();
calendar.setTimeInMillis(timestamp * 1000);
calendar.add(Calendar.MILLISECOND, tz.getOffset(calendar.getTimeInMillis()));
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date currenTimeZone = (Date) calendar.getTime();
return sdf.format(currenTimeZone);
}catch (Exception e) {
}
return "";
}
Improving upon the answer given by Pratik Dasa
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
Here you can get various formats using the following syntax. You can play around with it by deleting or adding terms given below in the syntax.
Date and Time Pattern Result
----------------------------- ---------------------------------
"yyyy.MM.dd G 'at' HH:mm:ss z" 2001.07.04 AD at 12:08:56 PDT
"EEE, MMM d, ''yy" Wed, Jul 4, '01
"h:mm a" 12:08 PM
"hh 'o''clock' a, zzzz" 12 o'clock PM, Pacific Daylight Time
"K:mm a, z" 0:08 PM, PDT
"yyyyy.MMMMM.dd GGG hh:mm aaa" 02001.July.04 AD 12:08 PM
"EEE, d MMM yyyy HH:mm:ss Z" Wed, 4 Jul 2001 12:08:56 -0700
"yyMMddHHmmssZ" 010704120856-0700
"yyyy-MM-dd'T'HH:mm:ss.SSSZ" 2001-07-04T12:08:56.235-0700
"yyyy-MM-dd'T'HH:mm:ss.SSSXXX" 2001-07-04T12:08:56.235-07:00

String time = DateUtils.formatDateTime(this, 1378798459, DateUtils.FORMAT_SHOW_TIME);
String date = DateUtils.formatDateTime(this, 1378798459, DateUtils.FORMAT_SHOW_DATE);
Try this,
final Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Date date = cal.getTime();
mHour = date.getHours();
mMinute = date.getMinutes();
Only that:
long timestampString = Long.parseLong("yourString");
String value = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").
format(new java.util.Date(timestampString * 1000));
long dv = Long.valueOf(timestamp_in_string)*1000;// its need to be in milisecond
Date df = new java.util.Date(dv);
String vv = new SimpleDateFormat("MM dd, yyyy hh:mma").format(df);
From here.
you can use this
Long tsLong = System.currentTimeMillis();
String ts = tsLong.toString();
long millisecond = Long.parseLong(ts);
datetimeString = DateFormat.format("MM-dd-yyyy hh:mm:ss a", new Date(millisecond)).toString();
timeString = datetimeString.substring(11);
dateString = datetimeString.substring(0,10);
String t2 = datetimeString.substring(20,21);
The datetimeString contains the Date Time AM/PM data
timeString will give you the substring which contains the time only and the dateString is substring for date
The String t2 will give you whether it is AM or PM in the clock
int day, month, year;
int second, minute, hour;
GregorianCalendar date = new GregorianCalendar();
day = date.get(Calendar.DAY_OF_MONTH);
month = date.get(Calendar.MONTH);
year = date.get(Calendar.YEAR);
second = date.get(Calendar.SECOND);
minute = date.get(Calendar.MINUTE);
hour = date.get(Calendar.HOUR);
String data =(hour+ ':'+ ""+minute+ ':'+"" +second+"" +""+"" +day+"" +"/" +(month+1)+"" +"/"+ +year);
Toast.makeText(getActivity(), "Time stamp:"+data,Toast.LENGTH_LONG).show();
DateFormat dateFormat = DateFormat.getDateTimeInstance();
when.setText(dateFormat.format(new Date(timestamp * 1000)));
The timestamp is multiplied by 1000 for converting the seconds into milliseconds.
All the answers are great and they mainly focus on converting the unix timestamp to milliseconds first, which is correct.
