'how to convert milliseconds to date format in android?
I have milliseconds. I need it to be converted to date format of
example:
23/10/2011
How to achieve it?
Solution 1:[1]
Convert the millisecond value to Date instance and pass it to the choosen formatter.
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = formatter.format(new Date(dateInMillis)));
Solution 2:[2]
public static String convertDate(String dateInMilliseconds,String dateFormat) {
return DateFormat.format(dateFormat, Long.parseLong(dateInMilliseconds)).toString();
}
Call this function
convertDate("82233213123","dd/MM/yyyy hh:mm:ss");
Solution 3:[3]
DateFormat.getDateInstance().format(dateInMS);
Solution 4:[4]
tl;dr
Instant.ofEpochMilli( myMillisSinceEpoch ) // Convert count-of-milliseconds-since-epoch into a date-time in UTC (`Instant`).
.atZone( ZoneId.of( "Africa/Tunis" ) ) // Adjust into the wall-clock time used by the people of a particular region (a time zone). Produces a `ZonedDateTime` object.
.toLocalDate() // Extract the date-only value (a `LocalDate` object) from the `ZonedDateTime` object, without time-of-day and without time zone.
.format( // Generate a string to textually represent the date value.
DateTimeFormatter.ofPattern( "dd/MM/uuuu" ) // Specify a formatting pattern. Tip: Consider using `DateTimeFormatter.ofLocalized…` instead to soft-code the formatting pattern.
) // Returns a `String` object.
java.time
The modern approach uses the java.time classes that supplant the troublesome old legacy date-time classes used by all the other Answers.
Assuming you have a long number of milliseconds since the epoch reference of first moment of 1970 in UTC, 1970-01-01T00:00:00Z…
Instant instant = Instant.ofEpochMilli( myMillisSinceEpoch ) ;
To get a date requires a time zone. For any given moment, the date varies around the globe by zone.
ZoneId z = ZoneId.of( "Pacific/Auckland" ) ;
ZonedDateTime zdt = instant.atZone( z ) ; // Same moment, different wall-clock time.
Extract a date-only value.
LocalDate ld = zdt.toLocalDate() ;
Generate a String representing that value using standard ISO 8601 format.
String output = ld.toString() ;
Generate a String in custom format.
DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu" ) ;
String output = ld.format( f ) ;
Tip: Consider letting java.time automatically localize for you rather than hard-code a formatting pattern. Use the DateTimeFormatter.ofLocalized… methods.
About java.time
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.
Where to obtain the java.time classes?
- Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
- Java 9 brought some minor features and fixes.
- Java SE 6 and Java SE 7
- Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
- Android
- Later versions of Android (26+) bundle implementations of the java.time classes.
- For earlier Android (<26), the process of API desugaring brings a subset of the java.time functionality not originally built into Android.
- If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

try this code might help, modify it suit your needs
SimpleDateFormat format = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
Date d = format.parse(fileDate);
Solution 6:[6]
i finally find normal code that works for me
Long longDate = Long.valueOf(date);
Calendar cal = Calendar.getInstance();
int offset = cal.getTimeZone().getOffset(cal.getTimeInMillis());
Date da = new Date();
da = new Date(longDate-(long)offset);
cal.setTime(da);
String time =cal.getTime().toLocaleString();
//this is full string
time = DateFormat.getTimeInstance(DateFormat.MEDIUM).format(da);
//this is only time
time = DateFormat.getDateInstance(DateFormat.MEDIUM).format(da);
//this is only date
Solution 7:[7]
Short and effective:
DateFormat.getDateTimeInstance().format(new Date(myMillisValue))

