How to get difference between two dates in Days, Hours (24), Minutes (60), Seconds(60).

I have been go through
Android difference between Two Dates
How do I get difference between two dates in android?, tried every thing and post
but no help,
Here is my code..
try {
String FinalDate = "20-04-2018 08:00:00";
String CurrentDate = "26-04-2018 10:10:30";
Date date1;
Date date2;
SimpleDateFormat dates = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
date1 = dates.parse(CurrentDate);
date2 = dates.parse(FinalDate);
/*long difference = date1.getTime() - date2.getTime();
long differenceInMinutes = difference / (60 * 1000);
long differenceInSeconds = difference / 1000;
String strMinuteDifference = Long.toString(differenceInMinutes);
String strSecondsDifference = Long.toString(differenceInSeconds);*/
long difference = date1.getTime() - date2.getTime();
long seconds = difference / 1000;
long minutes = seconds / 60;
long hours = minutes / 60;
long days = hours / 24;
Log.e("TAG_5", "CurrentDate is : " + date1);
Log.e("TAG_5", "Final date is : " + date2);
Log.e("TAG_5", "Day Difference: " + days);
Log.e("TAG_5", "hours Difference: " + hours);
Log.e("TAG_5", "Minute Difference: " + minutes);
Log.e("TAG_5", "Seconds Difference: " + seconds);
} catch (Exception exception) {
Log.e("TAG_5", "exception " + exception);
}
and the output is
E/TAG_5: CurrentDate is : Thu Apr 26 10:10:30 GMT+05:30 2018
E/TAG_5: Demo date is : Fri Apr 20 08:00:00 GMT+05:30 2018
E/TAG_5: Day Difference: 6
E/TAG_5: hours Difference: 146
E/TAG_5: Minute Difference: 8770
E/TAG_5: Seconds Difference: 526230
Its seems be like the code is Calculate All the Hours, Minutes, Seconds between those two dates but
I want Output be like...
Hours should be like 2 hours, 10 hours or 23 hours but not more than 24, because 25 hours will be new day so that should be 1 Day and 1 hour.
and Minutes be like 10 minutes 35 minutes or 59 minutes, but not more than 60
same goes for Seconds, it should be 12 seconds, 40 seconds or 59 seconds but not more than 60.
So how can i achieve this ?
To calculate the "rest" hours like you said. (So below 24 hours) you can use modulo.
In computing, the modulo operation finds the remainder after division
of one number by another (sometimes called modulus).
int hours = theAmountOfHours % 24
In your example
Log.e("TAG_5", "Day Difference: " + days);
Log.e("TAG_5", "hours Difference: " + hours % 24);
Log.e("TAG_5", "Minute Difference: " + minutes % 60);
Log.e("TAG_5", "Seconds Difference: " + seconds % 60);

Try this method
public void printDifferenceDateForHours(Date startDate, Date endDate) {
//milliseconds
long different = endDate.getTime() - startDate.getTime();
long secondsInMilli = 1000;
long minutesInMilli = secondsInMilli * 60;
long hoursInMilli = minutesInMilli * 60;
long daysInMilli = hoursInMilli * 24;
//TODO Here you will get the days
long elapsedDays = different / daysInMilli;
different = different % daysInMilli;
//TODO Here you will get the hours
long elapsedHours = different / hoursInMilli;
different = different % hoursInMilli;
//TODO Here you will get the minute
long elapsedMinutes = different / minutesInMilli;
different = different % minutesInMilli;
//TODO Here you will get the second
long elapsedSeconds = different / secondsInMilli;
}
try {
String FinalDate = "20-04-2018 08:00:00";
String CurrentDate = "26-04-2018 10:10:30";
Date date1;
Date date2;
SimpleDateFormat dates = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
date1 = dates.parse(CurrentDate);
date2 = dates.parse(FinalDate);
long seconds = 1000;
long minutes = 60 * seconds;
long hours = 60 * minutes;
long days = 24 * hours;
long weeks = 7 * days;
long months = 30 * days;
long year = 365 * days;
long difference = date1.getTime() - date2.getTime();
long differenceInDays = difference / days;
difference = difference - (differenceInDays * days);
long differenceInHours = (difference) / hours;
difference = difference - (differenceInHours * hours);
long differenceInMin = (difference) / minutes;
difference = difference - (differenceInMin * minutes);
long differenceInSecond = difference / seconds;
Log.e("TAG_5", "CurrentDate is : " + date1);
Log.e("TAG_5", "Final date is : " + date2);
Log.e("TAG_5", "Day Difference: " + differenceInDays);
Log.e("TAG_5", "hours Difference: " + differenceInHours);
Log.e("TAG_5", "Minute Difference: " + differenceInMin);
Log.e("TAG_5", "Seconds Difference: " + differenceInSecond);
} catch (Exception exception) {
Log.e("TAG_5", "exception " + exception);
}
Here i have calculated only day,month,min,second you can calculate year,month,week same way
You can use epoch time (unix timestamp) of both the dates and calculate the days, hours, mins and sms difference yourself using the modulo (% - remainder) operator.