I struggled to apply that because I must use 1000L in the conversion (instead of 1000 only). Here's my working code with time zone conversion
// Set TimeZone
SimpleDateFormat dateFormat = new SimpleDateFormat("MM-dd-yy h:mm a", Locale.US);
dateFormat.setTimeZone(getDeviceTimeZone());
// Set time
Date date = new Date(timestamp * 1000L);
return dateFormat.format(date);
For Android API 26 and above, you can just do
return Instant.ofEpochSecond( timestamp )
.atZone(ZoneId.of( timezone ))
.toLocalDateTime()
.toString();
The very best way to get day and date from the timestamp is that:
java.util.Date dayAndDate = new java.util.Date( (long) yourTimeStamp * 1000);
// object coming as like: Tue Feb 09
String day = dayAndDate.toString().split(" ")[0];
String month = dayAndDate.toString().split(" ")[1];
String date = dayAndDate.toString().split(" ")[2];

If you want to use time like in a WhatsApp message, You can use this method,
public static String millisToDateChat(long time) {
long currentTime = System.currentTimeMillis();
long defe = currentTime - time;
long time_in;
if(time!=0){
time_in = time;
}else{
time_in = currentTime;
defe = 0;
}
int s = (int)defe/1000;
int m = (int)defe/(1000*60);
int h = (int)defe/(1000*60*60);
int d = (int)defe/(1000*60*60*24);
int w = (int)defe/(1000*60*60*24*7);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(time_in);
Date date = calendar.getTime();
#SuppressLint("SimpleDateFormat") String formattedDate=(new SimpleDateFormat("HH:mm")).format(date);
#SuppressLint("SimpleDateFormat") String formattedYear=(new SimpleDateFormat("MMM d, ''yy")).format(date);
#SuppressLint("SimpleDateFormat") String formattedm=(new SimpleDateFormat("MMM d")).format(date);
if(d>365) {
return formattedYear;
}else if(s>172000){
return formattedm;
}else if(s>86400) {
return "Yest.";
}else{
return formattedDate;
}
}
I am having a date string 2012-11-21 13:11:25 which I get from local database. I have to convert this according to UTC settings and display it on a particular screen. So if its GMT+05:30 it should be displayed as 2012-11-21 18:41:25 on the screen. How can I do this conversion. I have checked some of the questions but that didn't work out.
I am able to get a Date object that returns something like Wed Nov 21 13:11:25 GMT+05:30 2012 after this I need to get the time as 18:41:25 and date as 11-21-2012
Thanks in advance
Your df and inputFmt must use the same format.
But I think you should do it like this:
Date myDate = new Date();
Calendar calendar = Calendar.getInstance();
calendar.setTimeZone(TimeZone.getTimeZone("UTC"));
calendar.setTime(myDate);
Date time = calendar.getTime();
SimpleDateFormat outputFmt = new SimpleDateFormat("MMM dd, yyy h:mm a zz");
String dateAsString = outputFmt.format(time);
System.out.println(dateAsString);
Get UTC from current time :
public String getCurrentUTC(){
Date time = Calendar.getInstance().getTime();
SimpleDateFormat outputFmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
outputFmt.setTimeZone(TimeZone.getTimeZone("UTC"));
return outputFmt.format(time);
}
Best way to get formatted string of Date in required format is
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US);
dateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
String formatted = dateFormat.format(date);
//This is my input date
String dtStart = "2019-04-24 01:22 PM";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm a");
Date date = null;
try {
date = format.parse(dtStart);
getDateInUTC(date)
} catch (ParseException e) {
e.printStackTrace();
}
//This Method use for convert Date into some UTC format
public static String getDateInUTC(Date date) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
String dateAsString = sdf.format(date);
System.out.println("UTC" + dateAsString);
return dateAsString;
}
How do i set the date to 25 -12(december)- current year.
eg.
I am using this code
public static Calendar defaultCalendar() {
Calendar currentDate = Calendar.getInstance();
currentDate.add(Calendar.YEAR,0);
currentDate.add(Calendar.MONTH, 12);
currentDate.add(Calendar.DATE,25);
return currentDate;
}
Something like this should work:
public static Calendar defaultCalendar() {
Calendar currentDate = Calendar.getInstance();
currentDate.set(currentDate.get(Calendar.YEAR),Calendar.DECEMBER,25);
return currentDate;
}
You're trying to add 12 months, instead of setting the month to December (which is month 11, because the Java API is horrible). You want something like:
public static Calendar defaultCalendar() {
Calendar currentDate = Calendar.getInstance();
currentDate.set(Calendar.MONTH, 11); // Months are 0-based!
currentDate.set(Calendar.DAY_OF_MONTH, 25); // Clearer than DATE
return currentDate;
}
Use this it found very usefull to me though :
Take a look at SimpleDateFormat.
The basics for getting the current time in ISO8601 format:
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mmZ");
String now = df.format(new Date());
For other formats:
DateFormat df = new SimpleDateFormat("MMM d, yyyy");
String now = df.format(new Date());
or
DateFormat df = new SimpleDateFormat("MM/dd/yy");
String now = df.format(new Date());