Coverting epoch format to SimpleDateFormat in Android (Java / Kotlin)
input: 1613316655000
output: 2021-02-14T15:30:55.726Z
In Java
long milliseconds = 1613316655000L;
Date date = new Date(milliseconds);
String mobileDateTime = Utils.getFormatTimeWithTZ(date);
//method that returns SimpleDateFormat in String
public static String getFormatTimeWithTZ(Date currentTime) {
SimpleDateFormat timeZoneDate = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault());
return timeZoneString = timeZoneDate.format(currentTime);
}
In Kotlin
var milliseconds = 1613316655000L
var date = Date(milliseconds)
var mobileDateTime = Utils.getFormatTimeWithTZ(date)
//method that returns SimpleDateFormat in String
fun getFormatTimeWithTZ(currentTime:Date):String {
val timeZoneDate = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault())
return timeZoneString = timeZoneDate.format(currentTime)
}
Solution 10:[10]
Latest solution in Kotlin:
private fun getDateFromMilliseconds(millis: Long): String {
val dateFormat = "MMMMM yyyy"
val formatter = SimpleDateFormat(dateFormat, Locale.getDefault())
val calendar = Calendar.getInstance()
calendar.timeInMillis = millis
return formatter.format(calendar.time)
}
We need to add Locale as an argument of SimpleDateFormat or use LocalDate. Locale.getDefault() is a great way to let JVM automatically get the current location timezone.

public static Date getDateFromString(String date) {
Date dt = null;
if (date != null) {
for (String sdf : supportedDateFormats) {

dt = new Date(new SimpleDateFormat(sdf).parse(date).getTime());
break;
} catch (ParseException pe) {

return cal;
}
public static long getMiliSecondsFromString(String s_date){
Date date = getDateFromString(s_date);
Calendar cal = getCalenderFromDate(date);
return cal.getTimeInMillis();

public static String toDateStr(long milliseconds, String format)
{
Date date = new Date(milliseconds);
SimpleDateFormat formatter = new SimpleDateFormat(format, Locale.US);
return formatter.format(date);
}

I've been looking for an efficient way to do this for quite some time and the best I've found is:
DateFormat.getDateInstance(DateFormat.SHORT).format(new Date(millis));
Advantages:
- It's localized
- Been in Android since API 1
- Very simple
Disadvantages:
- Limited format options. FYI: SHORT is only a 2 digit year.
- You burn a Date object every time. I've looked at source for the other options and this is a fairly minor compared to their overhead.
You can cache the java.text.DateFormat object, but it's not threadsafe. This is OK if you are using it on the UI thread.
Solution 14:[14]
This is the easiest way using Kotlin
private const val DATE_FORMAT = "dd/MM/yy hh:mm"
fun millisToDate(millis: Long) : String {
return SimpleDateFormat(DATE_FORMAT, Locale.US).format(Date(millis))
}
Solution 15:[15]
Use SimpleDateFormat for Android N and above. Use the calendar for earlier versions for example:
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
fileName = new SimpleDateFormat("yyyy-MM-dd-hh:mm:ss").format(new Date());
Log.i("fileName before",fileName);
}else{
Calendar cal = Calendar.getInstance();
cal.add(Calendar.MONTH,1);
String zamanl =""+cal.get(Calendar.YEAR)+"-"+cal.get(Calendar.MONTH)+"-"+cal.get(Calendar.DAY_OF_MONTH)+"-"+cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE)+":"+cal.get(Calendar.SECOND);
fileName= zamanl;
Log.i("fileName after",fileName);
}
Output:
fileName before: 2019-04-12-07:14:47 // use SimpleDateFormat
fileName after: 2019-4-12-7:13:12 // use Calender

fun convertLongToTimeWithLocale(){
val dateAsMilliSecond: Long = 1602709200000
val date = Date(dateAsMilliSecond)
val language = "en"
val formattedDateAsDigitMonth = SimpleDateFormat("dd/MM/yyyy", Locale(language))
val formattedDateAsShortMonth = SimpleDateFormat("dd MMM yyyy", Locale(language))
val formattedDateAsLongMonth = SimpleDateFormat("dd MMMM yyyy", Locale(language))
Log.d("month as digit", formattedDateAsDigitMonth.format(date))
Log.d("month as short", formattedDateAsShortMonth.format(date))
Log.d("month as long", formattedDateAsLongMonth.format(date))
}
output:
month as digit: 15/10/2020
month as short: 15 Oct 2020
month as long : 15 October 2020
You can change the value defined as 'language' due to your require. Here is the all language codes: Java language codes