You can do this way, I hope it help for you. thanks
String CurrentDate = "26-04-2018 10:10:30";
String FinalDate = "20-04-2018 08:00:00";
long diffInMillisec = CurrentDate.getTime() - FinalDate.getTime();
long diffInSec = TimeUnit.MILLISECONDS.toSeconds(diffInMillisec);
seconds = diffInSec % 60;
diffInSec/= 60;
minutes =diffInSec % 60;
diffInSec /= 60;
hours = diffInSec % 24;
diffInSec /= 24;
days = diffInSec;`
1.Divide the difference by days to get number of days/hours/minutes/etc.
2.perform Modulo to get the remaining seconds.
Use
long difference="your difference result here";
long seconds =1000;
long minutes =60*seconds;
long hours = 60*minutes;
long days = 24*hours;
long weeks=7*days;
long months=30*days;
long year=365*days;
if(difference>year) {
Log.d("year", String.valueOf(difference / year));
difference = difference % year;
}
if(difference>months) {
Log.d("months", String.valueOf(difference / months));
difference = difference % months;
}
if(difference>weeks) {
Log.d("weeks", String.valueOf(difference / weeks));
difference = difference % weeks;
}
if(difference>days) {
Log.d("days", String.valueOf(difference / days));
difference = difference % days;
}
if(difference>hours) {
Log.d("hours", String.valueOf(difference / hours));
difference = difference % hours;
}
if(difference>minutes) {
Log.d("minutes", String.valueOf(difference / minutes));
difference = difference % minutes;
}
if(difference>0)
Log.d("seconds", String.valueOf(difference/seconds ));
I have android application and I need to display the different between two date but I have a problem in this case
For example :
When tried to display the different between date 28/12/2016 and 01/01/2017
the result is 339 days , How I can solve this and when tried to display, I got a correct result. This is my code:
public void Cal() {
java.text.SimpleDateFormat simpleDateFormat =new java.text.SimpleDateFormat("yyyy/mm/dd hh:mm:ss");
try {
Date date2 = simpleDateFormat.parse("2017/01/01"+ " " + "11:30:00");//end_date
Date date1 = simpleDateFormat.parse("2016/12/28"+ " " + "11:30:00");//start_date
printDifference(date1, date2);
} catch (ParseException e) {
e.printStackTrace();
}
}
public void printDifference(Date startDate, Date endDate) {
long different = endDate.getTime() - startDate.getTime();
System.out.println("startDate : " + startDate);
System.out.println("endDate : "+ endDate);
System.out.println("different : " + different);
long secondsInMilli = 1000;
long minutesInMilli = secondsInMilli * 60;
long hoursInMilli = minutesInMilli * 60;
long daysInMilli = hoursInMilli * 24;
long elapsedDays = different / daysInMilli;
different = different % daysInMilli;
long elapsedHours = different / hoursInMilli;
different = different % hoursInMilli;
long elapsedMinutes = different / minutesInMilli;
different = different % minutesInMilli;
long elapsedSeconds = different / secondsInMilli;
System.out.printf(
"%d days, %d hours, %d minutes, %d seconds%n",
elapsedDays,
elapsedHours, elapsedMinutes, elapsedSeconds);
}
The pattern you used when constructing your SimpleDateFormat has a problem. You used this:
yyyy/mm/dd hh:mm:ss
But you should have used this:
yyyy/MM/dd hh:mm:ss
From the documentation, lowercase m means minutes in an hour, which is appropriate for the timestamp portion of your format string, while uppercase M means months in the year.
