Please take a look at the following code:
Date date = new GregorianCalendar (2019, Calendar.DECEMBER, 30).getTime ();
System.out.println (date);
SimpleDateFormat formatter = new SimpleDateFormat ("dd.MM.YYYY");
System.out.println (formatter.format (date));
The output is as follow:
Mon Dec 30 00:00:00 CET 2019
30.12.2020
Look at the year. What is wrong?
Same problem with '2019-12-31' while '2019-12-29' is ok.
Best regards
Thomas

I have the following:
Date dateCommence = new SimpleDateFormat("YYYY-MM-DD HH:mm:ss").parse("2021-01-06 00:00:00");
But the dateCommence is the following:
Sun Dec 27 00:00:00 SAST 2020
Question
How do I convert the "2021-01-06 00:00:00" string to a date?
You were using the wrong date format mask. From the documentation, Y corresponds to the week year, and D is the day in year.
Try this version:
Date dateCommence = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
.parse("2021-01-06 00:00:00");
System.out.println(dateCommence);
This prints:
Wed Jan 06 00:00:00 CET 2021

I have timestamp of the format 2020-05-12 12:00:00+00 . How can I parse into Java.util.Date and Java.time.Instant.
Seemingly basic question, but I suspect it is the source of the problem that I am yet to solve in thread
Java 8 introduced DateTimeFormatter. Here is the link to the DateTimeFormatter Documentation.
For example:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("uuuu-MM-dd HH:mm:ssx");
String tsFromDb = "2020-05-12 12:00:00+00";
Instant inst = formatter.parse(tsFromDb, Instant::from);
System.out.println(inst);
Output:
2020-05-12T12:00:00Z
If you need a java.util.Date:
Date oldfashionedDate = Date.from(inst);
System.out.println(oldfashionedDate);
Output in America/Tijuana time zone:
Tue May 12 05:00:00 PDT 2020

Difference between 'YYYY' and 'yyyy' in NSDateFormatter

Due to the new year,I detected a bug in my project.
I am showing date and time in my order history using the following code:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("h:mm a MM/dd/YY", Locale.US).withZone(ZoneId.systemDefault());
String formattedOrderDate = formatter.withZone(ZoneId.of(order.timeZone)).format(order.order.pickupAt);
textView.setText(formattedOrderDate );
Here are the values received from server:
order.order.pickupAt = {ZonedDateTime#8390} "2020-01-02T17:50Z"
order.timeZone = "America/Denver"
But the output is not showing the perfect year for the end of December:
As you can clearly see, year 2019 is showing as 2020.
But it is only showing for the last of December.Another order from mid of December is showing the correct date(year).
I am not able to detect what is going wrong over here.I am suspecting that this might be due to the timezone(America/Denver).But I have changed the timezone to my local timezone,still it is showing 2020 instead of 2019.
Use yy instead of YY
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("h:mm a MM/dd/yy", Locale.US).withZone(ZoneId.systemDefault());
String formattedOrderDate = formatter.withZone(ZoneId.of(order.timeZone)).format(order.order.pickupAt);
textView.setText(formattedOrderDate );
YY is for week-based calendar year and yy is for calendar year. Last few days of December was actually the first week of 2020, so it is showing 2020 for those days.
Change your code to use yy, then it will show correct year -
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("h:mm a MM/dd/yy", Locale.US).withZone(ZoneId.systemDefault());

Format of the data written to the file

How can i do that?
Thanks!!
Check out the the class SimpleDateFormat: https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html
This should work for your example:
String inputString = "Wed Mar 29 18:54:53 IST 2017";
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy", Locale.ENGLISH);
sdf.parse(inputString)

I receive DATETIME from mysql database in a format like this 2016-10-12 18:52:00. Is there an easy way to print it in a readable like 12 October 2016 6:52 pm in java or android?
You can do things like:
SimpleDateFormat simpleDate = new SimpleDateFormat("MM/DD/YYYY HH:mm:ss");
Date date = new Date();
String S = simpleDate.format(date); //This will give you like 11/20/2016 08:45:02
Now use this form and get the month name programatically according to your need.
