I'm kind of stuck on date and time.
I want my program to create the date like this "20121217". The first 4 letters are the year, the second 2 letters are the month and the last 2 are the day. year+month+day
The time is "112233" hour+minute+second
Thanks for your help!
That's a formatting issue. Java uses java.util.Date and java.text.DateFormat and java.text.SimpleDateFormat for those things.
DateFormat dateFormatter = new SimpleDateFormat("yyyyMMdd hhmmss");
dateFormatter.setLenient(false);
Date today = new Date();
String s = dateFormatter.format(today);
You can do something like this:
Calendar c = Calendar.getInstance();
String date = c.get(Calendar.YEAR) + c.get(Calendar.MONTH) + c.get(Calendar.DATE);
String time = c.get(Calendar.HOUR) + c.get(Calendar.MINUTE) + c.get(Calendar.SECOND);
Change any specific format of time or date as you need.
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
currentDateandTime = sdf.format(new Date());
For date:
DateFormat df = new SimpleDateFormat("yyyyMMdd");
String strDate = df.format(new Date());
For time:
DateFormat df = new SimpleDateFormat("hhmmss");
String strTime = df.format(new Date());
This works,
String currentDateTime;
SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
currentDateTime = sdf1.format(new Date());
What you're looking for is the SimpleDateFormat in Java... Take a look at this page.
Try this for your need:
SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd hhmmss");
Date parsed = format.parse(new Date());
System.out.println(parsed.toString());
You can use following method to get current time
/**************************************************************
* getCurrentTime() it will return system time
*
* #return
****************************************************************/
public static String getCurrentTime() {
DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd HHmmss");
Calendar cal = Calendar.getInstance();
return dateFormat.format(cal.getTime());
}// end of getCurrentTime()

// For Date validation
SimpleDateFormat simpleDateFormat1 = new SimpleDateFormat("dd/MM/yyyy");
String datechosen = dateText.getText().toString() ;
Date dateselected = simpleDateFormat1.parse(datechosen);
System.out.println(dateselected);
// For Time validation
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:mm");
String timechosen = timeText.getText().toString();
Date timeselected = simpleDateFormat.parse(timechosen);
Calendar cal = Calendar.getInstance();
cal.setTime(timeselected);
cal.add(Calendar.HOUR, noofhourselected);
cal.add(Calendar.MINUTE, noofminselected);
timeselected = cal.getTime();
System.out.println(timeselected);
I am working on converting the string which i have into the date and time format. For example, the string datechosen contain "26/10/2020". I am able to to convert it into date format and print it out.
But for the time string, i am unable to print them out. I am facing the error below:
Screenshot of the log message
But if i swap the position of the codes the other way round,
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:mm");
String timechosen = timeText.getText().toString();
Date timeselected = simpleDateFormat.parse(timechosen);
Calendar cal = Calendar.getInstance();
cal.setTime(timeselected);
cal.add(Calendar.HOUR, noofhourselected);
cal.add(Calendar.MINUTE, noofminselected);
timeselected = cal.getTime();
System.out.println(timeselected);
// For Date validation
SimpleDateFormat simpleDateFormat1 = new SimpleDateFormat("dd/MM/yyyy");
String datechosen = dateText.getText().toString() ;
Date dateselected = simpleDateFormat1.parse(datechosen);
System.out.println(dateselected);
The time will be printed instead
These are the two input fields
You are setting date in wrong format for time. for cal.setTime(timeselected); setTime takes Date Refer java doc
Use same format as used for Date.
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

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];
I hope you will like my approach, if you have liked it, don't forget to give it an upvote, so that others will consider it.
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 implementing custom listview in android with image, text and date but when i call getDate method it will work but return 1/1/1970 instead of showing my system date?
You can just use new java.util.Date() and it will contain the actual date. You can also use Calendar.getInstance() or long time = System.currentTimeMillis(); new Date(time);
FYI,
getDate() => This method is deprecated. And it returns the day of the month.
You can use:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); // you can mention any format which you want
String currentDateandTime = sdf.format(new Date());
Use this:
Calendar c = Calendar.getInstance();
int seconds = c.get(Calendar.SECOND)
android calender documentation
here is the complete solution.where you can get the date and also access it in the form of string.
private final static String getDateTime() {
DateFormat df = new SimpleDateFormat("yyyy-MM-dd_hh:mm:ss");
Log.i("Log", "date is: "+df.format(new Date()));
return df.format(new Date());
}
you can try this
DateFormat date = new SimpleDateFormat("yyyy-MM-dd_hh:mm:ss");
Log.i("Log", "date is: "+date.format(new Date()));
date.format(new Date());
use this:
long dtMili = System.currentTimeMillis();
String date = new java.text.SimpleDateFormat("dd-MM-yy").format(new java.util.Date(dtMili));
Calendar ci = Calendar.getInstance();
CiDateTime = "" + (ci.get(Calendar.MONTH) + 1) +
"/" + ci.get(Calendar.DAY_OF_MONTH) +
"/" + ci.get(Calendar.YEAR);
String visitdatetime = CiDateTime + "" +
ci.get(Calendar.HOUR_OF_DAY) + ":" +
ci.get(Calendar.MINUTE) + ":" +
ci.get(Calendar.SECOND);
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy hh:mm a");
I am getting from the server in 24 hours format.but want to show my date like MM/dd/yyyy hh:mm AM/PM like 12 hrs format.
Did you try this ?
SimpleDateFormat dateFromat= new SimpleDateFormat("MM/dd/yyyy hh:mm aa");
Date today = new Date();
String todayStr = dateFromat.format(today);
Below function may be useful to you. This will convert time from 24 hours to 12 hours
public static String Convert24to12(String time)
{
String convertedTime ="";
try {
SimpleDateFormat displayFormat = new SimpleDateFormat("hh:mm a");
SimpleDateFormat parseFormat = new SimpleDateFormat("HH:mm:ss");
Date date = parseFormat.parse(time);
convertedTime=displayFormat.format(date);
System.out.println("convertedTime : "+convertedTime);
} catch (final ParseException e) {
e.printStackTrace();
}
return convertedTime;
//Output will be 10:23 PM
}
public static final String TIME_FORMAT = "hh:mm aa";
SimpleDateFormat TimeFormat = new SimpleDateFormat(TIME_FORMAT);
Calendar ATime = Calendar.getInstance();
String Timein12hourFormat = TimeFormat.format(ATime.getTime());
try with this answer this is shortest and best answer on stack.
Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss aa");
Datetime = sdf.format(c.getTime());
System.out.println("============="+Datetime);

Here is the answer to get a data in US-English Format date/time using a 12 hour clock.
DateTime.Now.ToString("MM/d/yyyy hh:mm:ss tt");
01/16/2014 03:53:57 PM
hh:mm a
Adding the 'a' should do the trick in displaying the am/pm
In angular i am using angular-bootsrap-datetimepicker and to display the selected date and time i am using this syntax
data-ng-model="event.start | date:'dd-MM-yyyy hh:mm a'"
use below format to 12 hour with am/pm
MM/dd/yyyy HH:mm:ss a
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());