I am making a reminder app and for that I need to calculate the date difference between the stored date in database with the current date. I have tried the julianday method but it doesn't seems to work. Please give the relevant sqlite query. I am new to android so please help!!!
At First Query Data from database for getting date then convert this date data to Date Format
Covert Date to Date Format
String dateString = "03/26/2012 11:49:00 AM";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss aa");
Date convertedDate = new Date();
try {
convertedDate = dateFormat.parse(dateString);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Then get System Current date and Compare database data to System current date.
Date Different Method
public void printDifference(Date startDate, Date endDate){
//milliseconds
long different = endDate.getTime() - startDate.getTime();
System.out.println("startDate : " + startDate);
System.out.println("endDate : "+ endDate);
System.out.println("different : " + different);
long secondsInMilli = 1000;
long minutesInMilli = secondsInMilli * 60;
long hoursInMilli = minutesInMilli * 60;
long daysInMilli = hoursInMilli * 24;
long elapsedDays = different / daysInMilli;
different = different % daysInMilli;
long elapsedHours = different / hoursInMilli;
different = different % hoursInMilli;
long elapsedMinutes = different / minutesInMilli;
different = different % minutesInMilli;
long elapsedSeconds = different / secondsInMilli;
System.out.printf(
"%d days, %d hours, %d minutes, %d seconds%n",
elapsedDays,
elapsedHours, elapsedMinutes, elapsedSeconds);
}
I need to get Day Hours Minutes to reach certain date
example :
Date = "14-08-2015 16:38:28"
Current_Date = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss").format(new Date());
and to reach that Date the result will be
2 Days and 1 hour and 30 minutes
Simple searching on google I got
String dateStart = "01/14/2012 09:29:58";
String dateStop = "01/15/2012 10:31:48";
//HH converts hour in 24 hours format (0-23), day calculation
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Date d1 = null;
Date d2 = null;
try {
d1 = format.parse(dateStart);
d2 = format.parse(dateStop);
//in milliseconds
long diff = d2.getTime() - d1.getTime();
long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);
System.out.print(diffDays + " days, ");
System.out.print(diffHours + " hours, ");
System.out.print(diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");
} catch (Exception e) {
e.printStackTrace();
}

How to find the duration of difference between two dates in java?
Calculate date/time difference in java
You could use:
Calendar c = Calendar.getInstance();
int seconds = c.get(Calendar.SECOND);
There are plenty of constants in Calendar for everything you need. Edit: Calendar class documentation
I have two date like:
String date_1="yyyyMMddHHmmss";
String date_2="yyyyMMddHHmmss";
I want to print the difference like:
2d 3h 45m
How can I do that? Thanks!

different : 291945000
3 days, 9 hours, 5 minutes, 45 seconds
Date userDob = new SimpleDateFormat("yyyy-MM-dd").parse(dob);
Date today = new Date();
long diff = today.getTime() - userDob.getTime();
int numOfDays = (int) (diff / (1000 * 60 * 60 * 24));
int hours = (int) (diff / (1000 * 60 * 60));
int minutes = (int) (diff / (1000 * 60));
int seconds = (int) (diff / (1000));
Short & Sweet:
/**
* Get a diff between two dates
*
* #param oldDate the old date
* #param newDate the new date
* #return the diff value, in the days
*/
public static long getDateDiff(SimpleDateFormat format, String oldDate, String newDate) {
try {
return TimeUnit.DAYS.convert(format.parse(newDate).getTime() - format.parse(oldDate).getTime(), TimeUnit.MILLISECONDS);
} catch (Exception e) {
e.printStackTrace();
return 0;
}
}
Usage:
int dateDifference = (int) getDateDiff(new SimpleDateFormat("dd/MM/yyyy"), "29/05/2017", "31/05/2017");
System.out.println("dateDifference: " + dateDifference);
Output:
dateDifference: 2
Kotlin Version:
#ExperimentalTime
fun getDateDiff(format: SimpleDateFormat, oldDate: String, newDate: String): Long {

DurationUnit.MILLISECONDS
)
} catch (e: Exception) {

}
This works and convert to String as a Bonus ;)
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Date date1;
Date date2;
SimpleDateFormat dates = new SimpleDateFormat("MM/dd/yyyy");
//Setting dates
date1 = dates.parse(CurrentDate);
date2 = dates.parse(FinalDate);
//Comparing dates
long difference = Math.abs(date1.getTime() - date2.getTime());
long differenceDates = difference / (24 * 60 * 60 * 1000);
//Convert long to String
String dayDifference = Long.toString(differenceDates);
Log.e("HERE","HERE: " + dayDifference);
} catch (Exception exception) {
Log.e("DIDN'T WORK", "exception " + exception);
}
}
It will give you difference in months
long milliSeconds1 = calendar1.getTimeInMillis();
long milliSeconds2 = calendar2.getTimeInMillis();
long periodSeconds = (milliSeconds2 - milliSeconds1) / 1000;
long elapsedDays = periodSeconds / 60 / 60 / 24;
System.out.println(String.format("%d months", elapsedDays/30));
Here is the modern answer. It’s good for anyone who either uses Java 8 or later (which doesn’t go for most Android phones yet) or is happy with an external library.
String date1 = "20170717141000";
String date2 = "20170719175500";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");
Duration diff = Duration.between(LocalDateTime.parse(date1, formatter),
LocalDateTime.parse(date2, formatter));
if (diff.isZero()) {
System.out.println("0m");
} else {
long days = diff.toDays();
if (days != 0) {
System.out.print("" + days + "d ");
diff = diff.minusDays(days);
}
long hours = diff.toHours();
if (hours != 0) {
System.out.print("" + hours + "h ");
diff = diff.minusHours(hours);
}
long minutes = diff.toMinutes();
if (minutes != 0) {
System.out.print("" + minutes + "m ");
diff = diff.minusMinutes(minutes);
}
long seconds = diff.getSeconds();
if (seconds != 0) {
System.out.print("" + seconds + "s ");
}
System.out.println();
}
This prints
2d 3h 45m
In my own opinion the advantage is not so much that it is shorter (it’s not much), but leaving the calculations to an standard library is less errorprone and gives you clearer code. These are great advantages. The reader is not burdened with recognizing constants like 24, 60 and 1000 and verifying that they are used correctly.
I am using the modern Java date & time API (described in JSR-310 and also known under this name). To use this on Android under API level 26, get the ThreeTenABP, see this question: How to use ThreeTenABP in Android Project. To use it with other Java 6 or 7, get ThreeTen Backport. With Java 8 and later it is built-in.
With Java 9 it will be still a bit easier since the Duration class is extended with methods to give you the days part, hours part, minutes part and seconds part separately so you don’t need the subtractions. See an example in my answer here.
I use this:
send start and end date in millisecond
public int GetDifference(long start,long end){
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(start);
int hour = cal.get(Calendar.HOUR_OF_DAY);
int min = cal.get(Calendar.MINUTE);
long t=(23-hour)*3600000+(59-min)*60000;
t=start+t;
int diff=0;
if(end>t){
diff=(int)((end-t)/ TimeUnit.DAYS.toMillis(1))+1;
}
return diff;
}
You can calculate the difference in time in miliseconds using this method and get the outputs in seconds, minutes, hours, days, months and years.
You can download class from here: DateTimeDifference GitHub Link
Simple to use
long currentTime = System.currentTimeMillis();
long previousTime = (System.currentTimeMillis() - 864000000); //10 days ago
Log.d("DateTime: ", "Difference With Second: " + AppUtility.DateTimeDifference(currentTime, previousTime, AppUtility.TimeDifference.SECOND));
Log.d("DateTime: ", "Difference With Minute: " + AppUtility.DateTimeDifference(currentTime, previousTime, AppUtility.TimeDifference.MINUTE));
You can compare the example below
if(AppUtility.DateTimeDifference(currentTime, previousTime, AppUtility.TimeDifference.MINUTE) > 100){
Log.d("DateTime: ", "There are more than 100 minutes difference between two dates.");
}else{
Log.d("DateTime: ", "There are no more than 100 minutes difference between two dates.");
}
Try this out.
int day = 0;
int hh = 0;
int mm = 0;
try {
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy 'at' hh:mm aa");
Date oldDate = dateFormat.parse(oldTime);
Date cDate = new Date();
Long timeDiff = cDate.getTime() - oldDate.getTime();
day = (int) TimeUnit.MILLISECONDS.toDays(timeDiff);
hh = (int) (TimeUnit.MILLISECONDS.toHours(timeDiff) - TimeUnit.DAYS.toHours(day));
mm = (int) (TimeUnit.MILLISECONDS.toMinutes(timeDiff) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(timeDiff)));
} catch (ParseException e) {
e.printStackTrace();
}
if (mm <= 60 && hh!= 0) {
if (hh <= 60 && day != 0) {
return day + " DAYS AGO";
} else {
return hh + " HOUR AGO";
}
} else {
return mm + " MIN AGO";
}
DateTime start = new DateTime(2013, 10, 20, 5, 0, 0, Locale);
DateTime end = new DateTime(2013, 10, 21, 13, 0, 0, Locale);
Days.daysBetween(start.toLocalDate(), end.toLocalDate()).getDays()
it returns how many days between given two dates, where DateTime is from joda library
I arranged a little. This works great.

Here's the simple solution:
fun printDaysBetweenTwoDates(): Int {
val dateFormat = SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH)
val endDateInMilliSeconds = dateFormat.parse("26-02-2022")?.time ?: 0
val startDateInMilliSeconds = dateFormat.parse("18-02-2022")?.time ?: 0
return getNumberOfDaysBetweenDates(startDateInMilliSeconds, endDateInMilliSeconds)
}
private fun getNumberOfDaysBetweenDates(
startDateInMilliSeconds: Long,
endDateInMilliSeconds: Long
): Int {
val difference = (endDateInMilliSeconds - startDateInMilliSeconds) / (1000 * 60 * 60 * 24).toDouble()
val noOfDays = Math.ceil(difference)
return (noOfDays).toInt()
}
When you use Date() to calculate the difference in hours is necessary configure the SimpleDateFormat() in UTC otherwise you get one hour error due to Daylight SavingTime.
You can generalize this into a function that lets you choose the output format
private String substractDates(Date date1, Date date2, SimpleDateFormat format) {
long restDatesinMillis = date1.getTime()-date2.getTime();
Date restdate = new Date(restDatesinMillis);
return format.format(restdate);
}
Now is a simple function call like this, difference in hours, minutes and seconds:
SimpleDateFormat formater = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
Date date1 = formater.parse(dateEnd);
Date date2 = formater.parse(dateInit);
String result = substractDates(date1, date2, new SimpleDateFormat("HH:mm:ss"));
txtTime.setText(result);
} catch (ParseException e) {
e.printStackTrace();
}
